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

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
