Archiving hint: In late summer 2023, Github started to enforce 2FA (Two Factor
Authentication), so I had to archive it before losing control
over it. See also https://github.com/Traumflug/Generation_7_Electronics/issues/28

Design Goals
- PCB easily to manufacture on a RepRap.
- All parts on one board. Except for the Opto Endstops, of course.
- Enough components to run a Mendel or Huxley with extruder and heated bed.
- Easy to set up. For example, this would include an USB port.
- Well available and cheap parts.
- Based on the ATmega644.
- Well suited for community driven development.
Features
- Single board solution.
- Single sided PCB.
- Pololu stepper drivers, exchangeable.
- 4x stepper motor drivers with 1/16 microstepping.
- TODO: on-board USB-RS232 converter.
- Integrated hardware for driving one extruder (stepper, heater and thermistor).
- Integrated hardware for a heated bed (heater, thermistor).
- Integrated hardware for driving a fan.
- Ready to be hooked up on a generic PC power supply unit (PSU).
- Use of standard connectors.
- Debug LEDs for power, Fan and both heater outputs.
- Can turn PSU on and off in software.
- Reset button.
