Before I start soldering, let me gather all requirements in one place so the design is as polished as possible.
- Ideally, only one side of Teensy's pins should be used - right now, most of the programmer's pins are located on just one side of the Teensy board. There are two pins on the other side, though:
- PIN 13
- Microcontroller socket should be a part of the programmer board - in case the device doesn't have the programmer interface (programming is done by removing the chip), it should be possible to connect programmed chips directly on top of the programmer board.
- The board should have the ATtiny85 programming interface - 6 pins will be enough.
- The board should be as compact as possible - that goes without saying.
