CR-10 Model Support Notes (Read this BEFORE buying for a CR-10 Series)CR-10 (Regular, Mini, S4 S5)

• MOSFET needed for the bed if your machine does not already have one (addon above)

CR-10S (Regular, Mini, S4 S5)

• Needs Creality Dual Cable LCD Adapter Board if you do not have the EXP3 header on your LCD.
• If you have the EXP3 header on your LCD use 1 cable to connect from the EXP3 to our board and you will then not need the dual adapter board.
• MOSFET needed for the bed if your machine does not already have one (Found here)
• Does NOT work with Touch Screen Models

Important Information

• Make sure to have an active cooling fan over the board to keep it cool. The Trinamic drivers run warmer than boards with the “standard” (aka 4988 series) drivers.
• On some machines, the EMI filter board addon is required, specifically Ender 5 machines.
