I made a little electronics bench from wood off cuts with an old PC power supply mounted underneath. I used the magnet slots in gridfinity baseplates as screw holes and made temporary mounts for the electronics in my drawer.

Complete: ESP32 Terminal Adapter (for 38-pin ESP32-Wroom Dev board) Raspberry Pi 3 B+ (other Pis should work if the mounting holes are the same) ESP32-Wrover 26-pin Dev Board (might fit 30 & 38 pin Dev Boards, but this only has two mounting holes - please comment if you've tried it) ESP8266-Wemos D1 R2 / Arduino Uno 8ch Relay board Banana Plug mount (2x1 Gridfinity - NOT TESTED)

Maybe Someday: ESP32-Wroom 38-pin Dev Board (4 mounting holes) ESP32 D1 Mini 4ch Relay board 2ch Relay board Something generic that doesn't rely on mounting holes (Ideas welcome)
