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(0) UART(1) VARIANT_ADC
ADC(0) {PPM,PWM,iBUS}(1) VARIANT_{PPM,PWM,IBUS}
ADC(0) Sideboard(1*) VARIANT_HOVERCAR
UART(0) Sideboard(1*) VARIANT_UART
UART(1) Nunchuk(0) VARIANT_NUNCHUK

(0) Primary input: this input is used when the Auxilliary input is not available or not connected.
(1) Auxilliary input: this inputs is used when connected or enabled by a switch(*). 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(1*) UART(0) VARIANT_UART
UART(0) {PPM,PWM,iBUS}(1) VARIANT_{PPM,PWM,IBUS}
{PPM,PWM,iBUS}(1) Nunchuk(0) VARIANT_{PPM,PWM,IBUS}
