• The Heatsink goes on the Motor driver !in the real picture its on the wrong chip!

• The Pico MMU is connected via USB or CAN BUS to the Raspberry pi (Klipper)

• You will need an (Printer) board that supports Klipper

• Marlin Firmware is not supported

• If you own a standard Ender (Marlin Firmware) 3, S1, S1 Pro, etc. , you need to flash the control board with Klipper and use a Raspberry Pi running a Klipper firmware with Mainsail or Fluidd.
