CUAV Pixhawk V6X V2 Flight Controller

The CUAV Pixhawk V6X V2 is an FMU v6X-standard autopilot for PX4 and ArduPilot, aimed at mapping, survey, VTOL and industrial aircraft that need sensor redundancy and a wired link to a companion computer. It pairs an STM32H753 main processor with an STM32F103 I/O co-processor, triple IMUs, dual barometers and a 100 Mbps Ethernet port.

Key features

• Triple IMUs: IIM-42652, BMI088 and ICM-42686 on independent buses and power supplies, factory thermal-compensated, with automatic fault switching.

• Dual barometers and compass: ICP-20100 and BMP581 barometers plus an RM3100 magnetometer.

• 16 PWM outputs: M1–M8 from the I/O processor and A1–A8 from the FMU, with DShot and bidirectional DShot on A1–A8.

• 100 Mbps Ethernet: high-speed link to onboard computers and payloads.

• Extensive I/O: two CAN buses for DroneCAN devices, two power inputs, two GPS ports, three TELEM ports, UART4 and a TF card slot.

Specifications

• Main processor: STM32H753IIK6, 480 MHz

• I/O co-processor: STM32F103 (Cortex-M3)

• IMUs: IIM-42652, BMI088, ICM-42686

• Barometers: ICP-20100, BMP581

• Magnetometer: RM3100

• PWM outputs: 16

• Ports: 2x POWER, 2x CAN, 2x GPS, 3x TELEM, UART4, Ethernet, PPM RC, SBUS/DSM/RSSI in, SBUS out, 2x USB, TF card slot

• Power input: 4.85–5.45 V on POWER ports; 12–70 V battery through a CAN PMU 2 Lite power module

• Servo rail input: 0–9.9 V

• Operating temperature: -20 to 85 °C

• Weight: 97.9 g (core module 43.1 g, carrier board 54.8 g)

The V2 core fits carrier boards made for the first-generation V6X, but firmware is not interchangeable: PX4 needs v1.17 or later, and your ArduPilot build must list V6X v2 support, as firmware for the first-generation V6X will not run on it.
