Motherboard Rumba Mpu Rumba Optimized Version 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 firmware2. 5 temperature sensor interface inputs3. All other pins are led out to facilitate more function expansion4. with LCD expansion interface, you can connect Chinese LCD screen and SD expansion board to achieve offline printingThe servo gear expands the interface to facilitate the automatic leveling functionSupport 6 A4988 16 subdivision stepper boardPWM DC output (heating tube, fan, etc.)6 outputs (1 high current, 3 currents, 2 low currents)Drive with a high performance low conduction resistance Mos tubeEach output has an LED as an indicationPower supply:1. Dual power supply design to avoid mutual influence (12V power supply is strongly recommended)2. The hot bed part supports 11A current, 12V3. Other parts of the circuit, 5A, 12V4. 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.Material: PC+MetalColor as shownPackage Contents:1 x Motherboard1 x CableOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
