Author(s)  Severin
Last Version  0.1

A 12V power meter and distribution unit.

  • Input: 12V via speakon connector
  • Output: 12V via 3 car "lighter" sockets
  • Power metering: GC90 power meter

Power meter

The GC90 power meter can deal with up to 100V DC at 20A. It also has a TTL port via USB connector.


  • Connect LoRaWAN Arduino to power meter and transmit voltage/current/power usage
  • Add fuses
    • These resettable fuses can deal with up to 48V (depending on the rating, some only with lower voltages): Reichelt
    • Bigger DC fuses are available here at solarbag (probably not for this part of the setup though)
  • Option for 48V -> 12V converter
  • additional connectors, like USB, USB-C, passive PoE...
