The circuit is the minimum that is around the chip: the miniDemoBoard is ultra simple, but as a basis for experimenting with embedded microcontrollers do not need anything else.
The board is small in size (58 x 39 mm or so), but it contains everything you need to run the PIC:
The scheme is the application of the chip embedded, with the possibility of a series of options:
Vdd/Vss can be conntected to the board by the breadboard's connector:
But the 'power can also arrive at the ICSP connector: the PICkit can deliver power to the connected circuit, within the limits specified by the manufacturer, can tap power from the USB connection and power circuits also quite complex.
Furthermore the connection ICSP / ICD with PICKit allows also to use the card as a support for stand-alone programming without the need to external power.
A 0.1 uF capacitor (C1, multilayer, 50 V, pitch 2.52 ") and an electrolyte (C2, 4.7 uF tantalum - aluminum or 10 uF - 10 V) work fine even if the cable between the card and power supply are not short .
It was expected to supply on-board because for ICSP / ICD is unnecessary and would be limiting in other applications the PIC operate between 2 V (LF) and 5 V and may be interesting to experiment with these possibilities.
Powering the breadboard
To power the breadboard, nothing better form UBS-12
