I made some updates to the schematic and then designed the PCB. I found footprints to Adafruits magnetic pogo pins, which I think I’ll be using to attach components and keep it modular. The PSU will be wired to the terminal on the PCB, and the 24V outputs will go to 2 XT30U connectors (not on the PCB). The case will expose the connectors and pogo pins, so new components can be added onto it.

A rough BOM:

• LCP300-24D5 PSU
• RPi Zero 2W
• Wemos D1 Mini
• 2x XT30U connectors
• 5mm pitch 2-pin screw terminal
• 2x 5-pin Magnetic Pogo Pin connectors
• IEC 320 C14 Power Socket

Completed the initial schematic for the base. I’m not completely sure this will even work as is. I have AC power from any wall outlet going into the PSU (likely a LCP300-24D5), and I use the 5V output to power the RPi and ESP board. I plan on using an I2C bus to communicate between the modules and the RPi, and UARC to communicate between the ESP and RPi, which I think I wired correctly? Then I have the 24V outputs from the PSU that I need to use, which will eventually be powering the motors. I need to add a switch between the PSU and receptacle so that you can turn the printer off and some XT30U connectors so the modules can get 24V power.
