The board comes pre-loaded with the SparkFun USB to Serial COM Port firmware. When the board plugs into a USB port, Windows will ask for a driver, point to the driver .inf file found here. The board should now enumerate as a 'SparkFun COM Port' and act the same as the SparkFun FTDI Basic. In other words, you can use it as a USB to serial bridge or you can use it to load code with Arduino. In addition, the pinout on the end of the board is the same as the FTDI Basic, which means you can plug it directly into boards like the Arduino Pro.

In addition to the USB to serial firmware, the board also has Atmel's DFU bootloader installed. For information on how to use the bootloader, see the readme file here. You will need to first install Atmel's FLIP software. The bootloader allows you to load your code over USB. See the LUFA project for more example projects.

There is also a selectable 3.3V/5V jumper to set the logic level and VCC voltage.

Note: If using this board to load code with the Arduino IDE, be sure to select the 'Arduino Pro (5V, 16MHz) w/ATmega328' as the device. If using the DFU bootloader with Atmel's FLIP software, be sure to select the AT90USB82 as the device in FLIP.

PCB edge mount Reverse Polarized - SMA RF connector. Perfect for prototyping with our RF ICs. This is a standard edge connector. The thickness between pins is 0.063" so that it can slide sideways onto a PCB. See the mechanical drawing to create your footprint.

The FCC is moving towards Part 15 compliance. All this means is that all the SMA RF connectors are changing gender. Really annoying for those of us who need to mate an antenna to an RF device. The FCC gender change was instituted to prevent home users from damaging RF equipment (think home WiFi) when screwing on an antenna. If all antennas are female, there is no way to damage the center connector. However, you have to be very sure now what kind of SMA connector you need.

These strips of flexible PCB are each populated with a  red surface mount LED and a 330 Ohm current limiting resistor. Flexible LED strips are the perfect way to add light to your project while retaining the greatest amount of flexibility. They are great for crafts, e-textiles, or any application where flexibility is a concern.

By using fusible interfacing you can iron the boards directly onto most fabrics. Also, because the flexible PCB material is a thin plastic film, you can easily hand-sew or machine-sew through them with conductive thread. The large, easy-to-connect pads can also be trimmed to whatever size you need.

These are sold in packs of 5.

Note: The star shape denotes the positive side of the LED.

It's blue! It's skinny! It's the Arduino Pro! SparkFun's minimal design approach to Arduino. This is a 5V Arduino running the 16MHz bootloader (select 'Arduino Duemilanove w/ 328' within the Arduino software). The power switch was moved to the side of the board (good idea Limor!) to allow control when a shield is attached.

Please note: The right-angle power switch is fragile. We're working on making the switch stronger. For now, please be gentle.

Arduino Pro does not come with connectors populated so that you can solder in any connector or wire with any orientation you need. We recommend first time Arduino users start with the Duemilanove. It's a great board that will get you up and running quickly. The Arduino Pro series is meant for advanced users that understand the limitations of system voltage (5V), lack of connectors, and USB off board.

We wanted Arduino Pro to be low profile. The DC power jack footprint is available, but not populated. We recommend running the board with a LiPo battery for better portability. You will need to use a 5v step up or DC to DC converter to get 5V from a 3.7V LiPo battery, see the related items below.

We really wanted to minimize the cost of an Arduino. The Arduino Pro is like the Arduino Duemilanove (same pin out) but to keep the cost low, we used all SMD components, made it two layer, etc. This board connects directly to the FTDI Basic Breakout board and supports auto-reset. The Arduino Pro also works with the FTDI cable but the FTDI cable does not bring out the DTR pin so the auto-reset feature will not work.

Can't decide which Arduino is right for you? Arduino buying guide!

Features:

• ATmega328 running at 16MHz external resonator. Select 'Arduino Duemilanove w/ 328' to get the delay functions to work correctly.
• USB connection off board
• 5V regulator
• Max 150mA output
• Over current protected
• Reverse polarity protected
• DC input 5V up to 12V
• Resettable fuse prevents damage to board in case of short
• Power select switch acts as on/off switch

The AVR Stick is a simple data logging device that instantiates itself as an HID keyboard and reports the voltages, along with a 'timestamp,' from two pins on an ATtiny85.  The device uses open source firmware availabe from Objective Development (http://www.obdev.at/vusb/) called V-USB to implement the USB 1.1 standard.  The code that runs the application was based on the EasyLogger example application from Objective development.

The default firmware runs simply enough: plug it in to a USB port on your computer, after the computer recognizes the device as a keyboard it will automatically start reporting the voltages. To get a series of measurements, open up a text or spreadsheet editor and plug the AVR stick in. The AVR Stick will automatically start inputting the voltage values to whatever program is active on the computer. The ADC is configured to use a 2.56V reference voltage, so don't try measuring anything higher than that without modifying the code!

This thing is meant to be hacked! Visit the Objective Development website to learn how others have used the USB stack to implement miscellaneous HID projects like keyboards, mice, joysticks, etc., etc., etc...

This is a simple board that no one really needs but it sure comes in handy. If you've ever tried to hook up an FTDI to something only to realize you need to swap the TX and RX, maybe you could use this board. Sure, you can grab some jumper wires and make your own, but this little crossover board makes it much easier.

The board has a set of headers going in and a set going out. The TX and RX lines are swapped so you can connect it to a Bluetooth Mate and configure it without having to swap the pins coming from your FTDI.

JTAG Programmer and Debugger for LPC and ARM microcontrollers.

• Program LPC21xx, Atmel AT91, STMicroelectronics STR7 Parts, and other (not tested) ARM flash microcontrollers
• Uses ARM's standard 2x10 pin JTAG connector
• No external power supply required - all power is taken from the target board
• Compatible with Rowley's CrossConnect, IAR EWARM and GCC (OCD) software for programming, real time emulation, debugging, step by step program execution, breakpoints, memory dump etc. Everything a high priced emulator can do and more!
• IAR EWARM - unlimited assembler code size or in C with 16K limit for all LPC21xx ARM microcontrollers
• Works with free GCC C compiler and Insight tool chain and debugger.

Documents: ARM-JTAG.pdf, ARM JTAG Connector
Dimensions: 2x1.6" (50x40 mm) + 8" (20 cm) cable

In general, LPC21xx are very new parts. And for some unknown reason, Philips doesn't disclose how to program LPC21xx Flash via JTAG. This has delayed the development of third party IDEs. Perhaps Philips is having problems with the Flash programming and is going to change the protocol in future. This is currently why they force end users to use their bootloader IAP protocol. The only vendor so far to work around this is Rowley. They first load in RAM small own bootloader which then receives data from the JTAG interface and feeds the packets into IAP to write to Flash segments. This is current the easiest to use product for the LPC21xx parts.

• Jim Lynch's tutorial for setting up the free GCC/GNU tool chain. The example software is available here.
• GCC C compiler from Macraigor Systems. Works smoothly with ARM-JTAG but can't program Flash and user can compile debug programs in RAM then re-build for Flash and use Philips' RS232 bootloader.
• GNUARM another GCC toolchain from Arius.
• CrossWork for ARM (so far most recommended by us) C compiler and debuger from Rowley Associates, this is the easiest to use package we have tested, works smoothly with ARM-JTAG and programs both Flash and RAM on LPC21xx
• EWARM C compiler and debugger (free for assembly language, 16K limit for C) from IAR Systems. Can't program LPC21xx Flash, user can debug and program only in RAM, then re-build project and use Philips' ISP utility to load the program through RS232 bootloader. C-SPY driver for ARM-JTAG have some glitches on newer and faster computers and does several crashes before connect to target. It works fine on older and slower computers though. According to IAR, they are going to fix this to the end of February 2004.
• SwiftX software development system for the ARM family works with the ARM-JTAG for live interactive debugging of the Atmel AT91 ARM core family (using Atmel's EB40, EB40A, etc. development boards). Port for the ST ARM parts coming soon.

This custom-designed plastic wheel from Pololu has a rubber tire measuring 1.65" (42 mm) in diameter and is designed to fit the output shafts on our micro and mini metal gearmotors as well as the Solarbotics metal gear motors. Teeth on the hub optionally allow a reflectance sensor to be used for encoder feedback.

This rugged wheel is designed to fit securely on the output shafts of the micro and mini metal geramotors. These gearmotors should be mounted onto the side of the hub with the protruding teeth. The output shaft will slide into the socket easily at first but will achieve a snug fit when pressed through to the other edge of the hub.

The output shafts on the Solarbotics metal gear motors will also fit these wheels, but because they are shorter they will have to be mounted onto the other side of the wheel where the fit is tighter.

The Micro Metal Gearmotor Bracket Extended is specifically designed to work with this wheel. Please note that the non-extended version of our mounting bracket will not work well with this wheel.

Sold in pairs. You get two wheels.

This shield features the MSGEQ7 graphic equalizer display filter, the same IC used in the Colorganic Spectralizer kit. Two of these ICs allow you to split a stereo audio input into 7-bands (per channel) and read the amplitude of each using the ADC on your Arduino. The shield is populated with two 1/8" stereo jacks (like you would find on a pair of headphones). One serves as a stereo input and the other is a pass-through output which allows you to connect the Spectrum Shield in-line between your audio source and your stereo system without interruption. This shield can be used to create sound visualizers, detect patterns in music or add sound activation to your microcontroller projects.

This is a glass ferrule type fuse. It fits great with our 5mm fuse clips. The fuse is rated for 250VAC, up to 200mA. Fuses are pretty simple, if more than 200mA pass through the fuse, the small filament inside the fuse heats up and breaks (like a light bulb burning out). The circuit is then broken and hopefully your circuit is saved from molten destruction.

For smaller loads, you may want to checkout a PTC (aka resettable fuse) listed below. They handle less current (500mA) but can be set and reset many times without doing harm to your system.

This breakout board gives you a pretty slick interface for rotary input. Since rotary encoders turn continuously it can be difficult to imagine where in your range of values you might be at any given time. This board uses two 8-bit shift registers to control a circular LED bargraph which can be used to indicate the virtual position of a rotary encoder. The footprint for the encoder matches up with our illuminated rotary encoders for optimum 'blinky-ness'. The shift register inputs and rotary encoder lines are all broken out to standard 0.1" headers.

Note: This is the breakout board only, you will need to populate your own rotary encoder and circular LED bargraph. Both parts can be found in the related items below.

The Danger Shield mounts on top of your Arduino orArduino Pro and equips it with a variety of fun and useful inputs and outputs. The Danger Shield has so much potential; we can't wait to see what you're able to do with it! The shield's features include:

• Three linear slide potentiometers connected to the Arduino's analog pins 0 through 2.
• Red and yellow LEDs connected to digital pins 5 and 6 - PWM pins - so you can easily vary their brightness.
• Three momentary push buttons connected up to the Arduino's digital pins 10 through 12. Those lines will go low when the buttons are pressed.
• A photocell and a temperature sensor, both with analog outputs, are connected to the analog pins 3 and 4, respectively.
• An 8-bit shift register set up to control a blue 7-segment LED.
• Two buzzers - one is used, as you'd expect, as a speaker, the other is connected to analog pin 5 and can be used as a knock sensor.

This new version uses a different temperature sensor. This product comes as a kit of parts, which you'll have to solder into the included PCB. All parts are through-hole so it should go together relatively easily; but always check your component orientation before soldering!

The Joystick Shield sits on top of your Arduino and turns it into a simple controller. Five momentary push buttons (4+ joystick select button) and a two-axis thumb joystick gives your Arduino functionality on the level of old Nintendo controllers.

Please note: This is an older version of the PCB that does not have the prototyping area. The examples and assembly guides still apply. We're just trying to give these PCBs a happy home before we move on to the next revision.

The momentary push buttons are connected to Arduino digital pins 2-6; when pressed they will pull the pin low (utilizing the internal pull-ups of the Arduino). Vertical movement of the joystick will produce a proportional analog voltage on analog pin 0, likewise, horizontal movement of the joystick can be tracked on analog pin 1.

This product is only the Joystick Shield PCB - you'll need to purchase the buttons and joystick separately, and assemble the controller yourself. Here's what you'll need in addition to the shield:

• 4 x Momentary Push Button Switch - 12mm Square
• 1 x Thumb Joystick
• 1 x Mini Push Button Switch (breaks out Arduino's reset switch)
• 2 x 6-pin Arduino Stackable Header

The Maple board consists of the essentials: a fast processor with lots of peripherals. At the center of Maple is a 72MHz ARM Cortex M3 chip, providing the increased computational power desired by more advanced users. In the past, ARM processors were notoriously unfriendly in non-professional environments due to proprietary tool chains and unfamiliar instruction sets. Because of this, they were conspicuously absent from classrooms and hobbyists’ workbenches. Leaf aims to change this by providing an ARM tool-chain built from open source components and a programming environment that is intuitively easy to use. For those of us who love and are familiar with Arduino, Maple is offered in an Arduino-compatible format, complete with Arduino pin layouts and programming environment. In the future, a Cortex native version is available in order to take full advantage of this fantastic micro-controller. Learn More

This custom-designed plastic wheel has a rubber tire measuring 1.65" (42 mm) in diameter and is designed to fit the output shafts on our mini metal gearmotors as well as the Solarbotics metal gear motors. Teeth on the hub optionally allow a reflectance sensor to be used for encoder feedback.

This rugged wheel is designed to fit securely on the output shafts of the micro metal geramotors. These gearmotors should be mounted onto the side of the hub with the protruding teeth. The output shaft will slide into the socket easily at first but will achieve a snug fit when pressed through to the other edge of the hub.

The output shafts on the Solarbotics metal gear motors will also fit these wheels, but because they are shorter they will have to be mounted onto the other side of the wheel where the fit is tighter.

The Micro Metal Gearmotor Bracket Extended is specifically designed to work with this wheel. Please note that the non-extended version of our mounting bracket will not work well with this wheel.

Sold in pairs. You get two wheels.
