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.
