Converters

5V Regulator Module for Arduino is a small board that can power your Arduino board.

It provides 5V to your Arduino board with a 1100 mAh Li-Ion battery (included). Note:You must charge the battery around 13h. at first time.

If you've ever tried to connect a 3.3V device to a 5V system, you know what a challenge it can be. The SparkFun logic level converter is a small device that safely steps down 5V signals to 3.3V and steps up 3.3V to 5V. This level converter also works with 2.8V and 1.8V devices. Each level converter has the capability of converting 4 pins on the high side to 4 pins on the low side. Two inputs and two outputs are provided for each side.

Bread board friendly! Can be used with normal serial, I2C, SPI, and any other digital signal. Does not work with an analog signal.

The level converter is very easy to use. The board needs to be powered from the two voltages sources (high voltage and low voltage) that your system is using. High voltage (5V for example) to the 'HV' pin, low voltage (2.8V for example) to 'LV', and ground from the system to the 'GND' pin.

Pins are labeled as Inputs and Outputs. These are relative to the board. A digital one going into the RXI pin on the 5V side will show up on the RXO pin on the 3.3V side as 3.3V. A digital one going into the TXI pin on the 3.3V side will show up on the TXO pin on the 5V side as 5V.

This is a simple adapter which allows you to charge your iPad, iPhone, or iPod from a mini USB cable. It's as simple as that! It works with 3rd gen iPods, iPhone 3Gs, and pretty much any Apple product which has an 'i' in front of the name that uses this connector. But keep in mind, this is JUST A CHARGER and will NOT allow you to access data from your computer or make a USB data connection.  It's just a charger. What you see is what you get. This does not come with a cable or an 'i' product.

This is a simple USB serial interface to mate with the Nike+iPhone/iPad/iPod product. Use this breakout board to send and receive serial commands to the receiver and listen for individual foot pods. This will allow easy creation of proximity based projects and running/workout research. VCC (3.3V), ground, and iPhone/iPad/iPod TX and RX are brought out to a standard header so that you can connect this board to a microcontroller.

Don't forget to checkout the original tutorial!

We provide a simple example VB program that demonstrates how to initialize the receiver to listen for all foot pods in range and display the raw data including foot pod IDs. Any receiver can hear any foot pod - they don't have to be mated in any way.

It turns out the foot pod will activate with minimal movement. We really want to attach these to our cats and make an ID controlled cat-door-lock system. 'Are you Carlos? No? You can't come in.'

Once you've hacked everything, why not go out in the garage and hack your car? This cable allows you to access the pins on your car's OBDII connector. It has an OBDII connector on one end and a DB9 female serial connector on the other.  The overall length of the cable is 5'.

Note: This cable is not meant to be plugged directly into a computer's serial port. It is meant to plug into some sort of hardware interface.

This is a high quality, low cost, small, and easy to use USB to RS232 converter. Device uses the Prolific IC PL-2303 and supports baud rates up to 1Mbps. Driver support for Windows, Mac, and Linux RedHat.

This converter plugs directly into your USB port on your computer and even comes with a small extension cable and CD for drivers.

This is the newest revision and fixes issues with the last board. This breakout board pairs an SP3485 RS-485 transceiver with an FT232RL USB UART IC to convert a USB stream to RS-485. The SP3485 is a half-duplex transceiver, so it can only communicate one way at a time, but it can reach transmission speeds of up to 10Mbps.

Dimensions: 1.55x0.9 inches

This USB to TTL converter combine the USB-232-1 (USB to Single RS232 Adapter) and TTL-232-1 (Port-powered RS232/TTL converter) allows you to convert USB to TTL/CMOS compatible levels and vice versa.

It can be used to set up APC220 RF wireless module. 

It can be used as STC microcontroller program downloader. 

The PCB color may vary and not the same as shown in the picture.

This is a basic breakout board for the FTDI FT232RL USB to serial IC. The pinout of this board matches the FTDI cable to work with official Arduino and cloned 3.3V Arduino boards. It can also be used for general serial applications. The major difference with this board is that it brings out the DTR pin as opposed to the RTS pin of the FTDI cable. The DTR pin allows an Arduino target to auto-reset when a new Sketch is downloaded. This is a really nice feature to have and allows a sketch to be downloaded without having to hit the reset button. This board will auto reset any Arduino board that has the reset pin brought out to a 6-pin connector.

Specification

• 3.3/5V output(switchable via Jumpers)
