I have some confusion while studying the schematic for the project, USB PIC Programmer : PICKit2. What purpose does R13 (2k7) serve? It is connected to GND in parallel with VDD as depicted in the schematic. Does it act as a voltage divider? I will really appreciate if you kindly clear my confusion.
Also the PICKit2 zip package does not contain the Eagle schematic and board. Is it possible for you to kindly send them?
2.7K is the bleeder resistor to discharge capacitors when the programmer is unplugged. It will prevent unintentional “Unrecognized Device” error by ensuring proper Power On Reset when you plug in next time.
