 ## Example Variants
 
 - **[VARIANT_ADC](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Variant-ADC)**: The motors are controlled by two potentiometers connected to the Left sensor cable (long wired)
-- **[VARIANT_USART](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Variant-USART)**: The motors are controlled via serial protocol (e.g. on USART3 right sensor cable, the short wired cable). The commands can be sent from an Arduino. Check out the [hoverserial.ino](/Arduino/hoverserial) as an example sketch.

 - **[VARIANT_NUNCHUK](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Variant-Nunchuk)**: Wii Nunchuk offers one hand control for throttle, braking and steering. This was one of the first input device used for electric armchairs or bottle crates.
 - **[VARIANT_PPM](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Variant-PPM)**: RC remote control with PPM Sum signal.
 - **[VARIANT_PWM](https://github.com/EFeru/hoverboard-firmware-hack-FOC/wiki/Variant-PWM)**: RC remote control with PWM signal.
