- Elecrow Arduino CNC Shield V3.51
- Includes Noise Filters on all endstops and the probing pin
- Is compatible with GRBL 0.9 and offers 4-Axis support
- Has 2 x End stops for each axis
- Uses removable Pololu A4988 compatible stepper drivers
The Elecrow Arduino CNC Shield V3.51 - GRBL v0.9 Compatible is a simple Arduino CNC shield kit (Arduino Extension Board) with the following features: New with Version 3.51 Added circuitry for End-Stop and Probe signal filtering. This eliminates false triggers and makes it possible to use non-shielded cable for end-stops/probes.

Bigger Solder pads make it easier to assemble. Probe pin labels have been updated to make it easier to install a probe.
