„The chipKIT™ Max32™ combines compatibility with the popular Arduino™ open source hardware prototyping platform with the performance of the Microchip PIC32 microcontroller. The Max32 is the same form factor as the Arduino Mega board and is compatible with standard Arduino™ shields as well as larger shields for use with the Mega boards. It features a USB serial port interface for connection to the IDE and can be powered via USB or an external power supply.
The Max32 board takes advantage of the powerful PIC32MX795F512 microcontroller. This microcontroller features a 32-bit MIPS processor core running at 80Mhz, 512K of flash program memory and 128K of SRAM data memory. In addition, the processor provides a USB 2 OTG controller, 10/100 Ethernet MAC and dual CAN controllers that can be accessed via add-on I/O shields.
The Max32 can be programmed using an environment based on the original Arduino™ IDE modified to support PIC32. In addition, the Max32 is fully compatible with the advanced Microchip MPLAB development environment and the PICKit3 in-system programmer/debugger.
