Board – Naze32

The Naze32 target supports all Naze hardware revisions. Revision 4 and 5 are used and
frequently flown by the primary maintainer. Previous Naze hardware revisions may have issues,
if found please report via the github issue tracker.

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
