Is there a wiring diagram available for the E-stop wiring? I would like to add an additional wireless E-stop.

Hi,

[Here’s a diagram](https://www.figma.com/file/UtZSjL0evK1SoussO7946I/Untitled?type=whiteboard&node-id=0%3A1&t=POjZi9rS6uebhrib-1) of the Wireless “soft” E-stop using a Kar-Tech wireless E-stop+receiver, a feather and 24V-5V converter. It plugs into the the CAN bus and uses a modified version of the [bumpers/code.py example](https://github.com/farm-ng/amiga-dev-kit/blob/main/circuitpy/examples/bumpers/code.py). This allows you to send an EstopRequest to safely stop/brake the robot. I’ll provide more documentation if you’d like to duplicate this setup.

Alternatively, you can open and close the E-stop circuit using pin 2/3 from the bulkhead M8 connector (after removing the jumper). This is not recommended because this turns the motor controllers off and the robot will roll freely.
