Components Used

Every part in Tidevue is replaceable. We believe in right-to-repair and full transparency about what goes into your reef controller.

Our Philosophy

Right to Repair

Every component can be replaced by you. No proprietary parts, no artificial locks. Your hardware, your choice.

Standard Parts

We use industry-standard components available from multiple suppliers. You're never locked into a single source.

Open Hardware

Our custom carrier board is designed in-house with KiCad. Schematics and PCB layouts will be published.
