I want to add limit switches can someone tell me what kind i need. i dont really want to add external power in i dont have to.
Thanks
These are the sensors I ordered for mine (Amazon.com). I’m not sure how you could do this without external power as the sensors I’ve seen are 6 - 36V, and I think you can only get 3.3V from the power supply inside the Buildbotics controller.
I followed this thread for getting mine up and running: Proximity sensor power on X-50
