The chipKIT™ uC32 development board is an Arduino-style platform for developing microcontroller-based applications. It uses the chipKIT-core™ and Arduino IDE, for compatibility with existing code examples, tutorials and resources. chipKIT™ uC32 is also pin-compatible with many Arduino shields that can operate at 3.3V.

¶Useful Board Pins

¶LEDs

¶Analog Inputs

¶Serial Objects

¶I2C

I2C SCK pin is Digial 46, and SDA is Digital 45.

The pins are shared with analong pins A4 and A5 and must be selected using jumpers JP6 and JP8. For JP6 and JP8: Short Pins 1&2 for Analog input mode adn Pins 2&3 for I2C mode.

¶SPI

SPI SS is Digital 10, MOSI is Digital 11, MISO is Digital 12, CLK is Digital 13.

Jumpers JP5 and JP7 are used to select whether the uC32 operates as a Master (transmit on MOSI, receive on MISO) or a Slave (transmit on MISO, receive on MOSI) device.

¶Pinout Table

Quick reference: There are two user LEDs (Pin 11, Pin 43), and 12 analog inputs (Pin 14 - Pin 25, A0 - A11). All 47 are usable as GPIO, however some may be in use when used with the Arduino platform.
