IOIO OTG Android IO PIC Microcontroller

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! USB-OTG dual-role (host, device). Input voltage: 5V-15V, from external source or through USB (when connected to a computer). Output voltage: 5V, up to 3A (!), 3.3V, up to 500mA. 46 I/O pins (digital I/O), built-in pull-ups / pull-downs / open-drain on all pins. 16 Analog inputs. 9 PWM (for driving servos, DC motors, dimming LEDs, etc). 4 UART. 3 TWI (I2C, SMBUS). 3 SPI. 6 Pulse Input (precise pulse-width / frequency measurement). USB current limiting when acting as USB host (useful in Android mode). Switch for forcing host mode (for using non-standard USB cables, which are more common than the standard ones...) On-board LED under user control.
