After soldering, with components:
Firmware development:
The PCB was created with LibrePCB. PCB art was made using svg2librepcb (with some manual adjustments).
Firmware is being developed in Rust. The microcontroller is an STM32F411.
The whole project is still WIP, you can check it out here: GitHub - dbrgn/chicken-coop: Hardware and firmware for our chicken door automation I already discovered that I’ll need a second revision, because I forgot about the ground pin for the motor controller
