The IOIO-OTG is a board which allows you to quickly and easily interface electronic circuits to an Android device or a PC: Connect the IOIO-OTG to the Android / PC using USB or Bluetooth. Power the IOIO-OTG (not required if operating in USB device mode, see below).
Connect your circuits to any of the 46 I/O pins available on the IOIO-OTG. You can power your circuits off of the IOIO-OTG too. Write a Java program to control the I/O pins, using a high-level API using the provided libraries.
A switch on the board can be used to force the IOIO-OTG into host mode, but most of the time the board can be left in ‘auto’ mode and it will detect its role in the connection. New application firmware is frequently released and can be upgraded without needing a programmer using the IOIODude application. Additionally, this version of the IOIO-OTG has corrected the IC power failure issue due to the onboard switch voltage regulator failing as well as adding a missing decoupling cap on the AVIN pin. This new IOIO-OTG has fixed the problems that plagued the previous version making it a true vision of how the board is intended! You can find out more about these updates
The board includes a JST connector for attaching a LiPo battery and there are several pin headers broken out for voltage and ground access. A trimpot on the board allows you to adjust the charge current used when the IOIO-OTG is acting as a host. A USB-A to micro-A OTG cable is included which will let you connect your android device to the micro-USB port on the board using the cable that came with your Android device.
