Frequently asked questions
Is it compatible with RAMPS-based firmware?
The board uses a RAMPS 1.4 pin-compatible layout, so firmware configured for RAMPS 1.4, such as Marlin, is commonly used. Verify the pin definitions in your firmware before flashing.
What power supply do I need?
The board accepts 12 or 24V DC. Size the supply for your hotend and heated bed loads, keeping in mind the bed can draw up to 10A.
