Final hardware assembly & connection design

[ololonly]

• Document Mara X connector pinout
• Research power supply options from machine connector
• Design/select appropriate connector for ESP32 board
• Create wiring diagram
• Test power delivery from machine
• Document assembly instructions with photos
• (Optional) Design 3D-printed case/mount

Goal: Plug-and-play connection to Mara X

Power delivery from the machine seems to be problematic. There is 12v power source, but it's occupied by another connector.
It's easier to use external adapter
