+The dongle contains a micro controller and nRF24L01 transceiver, the circuit is similar to [http://download.ourdev.cn/bbs_upload482478/files_14/ourdev_435383.jpg this]. The switch is used to trigger a re-bonding, although the link is not active to start with. The LED flashes initially to indicate 'not bonded' and then goes out when the link is established, it flashes briefly as data is received from the wheel.
The wheel hardware contains the nRF24L01, a ATMEGA micro, and a PWM/Full-bridge driver (for controlling the motor). The micro scans the buttons mounted on the wheel, digitised the wheel/acc/brake positions and sends them to the PC/Dongle.
