Are you a Java developer looking to add advanced hardware I/O
capabilities to your Android or PC application? Well then the IOIO-OTG
is for you!

The IOIO-OTG (pronounced "yo-yo-O-T-G") is a development board
specially designed to do just that. It features a PIC microcontroller
which acts like a bridge that connects an app on your PC or Android
device to low-level peripherals like GPIO, PWM, ADC, I2C, SPI, and
UART. An app-level library helps you write control code for these low
level peripherals in the same way you'd write any other Java app!

What separates the IOIO-OTG from previous IOIO boards is the ability
to leverage the USB On-The-Go specification to connect as a host or an
accessory. There are several ways to connect the IOIO to your Java
app. If the app is running on your Android device, the IOIO-OTG will
act as a USB host and supply charging current to your device (meaning
the IOIO-OTG will need its own power source). If your app is running
on a Windows, Linux or OSX machine, the IOIO-OTG will assume device
mode and present itself as a virtual serial port. When in device mode,
the IOIO-OTG can be powered by the host! Connecting a USB Bluetooth
dongle will cause the IOIO-OTG to show up as a Bluetooth serial
connection so you can go wireless!

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. We're now shipping the
IOIO-OTG board loaded with the V4.00 bootloader and the V3.30
application firmware. New application firmware is frequently released,
and can be upgraded without needing a programmer using the IOIODude

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.
