The Leviathan Extension Board is a plug and play PCB that expands the feature set of the original Leviathan controller board. It adds:
- 2x Integrated TMC5160 stepper drivers.
- 2x Fan ports with flyback protection, 12V/24V selectable voltage, and tachometer inputs.
- 2x Thermistor ports with 2k2 ohm pullup resistors.
- 1x Piezo Buzzer
