SwitchMaster is an Australian-designed 12V switching and control system with five individually fused 20A outputs.
Control lights, fridges, pumps, fans and other 12V accessories through the SwitchMaster app for Apple and Android devices. SwitchMaster can also be controlled from Apple Watch and compatible Garmin watches, the switches built into the unit, or existing automotive and marine 12V switches using the external switching inputs.
Integrated voltage, current and temperature monitoring allows outputs to be controlled automatically based on conditions you configure. Outputs can be grouped, switched based on voltage or temperature, and configured with individual low-voltage cut-outs.
SwitchMaster arrives pre-fused and ready to install and is compatible with 12V charging systems and battery chemistries.
SwitchMaster is now fully open source.
The PCB designs, schematics, firmware, mobile app source code, enclosure files and supporting documentation are available to download. The platform can be repaired, modified, manufactured or integrated into other systems.
The hardware uses readily available components and does not rely on proprietary electronics. Independent switching circuitry allows direct control of the outputs in the event of a microcontroller failure.
There are no subscriptions, cloud dependencies or vendor lock-in.
