In all FOC control modes, the controller features maximum motor speed and maximum motor current protection. This brings great advantages to fulfil the needs of many robotic applications while maintaining safe operation.

## Dual Inputs
The firmware supports the input to be provided from two different sources connected to the Left and Right cable, respectively. To enable dual-inputs functionality uncomment `#define DUAL_INPUTS` in config.h for the respective variant. Various dual-inputs combinations can be realized as illustrated in the following table:
| Left | Right | Availability |
| --- | --- | --- |
| ADC<sup>(0)</sup> | UART<sup>(1)</sup> | VARIANT_ADC |
| ADC<sup>(0)</sup> | {PPM,PWM,iBUS}<sup>(1)</sup> | VARIANT_{PPM,PWM,IBUS} |
| ADC<sup>(0)</sup> | Sideboard<sup></sup><sup>(1*)</sup> | VARIANT_HOVERCAR |
| UART<sup>(0)</sup> | Sideboard<sup>(1*)</sup> | VARIANT_UART |
| UART<sup>(1)</sup> | Nunchuk<sup>(0)</sup> | VARIANT_NUNCHUK |
<sup>(0)</sup> Primary input: this input is used when the Auxilliary input is not available or not connected.<br/>
<sup>(1)</sup> Auxilliary input: this inputs is used when connected or enabled by a switch<sup>(*)</sup>. If the Auxilliary input is disconnected, the firmware will automatically switch to the Primary input. Timeout is reported **only** on the Primary input.
With slight modifications in config.h, other dual-inputs combinations can be realized as:
| Left | Right | Possibility |
| --- | --- | --- |
| Sideboard<sup>(1*)</sup> | UART<sup>(0)</sup> | VARIANT_UART |
| UART<sup>(0)</sup> | {PPM,PWM,iBUS}<sup>(1)</sup> | VARIANT_{PPM,PWM,IBUS} |
