ARK Electronics ARKV6X
WARNING
PX4 does not manufacture this (or any) autopilot. Contact the manufacturer for hardware support or compliance issues.
The USA-built ARKV6X flight controller is based on the FMUV6X and Pixhawk Autopilot Bus open source standards.
With triple synced IMUs, data averaging, voting, and filtering is possible. The Pixhawk Autopilot Bus (PAB) form factor enables the ARKV6X to be used on any PAB-compatible carrier board, such as the ARK Pixhawk Autopilot Bus Carrier.

INFO
This flight controller is manufacturer supported.

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 ARKV6X bootloader enables only UART7 (TELEM1), so when flashing firmware over UART with px4_uploader.py you must connect to the TELEM1 port — no other UART will respond in bootloader mode.
