Flexible set : 1pcs RAMPS 1.4 Controller Board+ A4988 Stepstick Stepper Motor Driver Module with Heat Sink(Pack of 5 Pcs) on your Arduino-compatible MEGA shield for easy service, part replacement, upgrade-ability and expansion.
Each road stepper motors only need two IO ports.
RAMPS 1.4 expansion board as a driver expansion board, can be used for engraving machines, 3D printers.and It is a total of four slots, can drive four A4988 stepper motor.
Stepper motor wiring as follows: 2A, 2B is a group (red, green), 1A, 1B is a group (blue, yellow), if want to change direction, can be change the position of one group , for example 2A, 2B mutually exchanged.
Update High Quality Ramp Board by changing MOSFET: old MOSFET IC Model : PDF55N06 Specification：VDSS:60V ID:55A; New MOSFET IC model: HM60N06 Specification：VDSS:60V ID:60A; HM60N06 current up to 60A，More safety.
