Overview
ChipKIT MX3 is the new name for Cerebot MX3. This board retains all functionality of the Cerebot MX3.
The ChipKIT MX3 is a microcontroller development board based on the Microchip PIC32MX320F128H, a member
of the 32-bit PIC32 microcontroller family. It is compatible with Digilent’s line of Pmod™ peripheral modules, and is
suitable for use with the Microchip MPLAB
®
IDE tools. The ChipKIT MX3 is also compatible for use with the
chipKIT™ MPIDE development environment. ChipKIT MPIDE is a PIC32 based system compatible with many existing
Arduino™ code examples, reference materials, and other resources.
The ChipKIT MX3 is designed to be easy to use and suitable for use by anyone from beginners to advanced users
for experimenting with electronics and embedded control systems. It is intended to be used with either the Multi-
Platform IDE, (modified Arduino IDE), MPIDE, or the Microchip MPLAB IDE. The kit contains everything needed to
start developing embedded applications using the MPIDE. In order to use the MPLAB IDE, an additional
programming/debugging device, such as a Microchip PICkit3 is required.
The ChipKIT MX3 provides 42 I/O pins that support a number of peripheral functions, such as UART, SPI, and I
2
C™
ports, as well as five pulse width modulated outputs and five external interrupt inputs. Eleven of the I/O pins can
be used as analog inputs in addition to their use as digital inputs and outputs.
The ChipKIT MX3 can be powered via USB, an external power supply that may be either an AC-DC power adapter,
or batteries.
1 Programming Tools
The ChipKIT MX3 is designed to be used with either the Multi-Platform IDE (MPIDE), the development software
environment used with the chipKIT™ system, or as a more traditional microcontroller development platform using
the Microchip MPLAB
®
IDE and development tools. The ChipKIT MX3 if fully compatible with Microchip
development tools that support the PIC32 family of microcontrollers.
