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
