TheNU32TheNU32isaninexpensive60-pinDIP-compatibledevelopmentboard for the 64-pin surface mount PIC32MX795F512H. Itsprimary purpose is to break out the pins of the PIC32. It alsoincludes an FTDI FT231X USB-to-UART chip that allows simpleserial port communication over a USB cable with a programrunning on the host computer (e.g., a terminal emulator,MATLAB,Python,etc.). Theboard canbepowered standalonebythe included6Vwalladapterorbythehost’sUSBport.
