Features Cost-efficient high precision and RTK supported GNSS chip (base station needed for RTK). Positioning accuracy down to centimetre-level in an ideal environment. Brand new design with improved visibility on signal LEDs. Better dust and water resistance (Not guaranteed to be water-proof under any situation due to the complexity of the operating environment). The high data rate, upgradeability, noise immunity, and real-time features benefited from CAN protocol Equipped with STM32F302 high-performance processor in a real-time operating system. The framework developed by Hex provides additional stabilities. Supports future firmware updates. Support from ground control software. Future updates will be available from Mission Planner. Built-in a complete set of Inertial Measurement Unit (compass, gyroscope, and accelerometer), which satisfy advanced navigation needs. Specification Receiver Type u-blox M8 high precision GNSS modules (M8P) Satellite Constellation GPS L1C/A, GLONASS L1OF, BeiDou B1I Positioning accuracy 3D FIX: 2.5 m / RTK: 0.025 m Processor STM32F302 IMU sensor ICM20948 Navigation Update Rate Max: 8Hz Communication Protocol CAN Operating Temperature -40℃ to 85℃ Dimension 68mm x 68mm x 16mm Weight 48.8g Pinout Pin Definition Cable Colour 1 VCC_5V Red 2 CAN_H White 3 CAN_L Yellow 4 GND Black Configuration 1. Using Ardupilot Firmware： Using one Here3： Connect the 4pin CAN cable connector to CAN1 or CAN2 port on the flight controller. power the flight controller and connect it to Mission Planner. Go to “Config/Tuning > Full Parameter List” and modify the following parameters: CAN_D1_PROTOCOL: 1 CAN_D2_PROTOCOL: 1 CAN_P1_DRIVER: 1 CAN_P2_DRIVER: 1 GPS_TYPE: 9 NTF_LED_TYPES: 231 Click “Write Params” when done. CAN functions will be available after rebooting the flight controller. Using two Here3： You need the latest Ardupilot firmware to manually assign different node ids to Here3 to work properly (node ids are 0-125). Connect each Here3 4Pin CAN cable to the CAN1 port of the flight controller(one at a time), and conduct the following procedure. Select “install firmware” from Mission Planner and load the latest copter and plane firmware. No refund Policy for this Product
