For the last few years, [Ytai] has been working on the IOIO, a device that connects your Android devices to the other homebrew peripherals. There’s a new version of this really cool board out now that includes a few much-needed features like USB-OTG and a lower component cost that is passed on in savings to you.
A few months ago, our own [Mike Szczys] caught a glimpse of this new IOIO board. It’s the same size as the previous revision, but with USB-OTG, the new IOIO can be a master when connected to a phone, or a slave when connected to a PC.
In addition to USB-OTG, [Ytai] improved the power regulation circuit, and even went so far as to refuse royalties to the board to get the costs down. It’s currently available at Sparkfun for $40.
[Ytai] says he’s working on a few software upgrades to the IOIO, including making capacitive sensing a possibility and including support for stepper motors and controllers. There’s also support for the Raspberry Pi coming up, but we’re just glad [Ytai] managed to put a yo-yo graphic on the bottom silkscreen. Finally, and hopefully, everyone will know how to pronounce IOIO.
