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.
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.
The uC32 provides 43 I/O pins that support a number of peripheral functions, such as UART, SPI, and I
2
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.
