DM183022 - 

The board has full pin break-out for easy wire wrap/proto-typing, 40 MHz operation, potentiometer connected to 10-bit A/D, analog input channel, temperature sensor, 8 LEDs, RS-232 port, and is serial bootloader ready. A 32 kHz crystal is included for real time clock demonstration.
This low-cost demo board is the ideal complement to the MPLAB® ICD 2 In Circuit Debugger to evaluate the performance of Microchip high-end 8-bit microcontrollers of the PIC18F series.
The board features a PIC18F8722 microcontroller, which is the superset of the entire 64- and 80-pin PIC18FXXXX general purpose family. A daughter board (mezzanine) is also part of the kit and allows different processors sharing the same pin out to be mounted and tested on the Explorer board.
The same connector allows MPLAB ICE 4000 (and via an extension MPLAB ICE 2000) real-time in-circuit emulators to be attached to the board.
