In the top left of the schematic is the 25LC256 EEPROM. Here is a link to a PDF of the schematic: PDF Schematic Knowing this – I decided to see what I could do to remove the circuitry I didn’t need, yet still have a functioning programmer/debugger.Īfter a little research and looking at what Microchip had done with their starter kits, I arrived at the following schematic, which is based on their Pickit On-Board: ![]() I also have no real need for programming on the go, or even to provide power to the target MCU to program. For instance – I primarily use the newer 3.3V PIC32 processors, so I really don’t need the ability to alter the voltage like the standard Pickit 3 can. It works well, but I have often wondered just how little of its circuitry was needed to program and debug the boards I make. Previously, I made a Pickit 3 clone – (See previous Blog Post).
