| 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 80 MHz, 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.
