UEXT connector which allows many existing modules like RF, ZIGBEE, GSM, GPS to be connected
USB OTG functionality on mini USB connector
All PIC ports available on 0.1" connectors
mini ICSP connector 0.05"step. If you do not want to use Pinguino IDE and you want to program this board with a PIC-ICD2-POCKET or PIC-KIT3, you should use also a PIC-ICSP converter board, the same applies for Microchip programmers.
Do not use the "programmer-to-go" button when there is no image on the OLIMEX PIC-KIT3 or MICROCHIP PIC-KIT3 because that might put your microcontroller in an irrecoverable state. We have tested the mentioned scenario and we can confirm it destroys PIC32 chips (using both our and the original Microchip PICKIT3). We don't take responsibility if you break your chip that way.
