grblHAL Teensy 4.1 Breakout Board
This is a breakout board that along with grblHAL firmware and a Teensy 4.1 becomes a full fledged CNC motion controller for devices like routers, mills, lasers and lathes. Using grblHAL, it forms the basis of a motion control system with advanced features that you would have to pay multi-hundreds of dollars to get with other products.
