HOLYBRO CAN Hub
HOLYBRO CAN Hub – CAN Port Expansion with Integrated Power Supply The HOLYBRO CAN Hub is an active CAN expansion module for flight controllers and CAN-compatible peripheral devices. The module expands a single existing CAN connection to up to four CAN ports and additionally provides an independent power supply for connected devices. An integrated step-down voltage regulator allows the CAN Hub to be powered directly from a 2S to 12S battery. The input voltage is regulated to a stable 5.2 V and supplied through the four CAN outputs to connected sensors and other CAN peripherals. The CAN Hub is particularly suitable for UAVs, UGVs, VTOL platforms, and other unmanned systems where multiple CAN or DroneCAN components need to be connected to a flight controller. One CAN Port – Up to Four Connections The HOLYBRO CAN Hub expands one CAN connection of the flight controller to a total of four CAN outputs. This allows multiple compatible devices to be connected centrally to the CAN bus system. This is particularly useful in more complex system architectures where GNSS modules, magnetometers, airspeed sensors, LiDAR sensors, power modules, or other CAN-compatible components are used simultaneously. 1 × CAN input 4 × CAN outputs Central CAN bus distribution Suitable for multiple CAN peripheral devices Independent Power Supply Many flight controllers already provide a 5 V power supply through their CAN connections. However, the available voltage and current may be limited by additional connected components and the maximum load capacity of the flight controller's power supply. The HOLYBRO CAN Hub therefore features a separate power supply. The module can be powered directly from a 2S to 12S supply through the XT30 input. The integrated voltage regulator then provides a stable output voltage of 5.2 V ±0.15 V for the connected CAN devices. Up to 1 A per CAN Port Each of the four CAN outputs can supply up to 1 A at 5.2 V. The maximum combined current across all four CAN outputs is 3 A. Output Voltage: 5.2 V ±0.15 V Maximum Current per CAN Port: 1 A Maximum Total Current: 3 A Wide Input Voltage Range With an input voltage range of 2S to 12S, the CAN Hub can be integrated directly into a wide variety of power architectures. Power is supplied through a compact XT30 connector. Input Voltage: 2S–12S Power Input: XT30 Integrated step-down voltage regulator For CAN and DroneCAN Peripherals The CAN Hub is suitable for expanding flight controller systems that use multiple CAN-based components. These may include GNSS and RTK systems, external magnetometers, airspeed sensors, optical sensors, LiDAR modules, and other DroneCAN-compatible devices. Thanks to the separate power supply, connected devices do not have to rely exclusively on the flight controller's 5 V power supply. This can simplify the power architecture, particularly in systems with multiple CAN devices.

HOLYBRO DroneCAN RM3100 Professional Grade Compass
HOLYBRO RM3100 Professional DroneCAN Compass – Precision 3-Axis Magnetometer for Unmanned Systems The HOLYBRO RM3100 Professional DroneCAN Compass is a high-precision 3-axis magnetometer for UAVs, UGVs, robotics platforms, and other unmanned systems. The sensor is based on PNI magneto-inductive technology and is designed for applications requiring reliable magnetic orientation and high heading accuracy. With its high resolution, extremely low magnetic hysteresis, and excellent signal-to-noise ratio, the RM3100 enables precise magnetic field measurements. This makes the magnetometer particularly suitable for professional navigation and autopilot systems where reliable heading determination is required. Communication with the flight controller is handled digitally via DroneCAN. This allows the RM3100 to be easily integrated into existing CAN bus systems without occupying an additional serial port on the flight controller. The robust enclosure provides an IP66 protection rating, making the sensor suitable for operation in demanding environmental conditions. Precision 3-Axis Magnetometer The RM3100 measures the magnetic field along three axes and provides precise magnetic field data to the flight controller. This information can be used to determine the orientation and heading of a UAV or other unmanned vehicle. PNI's magneto-inductive sensor technology provides high repeatability and extremely low magnetic hysteresis. Depending on the selected cycle-count configuration, the magnetometer achieves a sensitivity of up to 13 nT. Reduction of Magnetic Interference Electric motors, high-current wiring, batteries, power distribution systems, and metallic components can influence the local magnetic field of an unmanned system and distort magnetometer measurements. Using an external magnetometer allows the sensor to be mounted farther away from these potential sources of interference. This can contribute to more reliable heading determination, particularly on high-performance UAVs and other electrically powered platforms. For the most accurate measurements, the RM3100 should therefore be installed in a position as far away as practical from motors, high-current wiring, and larger metallic components. DroneCAN Communication Communication between the RM3100 and the flight controller is handled through the robust DroneCAN protocol. CAN-based data transmission is particularly suitable for professional UAV and robotics platforms where multiple sensors and peripheral devices need to communicate reliably. Multiple DroneCAN-compatible devices can operate on a shared CAN bus, helping simplify wiring in more complex systems. At the same time, the magnetometer does not require an additional UART port on the flight controller. Digital communication via DroneCAN Robust CAN bus data transmission No additional UART port required Multiple DroneCAN devices can operate on a shared bus Suitable for longer cable runs within the system Software-controlled CAN termination PNI RM3100 Sensor Technology The RM3100 is based on PNI's proprietary magneto-inductive sensor technology. This technology enables precise magnetic field measurements with high resolution and repeatability. The measurement range is -800 to +800 µT.

Single-Axis Sample Rate 1600 Hz 850 Hz 440 Hz The specified maximum sampling rates apply to a single axis. For the maximum sampling rate in 3-axis operation, the respective value must be divided by three. IP66-Rated Enclosure The current RM3100 module is supplied in a robust enclosure with an IP66 protection rating. The enclosure provides complete protection against dust ingress as well as protection against powerful water jets. This makes the magnetometer suitable for UAVs, UGVs, and other unmanned systems operating outside controlled laboratory environments.
