3D Printer Main Control Board MEGA 2560 Motherboard Ramps 1.4

• 2560 and ramps1.4 collection on a board, solved the ramps1.4 combination interface trival, easily out of order.
•  can replace the motor driver, support 4988 drivers and 8825 drivers.
• circuit board USES the high quality 4 layer board, and the thermal optimization; Ramps is 2 layer board.
• using high quality MOSFET tube, the effect of heat dispelling is better.
• using special power supply chip, support the 12 v and 24 v power input, solve the problem of Ramps voltage conversion chip fever.
• can accept 24 v input, under the same system power can reduce the current hot bed to 1/4, effectively solve the problem of hot bed MOS tube heating.
• firmware, you can use open source firmware Marlin, configuration and ramps1.4 are exactly the same, can be directly replace ramps1.4.
• can be directly connected Ramps1.4, 2004 LCD control panel and the LCD panel (12864).
• reserved motor pulse and direction of output port, convenient external large current to external large current (e.g., 2 a, 5 a) motor drive circuit.
• retain Ramps1.4 Servos, AUX 1, AUX - 2 interface, provide 3 5 v output, 3 12 v output interface.
