Feature

●The expansion board can be used as a drive expansion board for engraving machines, 3D printers, etc. There is a total of 4 steps of the stepper motor drive module slot. (Note that this board does not include the A4988 stepper motor drive module, which can be purchased separately in this shop)
●It can drive 4 channels without entering the motor, and each stepping motor only needs 2 IO ports. That is to say, 6 IO ports can manage 3 stepping motors very well. It is very convenient to use and bid farewell to the tradition. Stepper motor operation is cumbersome.
●0.9 compatible. GRBL (open source firmware that runs on an uno that turns the G-code commands into stepper 37signals)PWM Spindle and direction pins.
●4-Axis support (X, Y, Z, A-Can duplicate X, Y Z, or do a full 4th axis with custom firmware using pins D12 and D13)2 x End stops for each axis (6 in total)
●Coolant enable,Compact design.


Description

Specifications:
Uses removable A4988 or DRV8825 compatible stepper drivers
Jumpers to set the Micro-Stepping for the stepper. (some drivers like the DRV8825 can do up to 1 / 32 micro-stepping)
Stepper Motors can be connected with pin Molex connectors or soldered 4 in place
Runs on 12-36v DC. (at the moment only the DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the.)
