Serial Ports

Value Identifier RX TX Notes
1 USART1 RX / PA10 TX / PA9 / TELEM TELEM output is always inverted (for FrSky). Internally connected to USB port via CP2102 IC
2 USART2 RC4 / PA3 RC3 / PA2
4 SOFTSERIAL1 RC5 / PA6 RC6 / PA7
5 SOFTSERIAL2 RC7 / PB0 RC8 / PB1
  • You cannot use USART1/TX/TELEM pins at the same time.
  • You may encounter flashing problems if you have something connected to the RX/TX pins. Try disconnecting RX/TX.

Pinouts

The 10 pin RC I/O connector has the following pinouts when used in RX_PPM/RX_SERIAL mode.

Pin Identifier Function Notes
1 Ground
2 Circle +5V
3 1 RX_PPM Enable feature RX_PPM
4 2 RSSI_ADC Enable feature RSSI_ADC. Connect to the output of a PWM-RSSI conditioner, 0v-3.3v input
5 3 USART2 TX
6 4 USART2 RX
7 5 LED_STRIP Enable feature LED_STRIP
8 6 unused
9 7 Sonar Trigger
10 8 Sonar Echo / CURRENT Enable feature CURRENT_METER Connect to the output of a current sensor, 0v-3.3v input

When SOFTSERIAL is enabled, LED_STRIP and CURRENT_METER are unavailable, but two SoftSerial ports are made available to use instead.

Pin Identifier Function Notes
7 5 SOFTSERIAL1 RX Enable feature SOFTSERIAL
8 6 SOFTSERIAL1 TX
9 7 SOFTSERIAL2 RX
10 8 SOFTSERIAL2 TX
