5. WiFi Receiver Firmware

Firmware of WiFi receiver is operated as below. If smartphone push “Speed Up” button, Wi-Fi receiver will increase motor speed and it push “Speed Down” button, Wi-Fi receiver will decrease motor speed by 5 percentage.

skate-8

In the abnormal situation such as WiFi disconnection, the Wi-Fi receiver will stop motor. (even if motor stops, the skateboard will keep moving due to its acceleration.
