Maybe some additional information might help:
Maybe serial debug via Rx/Tx pins that the manufacturer conveniently added to the PCB, might yield some information about the device.

Many cheap electronic device in Vietnam was imported from China. So I suppose it was an OEM model with different name. The output from UART is not helpful because it does not show anything useful about the device.
Hi, I want to use this with traccar but don't know what exactly its model. I bought it from local brand in my country, it also store data on seller' server and access through web or app, it seem like this tracker come from China. Does anyone know what is the model of this, any help will be appreciated.
