NineNot GT Speedlimiter without remote

This is the NineNot GT Speed limiter without RF remote.
This product will limit your GT1, GT1D or GT2 to the defined speed regulation (22 or 25 Km/h) when the scooter starts.
(Note: For GT1D and GT1E you will need to unlock all speeds via ST-Link)
After that you can via Mobile phone set the speed higher (Wifi connection to chip).

A full guide but also info how to build on your own can be found at: https://rollerplausch.com/threads/tutorial-ninebot-gt-series-german-maneuver.10100/

Keep in mind this device requires an unlocked GT1 or GT2 with US / China serial and speedsliders in the original Ninebot app.
