I’ve started sourcing parts for the Lowrider 2. When it come to the controller Id like to have Bluetooth or wifi connection. So I’ve hunted around and found Bart Dring’s completely open source Esp32 based board .
Nothing I’ve found matches it cost-wise. Gerber file is provided and the Esp32 wifi/ bluetooth SOC’s cost around $7. But I’d like to hear from anyone who may be using it. And I’d especially like to hear about any dramas involved with setting up Grbl and configuration on the Lowrider.
