chipKIT™ Uno32™ Jumper Settings Revision: May 23, 2011 1300 NE Henley Court, Suite 3 Pullman, WA 99163 (509) 334 6306 Voice | (509) 334 6300 Fax The chipKIT™ Development Platforms are based off the PIC32 Microcontroller. These are 32-bit products that bring unprecedented features to the Arduino™ community. In order to maintain compatibility with existing hardware/software while maintaining user accessibility to these advanced features, additional jumpers and row headers are provided. This document describes the functionality of the jumpers listed in figure 1. Figure 1: chipKIT™ UNO32 Jumpers Jumper Function JP2 POWER SELECT: Used to connect/bypass on-board 5V regulator when using a power supply connected to J4 J4 supply is regulated (i.e. 5V will be present on 5V pin) J4 supply bypasses regulator (i.e. Supply voltage will be present on 5V pin) Note: A 3.3V on-board regulator will always be enable regardless of JP2 settings to protect the PIC32 MCU Not sure what this does? Play it safe and keep JP2 on the two right-most pins. (i.e. J4 supply is regulated) Doc: DSD-0000302 page 1 of 2 Copyright Digilent, Inc. All rights reserved.

Pin 10 configured as a Digital Input/Output JP5/JP7 Pin 10 configured as a PWM output SPI SELECT: Used to configure the chipKIT™ as either a Master or Slave when using the SPI (Serial Peripheral Interface). The chipKIT™ board can be connected to another device or even another chipKIT™ through the SPI connector (J8). chipKIT™ configured as a SPI Master chipKIT™ configured as a SPI Slave For more information on SPI, please visit Wikipedia’s SPI page at: http://en.wikipedia.org/wiki/Serial_Peripheral_Interface_Bus#Mode_Numbers JP6/JP8 I2C/ANALOG PIN SELECT: Used to configure A4 and A5 for functionality as an Analog input or to be used as I2C communication pins. A4 and A5 on J7 are configured to be used as analog inputs A4 and A5 are configured to be used as I2C communication lines (A4 – SDA, A5 – SCL ) For more information on I2C, please visit Wikipedia’s I2C page at: http://en.wikipedia.org/wiki/I2C www.digilentinc.com page 2 of 2 Copyright Digilent, Inc.
