WideWheel PCB circuit board
Easy to install inside the top case (with main button) of your WideWheel.
Note that Mercane changed the connectors from PCB to throttle inside the top case. If your WideWheel was made as of April 2019, this is the right PCB for you.
If your WideWheel was made before, request an "old PCB" via email@example.com.
If you are unsure, open the top case and check if the throttle plugs directly onto the board (pre April 2019) or if the throttle connects to the board via a separate connector along the cable line (as of April 2019).
