Manuals & Hardware Files
Every number, documented.
Hardware documentation, PCB files, schematics, and BOM - all open. The firmware running the inverter MCU is proprietary. We don't release it. That's our moat. The hardware is yours to study, modify, and build on.
The firmware that runs on the inverter MCU is proprietary. We don't publish it - not binaries, not source. It's our engineering moat. You're welcome to reverse-engineer it. Builders who go deep and share findings publicly in our Discord get hardware, pre-release units, and direct access to our engineering team.

Firmware changelog
We publish a public changelog for each firmware update - version number, what changed, and any safety-relevant notes. Binaries are not included. The changelog is the record. If something in a release affects how you interact with the hardware, you'll find it here.
