The 2560 and for ramps1.4 are assembled on the board to solve the complex interface of the for Ramps1.4 interface and the problem of easy failure.
Replaceable motor drive, support 4988 drive and 8825 drive, TMC2100 drive, s109 drive.
An external drive signal is reserved to connect an external drive to drive the 57, 86 motor.
High quality MOSFET tube for better heat dissipation and long-term stability.
The special power chip is used to support the 12V-24V power input, which solves the problem that the Ramps voltage conversion chip generates heat and the power supply is insufficient.
