RaccoonLab FMUv6X Autopilot

WARNING

PX4 does not manufacture this (or any) autopilot. Contact the manufacturer for hardware support or compliance issues.

The RaccoonLab FMUv6X flight controller is based on the following Pixhawk​® standards: Pixhawk Autopilot FMUv6X Standard, Autopilot Bus Standard, and Connector Standard.

Equipped with a high-performance H7 Processor, modular design, triple redundancy, temperature-controlled IMU board, and isolated sensor domains, it delivers exceptional performance, reliability, and flexibility. At RaccoonLab, we focus on DroneCAN and Cyphal-based onboard control system buses. Our autopilot is part of a larger DroneCAN and Cyphal ecosystem, making it an ideal choice for next-generation intelligent vehicles.

RaccoonLab offers versatile HATs for both Raspberry Pi and NVIDIA Jetson Xavier NX, enhancing connectivity and functionality. The Jetson Xavier NX HAT is designed to integrate the CAN bus with the Jetson Xavier NX, enabling access to Cyphal and DroneCAN protocols. The Raspberry Pi CM4 HAT provides robust features, including CAN bus connectivity, an LTE modem, internal voltage measurement, SWD debugging for other MCUs, and UART communication with PX4 over MAVLINK. These HATs expand the capabilities of devices, making them ideal for advanced robotics and UAV applications.

TIP

This autopilot is supported by the PX4 maintenance and test teams.

Key Design Points

额定电压

RaccoonLab FMUv6X can be triple-redundant on the power supply if three power sources are supplied. The three power rails are: POWER1, POWER2 and USB. The POWER1 & POWER2 ports on the RaccoonLab FMUv6X uses the 6 circuit 2.00mm Pitch CLIK-Mate Wire-to-Board PCB Receptacle.

Normal Operation Maximum Ratings

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

1. POWER1 and POWER2 inputs (4.9V to 5.5V)
2. USB input (4.75V to 5.25V)
