B Overview The chipKIT uC32 is based on the popular Arduino open-source hardware prototyping platform and adds the performance of the Microchip PIC32 microcontroller. The uC32 is easy to use and suitable for both beginners and advanced users experimenting with electronics and embedded control systems. The uC32 is the same form factor as the Arduino Uno board and is compatible with Arduino shields. It features a USB serial port interface for connection to the IDE and can be powered via USB or an external power supply. The uC32 board takes advantage of the powerful PIC32MX340F512 microcontroller, which features a 32-bit MIPS processor core running at 80 MHz, 512K of flash program memory, and 32K of SRAM data memory. Features include: Microchip PIC32MX340F512H microcontroller (80 MHz 32-bit MIPS, 512K Flash, 32K SRAM) Compatible with many existing Arduino code samples and other resources Arduino Uno form factor Compatible with many Arduino shields 43 available I/O pins Two user LEDs PC connection uses a USB A > mini B cable (not included) 12 analog inputs 3.3V operating voltage 80 MHz operating frequency 75mA typical operating current 7V to 15V input voltage (recommended) 20V input voltage (maximum) 0V to 3.3V analog input voltage range The chipKIT uC32 board. +/-18mA DC current per pin The uC32 can be programmed using the Multi-Platform Integrated Development Environment (MPIDE), an environment based on the original Arduino IDE modified to support PIC32. It contains everything needed to start developing embedded applications. In addition, the uC32 is fully compatible with the advanced Microchip MPLAB IDE and the PICkit 3 in-system programmer/debugger. 2 The uC32 provides 43 I/O pins that support a number of peripheral functions, such as UART, SPI, and I C ports and pulse width modulated outputs. Twelve of the I/O pins can be used as analog inputs or as digital inputs and outputs. Copyright Digilent, Inc. All rights reserved.

USB Connector for USB Serial Converter This connects to a USB port on the PC to provide the communications port for the MPIDE to talk to the uC32 board. This can also be used to power the uC32 board when connected to the PC. 2. JP3 Microchip Debug Tool Connector This connector is used to connect Microchip programmer/debugger tools, such as the PICkit 3. This allows the uC32 board to be used as a traditional microcontroller development board using the Microchip MPLAB IDE. 3. J4 External Power Connector This is a 5.5mm x 2.1mm barrel connector used to power the uC32 board from an external power supply. It is wired with the center terminal as the positive supply voltage. The power supply voltage must be in the range 7V to 15V. 4. Power Supply 3.3V Regulator Voltage regulator for the 3.3V power supply. This power supply can provide up to 500mA of current.
