The original case for the Brickmaster control system. Brickmaster is a low-voltage switching system that uses MQTT, designed for integration with Home Assistant. Originally designed for controlling legos, hence the name!
My default build provides eight 5v and eight 9v outputs, and takes a 9v input. I use modular port blocks so ports can be rearranged without having to reprint the whole thing. 9v and 5v connectors are different, to prevent improper connections. Connectors friction fit very snugly into the modules.
Software
Available in this repo.
It's relatively reliable but can have glitches, so don't expect it to be rock-solid-production ready. Definitely DO NOT use for anything safety related.
