Arduino Uno / GRBL to HobbyCNC PRO Shield
Easy-to-assemble shield to simplify connection from an Arduino Uno running GRBL directly to a HobbyCNC PRO 3 or 4 Axis driver board.
No breakout board, super-simple wiring, opto-isolated inputs.
(Not included: Arduino UNO, GRBL or HobbyCNC PRO)
Available on backorder
Easy, one-cable connection to the HobbyCNC PRO 3 or 4 axis stepper motor driver board.
Kit is quick and easy to assemble. Greatly reduces wiring complexity. 5 opto-isolated inputs.
4th axis can be 'mirrored' from any of the other three axis.
Manual includes complete schematics specifically for the hacker!
