3 The Naze32 target supports all Naze hardware revisions. Revison 4 and Revision 5 are used and
4 frequently flown by the primary maintainer. Previous Naze hardware revisions may have issues,
5 if found please report via the [github issue tracker](https://github.com/cleanflight/cleanflight/issues).
9 | Value | Identifier | RX | TX | Notes |
10 | ----- | ------------ | --------- | ------------------ | ------------------------------------------------------------------------------------------- |
11 | 1 | USART1 | RX / PA10 | TX / PA9 / TELEM | TELEM output is always inverted (for FrSky). Internally connected to USB port via CP2102 IC |
12 | 2 | USART2 | RC4 / PA3 | RC3 / PA2 | |
13 | 3 | SoftSerial 1 | RC5 / PA6 | RC6 / PA7 | |
14 | 4 | SoftSerial 2 | RC7 / PB0 | RC8 / PB1 | |
16 * You cannot use USART1/TX/TX/TELEM pins at the same time.
17 * You may encounter flashing problems if you have something connected to the RX/TX pins. Try disconnecting RX/TX.
