# 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](https://github.com/cleanflight/cleanflight/issues).

## 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.

| 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 | unused | |
|
|
| 10 | 8 | 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.
