I²CDriver is an easy-to-use, open source tool for controlling I²C devices. It works with Windows, Mac, and Linux, and has a built-in color screen that shows a live “dashboard” of all the I²C activity. It uses a standard FTDI USB serial chip to talk to the PC, so no special drivers need to be installed. The board includes a separate 3.3 V supply with voltage and current monitoring.
Maximum power out current: up to 470 mA Device current: up to 25 mA Dimensions: 61 mm x 49 mm x 6 mm Computer interface: USB 2.0, micro USB connector
