Overview
The chipKIT WF32 is based on the popular Arduino™ open-source hardware prototyping platform and adds the
performance of the Microchip PIC32 microcontroller. The WF32 is the first board from Digilent to have a WiFi
MRF24 and SD card on the board both with dedicated signals. The WF32 board takes advantage of the powerful
PIC32MX695F512L microcontroller. This microcontroller features a 32-bit MIPS processor core running at 80Mhz,
512K of flash program memory, and 128K of SRAM data memory.
The WF32 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. The WF32 features a USB serial port interface for connection to the MPIDE and
can be powered via USB or by an external power supply. In addition, the WF32 is fully compatible with the
advanced Microchip MPLAB
®
IDE and works with all MPLAB compatible in-system programmer/debuggers, such as
the Microchip PICkit™3 or the Digilent chipKIT PGM. The WF32 is easy to use and suitable for both beginners and
advanced users experimenting with electronics and embedded control systems.
