# ARK Electronics ARKV6S
|
|
|
|
::: warning
|
|
PX4 does not manufacture this (or any) autopilot.
|
|
Contact the [manufacturer](https://arkelectron.com/contact-us/) for hardware support or compliance issues.
|
|
:::
|
|
|
|
The USA-built [ARKV6S](https://arkelectron.gitbook.io/ark-documentation/flight-controllers/arkv6s) flight controller is a low-cost, single-IMU variant of the [ARKV6X](../flight_controller/ark_v6x.md), based on the [FMUV6X and Pixhawk Autopilot Bus open source standards](https://github.com/pixhawk/Pixhawk-Standards).
|
|
|
|
The Pixhawk Autopilot Bus (PAB) form factor enables the ARKV6S to be used on any [PAB-compatible carrier board](../flight_controller/pixhawk_autopilot_bus.md), such as the [ARK Pixhawk Autopilot Bus Carrier](../flight_controller/ark_pab.md).
|
|
|
|
|
|
|
|
::: info
|
|
This flight controller is [manufacturer supported](../flight_controller/autopilot_manufacturer_supported.md).

## Serial Port Mapping
|
|
|
|
| UART | Device | Port |
|
|
| ------ | ---------- | ------------- |
|
|
| USART1 | /dev/ttyS0 | GPS |
|
|
| USART2 | /dev/ttyS1 | TELEM3 |
|
|
| USART3 | /dev/ttyS2 | Debug Console |
|
|
| UART4 | /dev/ttyS3 | UART4 & I2C |
|
|
| UART5 | /dev/ttyS4 | TELEM2 |
|
|
| USART6 | /dev/ttyS5 | PX4IO/RC |
|
|
| UART7 | /dev/ttyS6 | TELEM1 |
|
|
| UART8 | /dev/ttyS7 | GPS2 |
|
|
|
|
::: info
|
|
The mapping above applies to the running PX4 firmware.
|
|
The ARKV6S bootloader enables only `UART7` (TELEM1), so when flashing firmware over UART with [`px4_uploader.py`](https://github.com/PX4/PX4-Autopilot/blob/main/Tools/px4_uploader.py) you must connect to the `TELEM1` port — no other UART will respond in bootloader mode.

## Building Firmware

|
|
|
```sh
|
|
make ark_fmu-v6s_default
|
|
```
