See the depot-oben-eda folder for kicad Drawings Open the project file with KiCad (used version is 8) to view the schematic and board design for the small transistor board for opening the solenoid.
The pinout for the Raspberry Pi is as follows (BCM numbering!):
Pull up SWITCH to turn on the solenoid, don't hold too long because it tends to overheat quite fast. (<= 500 ms)
CHECK is high-z when the locker is open and GND when it is closed. To prevent floating state
pull up the GPIO pin to which CHECK is connected.
| Board Pin | RaspberryPi Pin |
|---|---|
| SWITCH | GPIO21 |
| CHECK | GPIO20 |
| GND | GND |
For pinout info see pinout.xyz/
Software
See the Software Docs for details.
Deployment
There is seperate guide for how to deploy the software from scratch.

Questions
How big is the Depot oben eda PCB?
It measures 45 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Depot oben eda use?
12 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Depot oben eda KiCad files?
From the jdav-freiburg/locker repository on GitHub, at the commit this page was made from: the board is depot-oben-eda/depot-oben-eda.kicad_pcb and its schematic depot-oben-eda/depot-oben-eda.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Depot oben eda design in my own project?
Its repository publishes it under the BSD-3-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
