Converters

The TSL235R light-to-frequency converter outputs a square wave (50% duty cycle) with frequency directly proportional to light intensity (irradiance). The device has been temperature compensated for the ultraviolet-to-visible light range of 320 nm to 700 nm and responds over the light range of 320 nm to 1050 nm.

The TSL235R can be powered at anywhere between 2.7 and 5.5V, and will typically pull about 2mA of current. It comes in a simple, 3-pin through hole package. No external components are necessary to use the converter, and the digital output allows direct interface to a microcontroller or other logic circuitry.

Features:

• High-resolution conversion of light intensity to frequency with no external components
• Communicates directly with a microcontroller
• Compact three-leaded clear-plastic package
• Single-supply operation down to 2.7 V
• Nonlinearity error typically 0.2% at 100kHz
• Stable 150 ppm/°C temperature coefficient
• Single-supply operation

• CE/FCC/Rohs Compliant

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. 

Specification

• Voltage: 5V

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)
