External reset button.

Two user-programmable buttons are connected to the microcontroller GP2 GP5 pin can be used as ordinary buttons use, or use as an external interrupt button.

A power indicator, two user-programmable LED

External 5V DC power connector (with the delivery of the USB power supply line, or downloader for power supply)

Power switch.

ICSP programming interface (which can be accessed K150 PICKIT2 PICKIT3 ICD2 ICD3 other tools).

Microcontroller IO port all use pin leads are easy to expand, to take all jumpers removed microcontroller IO port can be completely disconnected from the external circuit, do not extend the experiment more freely restriction original circuit board.
