Campaign is Live!

The campaign for I²CMini is now live! Just like its bigger version I²CDriver, I²CMini is a tool for controlling I²C devices over USB. Together they make an ideal workflow: you can debug and develop with I²CDriver, and deploy with I²CMini.

I²CMini came from a supporter suggestion during the I²CDriver campaign. The idea of a "headless" I²CDriver started making sense to me as a I started to use I²CDriver in places where a display wasn’t needed. The I²CMini a a tiny interface between USB and I²C - perfect if you build IoT, sensor or other lightweight embedded I²C networks.

Just like I²CDriver and SPIDriver, the I²CMini is about helping makers make things. Thanks for your support.

I'm dedicated to building useful hardware and software, particularly where embedded systems meet graphics and imaging. Probably my best known public projects are the Gameduino series of game accessory boards, and the J1 CPU. I have benefited immensely from Open Source hardware and software, so I try to open source as much as I can.
