DC consume01 Release status: beta [box doku]

Description	12V power meter and distribution box
Author(s)	Severin
Last Version	0.1

A 12V power meter and distribution unit.

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

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...

We want to transmit voltage/current/power usage via LoRaWAN. The power meter can output that data via its TTL USB port.

First test with a ProMini LoRaWAN node and a level shifter

Custom PCB

I've build a custom board to connect an Arduino to the GC90 and transmit the output via LoRaWAN.
