I buy cheap GPS tracker for my electric Bike. This TK205 support up to 90V, as my bike using 48V so it compatible.
The free web tracker is only 1 year from the first data received by the server.
I install Traccar.org on my server. So my data will not going to unknown server.
The port for this GPS to traccar is 5023
This TK205 GPS tracker only support 2G network. The GPS is bad for receiving GPS in cloudy weather. And have bad 2G receiver.
