Redesigned JDM programmer board

Significant improvements against the original design¶

• Support for both PIC18F452 and PIC16F87x using R4 pull-down resistor.

• Only one single bridge: NO wires under the board.

• Integrated external PSU support.

First let’s take a look at the schematic:

This is how the board looks like after about 10 hours of hard work:
