I have two of these damaged now and seek a circuit or advice on how the circuit might operate.
It has a shunt on the negative line and reads voltage and current from it. Other in and out records are kept and capacity calculated .
The radio part is a transmitter on the shunt component and a receiver separately powered or ,connected by a USB cable if wanted which supplies power also. It uses two nRF24L01 radio modules (they are working ). There is plenty available on these modules.
So I'm looking at the transmitter/shunt and trying to work out how it operates
Anyone got any clues?
Here is a sample with a lot of detail toohttps://www.aliexpress.com/item/DC-...0c89-4e98-895e-a06807106962&priceBeautifyAB=0
