  • A note of caution when using this programmer to program devices in-circuit… VDD (5V) is only generated during actual programming. Otherwise voltage on the VDD header pin is close to ground. If you try to connect this programmer to a live board it will essentially short the board’s 5V to ground, which, depending on the design, can lead to problems. Microchip’s PICKit2 programmer doesn’t have this issue and, in my experience, can program boards that are powered on.

No public wish lists :(
