What is it?

You have a RAMPS, RUMBA, or other CNC board that supports A4988 stepper drivers (limit 1.5 amps). You want to connect to external high amp and/or high voltage drivers to the 5v30ma pins on your board. This PCB is shaped like an A4988 and provides convenient screw terminals to connect to your high current driver. Say NO to loose wiring! Say YES to Sir RAMPSalot.

Board requires 3.5mm terminal blocks and .1" breakaway male headers, not included.

Why did you make it?

To run a high torque DIY CNC machine with open source electronics.

What makes it special?

It's made with 5% more sass than the next leading brand.
