| --- | --------- | -------------------------------- |
| 1 | Ground | |
| 2 | +5V | |
| 3 | PPM Input | Enable `feature RX_PPM` |
| 3 | Unused | |
| 4 | SoftSerial1 TX / Sonar trigger | |
| 5 | SoftSerial1 RX / Sonar Echo | |
| 5 | SoftSerial1 RX / Sonar Echo / RSSI_ADC | Used either for SOFTSERIAL, SONAR or RSSI_ADC*. Only one feature can be enabled at any time. |
| 6 | Current | Enable `feature CURRENT_METER`. Connect to the output of a current sensor, 0v-3.3v input |
| 7 | Battery Voltage sensor | Enable `feature VBAT`. Connect to main battery using a voltage divider, 0v-3.3v input |
| 8 | RSSI | Enable `feature RSSI_ADC`. Connect to the output of a PWM-RSSI conditioner, 0v-3.3v input |
| 8 | PPM Input | Enable `feature RX_PPM` |
*Connect to the output of a PWM-RSSI conditioner, 0v-3.3v input.
The 6 pin RC_Output connector has the following pinouts when used in RX_PPM/RX_SERIAL mode
