keyestudio RAMPS1.4A is used as driving shield for 3D printers, fully compatible with MEGA2560 control board and official RAMPS 1.4 .
It has total 5 slots for stepper motor drive module to drive 5-channel stepper motors. The slots are compatible with all kinds of drive modules like A4988DEV8825.
There are 3 jumper caps under each slot, which can be used to control the working subdivision of drive modules.
For example, if connect the A4988 and plug three jumpers, the subdivision port MS1、MS2 and MS3 of A4988 module are at active HIGH, so the A4988 module is in 16-subdivision working mode. But if unplug the three jumpers, MS1、MS2 and MS3 of A4988 module are at active LOW, so the A4988 module is in full-step working mode.
Furthermore, it is easy to stack it onto the MEGA 2560 control board, after burning the program, you can combine it with external devices to make your own 3D printer.
