## Serial Port Mapping

| UART   | Device     | Port                       |
| ------ | ---------- | -------------------------- |
| USART1 | /dev/ttyS0 | IO Processor Debug         |
| USART2 | /dev/ttyS1 | TELEM1 (flow control)      |
| USART3 | /dev/ttyS2 | TELEM2 (Raspberry pi cm3+) |
| UART4  | /dev/ttyS3 | GPS1                       |
| USART6 | /dev/ttyS4 | PX4IO                      |
| UART7  | /dev/ttys5 | Debug console              |
| UART8  | /dev/ttyS6 | TELEM4                     |

## Voltage Ratings

**ThePeach FCC-R1** can be double-redundant on the power supply if two power sources are supplied. The two power rails are: **POWER** and **USB**.

Note:

1. The output power rails **FMU PWM OUT** and **I/O PWM OUT** do not power the flight controller board (and are not powered by it). You must supply power to one of **POWER** or **USB** or the board will be unpowered.
2. The USB do not power the **Raspberry Pi CM3+**. You must supply power to **POWER** or the Raspberry Pi CM3+ will be unpowered.

**Normal Operation Maximum Ratings**

Under these conditions, all power sources will be used in this order to power the system:

1. POWER input (5V to 5.5V)
2. USB input (4.75V to 5.25V)

**Absolute Maximum Ratings**

Under these conditions, all power sources cause permanent damage to the flight controller.

1. POWER input (5.5V Over)
2. USB input (5.5V Over)
