B 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. Microchip PIC32MX695F512L microcontroller (80 Mhz 32-bit MIPS, 512K Flash, 128K SRAM) Microchip MRF24WG0MA WiFi module Micro SD card connector USB 2.0 OTG controller with A and micro-AB connectors 43 available I/O pins four user LEDs PC connection uses a USB A > mini B cable (not included) 12 analog inputs 3.3V operating voltage 80Mhz operating frequency 7V to 15V input voltage (recommended) 30V input voltage (maximum) 0V to 3.3V analog input voltage range The chipKIT WF32 board. High efficiency, switching 3.3V power supply providing low power operation 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 PICkit3 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. Copyright Digilent, Inc. All rights reserved.
