# Board - Naze32 The Naze32 target supports all Naze hardware revisions. Revison 4 and Revision 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 | | | 3 | SoftSerial 1 | RC5 / PA6 | RC6 / PA7 | | | 4 | SoftSerial 2 | RC7 / PB0 | RC8 / PB1 | | * You cannot use USART1/TX/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 Input connector has the following pinouts when used in RX_PPM/RX_SERIAL mode | Pin | Identifier | Function | Notes | | --- | ---------- | -------------- | -------------------------------- | | 1 | N/A | Ground | | | 2 | Circle | +5V | | | 3 | 1 | PPM Input | 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 | Uart 2 TX | | | 6 | 3 | Uart 2 RX | | | 7 | 5 | Softserial1 TX | Enable `feature SOFTSERIAL` | | | | Led Strip | Enable `feature LED_STRIP`. | | 8 | 6 | Softserial1 RX | Enable `feature SOFTSERIAL` | | 9 | 7 | Softserial2 TX | Enable `feature SOFTSERIAL` | | 10 | 8 | Softserial2 RX | Enable `feature SOFTSERIAL` | | | | Current | Enable `feature CURRENT_METER`. Connect to the output of a current sensor, 0v-3.3v input |
