Description

The HCR-504B Flight Controller is engineered for demanding UAV applications requiring computational power and sensor redundancy. Its core is the STM32H7 series processor, paired with 1MB of RAM and 2MB of flash memory, providing ample resources for complex navigation algorithms and data logging via the onboard SD card slot. The unified JST-GH and USB-C connector system simplifies wiring while offering exceptional flexibility for peripheral expansion.

Built for stability in harsh environments, the controller features digital power connectors with extremely low ripple noise, ensuring clean power delivery to sensitive avionics. The extensive port selection, including multiple SPI, I2C, and GPIO options, allows seamless integration with a wide array of sensors, telemetry radios, and payloads, making it suitable for custom research, commercial, and heavy-lift drone builds.

Key Features

  • Redundant Sensor Architecture: Dual 3-axis accelerometers, gyroscopes, magnetometers, and barometers provide fault-tolerant attitude and heading reference for critical missions.
  • High-Speed Connectivity: Dual FD-CAN ports support modern drone peripherals like GPS modules and CAN ESCs at 8 Mbit/s data rates.
  • Expansion Ready: Five SPI ports and four I2C buses enable connection of multiple external sensors, vision systems, or companion computers.
  • Robust Power Design: Digital power monitoring on CAN lines and low-noise regulators ensure stable voltage for all connected components.
  • Professional Form Factor: Unified connector layout and optional Ethernet capability via carrier boards support scalable and clean system integration.
  • Extended Environmental Tolerance: Operates reliably across an industrial temperature range from -40°C to 80°C.

Applications

  • Advanced fixed-wing and VTOL (Vertical Take-Off and Landing) UAVs requiring redundant navigation for BVLOS (Beyond Visual Line of Sight) operations.
  • Heavy-lift and logistics drones where reliable flight control and extensive payload sensor integration are critical.
  • Custom research and development platforms for aerial mapping, surveying, and data collection needing high-speed processor and logging capabilities.
  • Commercial inspection and monitoring drones that operate in variable environmental conditions, benefiting from the wide operating temperature range.
  • Modular UAV systems designed for scalability, leveraging the controller's extensive FD-CAN, SPI, and I2C bus support.

Frequently Asked Questions

What is the primary advantage of the dual IMU system in the HCR-504B?

The dual redundant IMU system provides sensor-level fault tolerance. If one IMU fails or provides erroneous data, the flight controller can seamlessly switch to the backup, significantly increasing system reliability for critical commercial or autonomous drone operations.

What types of drones is this flight controller suitable for?

The HCR-504B is designed for advanced UAV platforms, including fixed-wing, multirotors, VTOLs, and heavy-lift drones. Its extensive I/O, processing power, and redundancy make it ideal for professional, commercial, and research applications where reliability and sensor integration are paramount.

How do I connect peripherals using the FD-CAN ports?

The dual FD-CAN ports support the CAN-FD protocol at 8 Mbit/s. You can directly connect compatible CAN peripherals like GPS modules, CAN-enabled ESCs, or other flight controllers using standard 2-wire CAN bus cabling, which simplifies wiring and improves noise immunity compared to traditional PWM or serial connections.

Does this controller support telemetry and ground station software?

Yes, when running ArduPilot or PX4 firmware, the HCR-504B fully supports standard telemetry protocols (MAVLink) over its serial ports. You can connect a telemetry radio to any serial port to establish a real-time data link with ground control software like Mission Planner or QGroundControl.
