Expansion Board
Non-returnable
BD 9.500
This expansion board as a driver expansion board can be used for engraving machines, 3D printers. It is a total of four slots, can drive four A4988 or DRV8825 stepper motor driver, 4-axis Arduino CNC Shield v3. Each road stepper motors only need two I0 ports. In other words, six 10 ports can be well managed three stepper motors. Very convenient to use.
Specifications:
1. Latest Arduino CNC Shield Version 3.10
2. GRBL 0.9 compatible. (Open source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals)
3. PWM Spindle and direction pins
4. 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)
5. 2 x End stops for each axis (6 in total)

Features
1. Coolant enable
2. Uses removable Pololu A4988 compatible stepper drivers. (A4988. DRV8825, and others) (Not Inciuded)
3. jumpers to set the Micro-Stepping for the stepper drivers. (Some drivers like the DRV8825 can do up to 1/32 micro-stepping)
4. Compact design.
5. Stepper Motors can be connected with 4 pin Molex connectors or soldered in place.
6. Runs on 12-36V DC. (At the moment only the Pololu DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board.)
7. Please note that this is an unassembled ktand neecs soldering.
8. * Jumpers color may vary depending on the available stock.
