3D Printer Motherboard Rumba Board Main Control Board 3D Printer Control Board

Basic parameters:
1. Using the same CPU as Arduino MEGA, Atmega2560 is used as the main control chip, and with high-performance USB chip CP2102, it can be compatible with all RAMPS related firmware
2. 5 temperature sensor interface inputs
3. All other pins are led out to facilitate more function expansion
4. With LCD expansion interface, you can connect Chinese LCD screen and SD expansion board to achieve offline printing
5. The servo gear expands the interface to facilitate the automatic leveling function
6. Support 6 A4988 16 subdivision stepper board
PWM DC output (heating tube, fan, etc.)
7. 6 outputs (1 high current, 3 currents, 2 low currents)
8. Drive with a high performance low conduction resistance Mos tube
9. Each output has an LED as an indication

Power supply:
1. Dual power supply design to avoid mutual influence (12V power supply is strongly recommended)
2. The hot bed part supports 11A current, 12V
3. Other parts of the circuit, 5A, 12V
4. In order to reduce the high temperature generated by the large current on the Mega Controller board, it is recommended to add a 12V cooling fan.
