Hovedkort med støtte for Klipper-firmware, for Voron 3D printere
LDO/Voron Leviathan Control Board er resultatet av et samarbeid mellom JNP og LDO etter ønske om å lage et hovedkort spesielt for Voron 3D printere.
Hovedkortet har dedikert plass for Raspberry Pi 3, 4, 5 eller Zero 2W (selges separat).
Målet med utviklingen av dette kortet var å lage et driftssikkert og holdbart hovedkort som ikke inneholder masse unyttige funksjoner, og her er kortet – med alle lovnader oppfylt.
