## Description

The IOIO-OTG (pronounced "yo-yo-O-T-G") is a development board that lets Java developers add hardware I/O capabilities to Android or PC applications. A PIC24FJ256 microcontroller bridges your app to low-level peripherals including GPIO, PWM, ADC, I²C, SPI, and UART, all controllable through a Java library. The OTG (On-The-Go) design supports both USB host and device modes. When connected to an Android device, the board acts as a USB host and supplies charging current. When connected to a PC (Windows, Linux, or macOS), it presents as a virtual serial port and draws power from the host. Attach a USB Bluetooth dongle for wireless connectivity. Key Features USB OTG Support – Auto-detects host or device mode (manual override switch available) Java Control Library – Write hardware control code as a standard Java app Rich Peripheral Access – GPIO, PWM, ADC, I²C, SPI, and UART Cross-Platform – Works with Android, Windows, Linux, and macOS Bluetooth Ready – Connect a USB Bluetooth dongle for wireless serial LiPo Battery Connector – JST connector with adjustable charge current (trimpot) Field-Upgradeable Firmware – Update via the IOIODude application (no programmer needed) Ideal For Android hardware accessories and peripherals PC-based data acquisition and control Robotics with Java-based control software Rapid prototyping of USB-connected hardware Package Contents 1× IOIO-OTG Development Board (V2.2b) 1× USB Female-A to Micro-A OTG cable Resources Hookup Guide IOIO Wiki IOIODude Firmware Updater PIC24FJ256 Datasheet (PDF) Operating Modes Application Note (PDF) Schematic (PDF) Design Files (GitHub)
