Hardware Platform and Sensors: The module is equipped with a powerful STM32H757 processor, ensuring high-speed processing of navigation data and increased operational reliability. Built-in sensors include an industrial-grade RM3100 compass, two new ICM42688 MEMS accelerometer chips, a gyroscope, and a barometer. The main navigation processor runs on the ChibiOS real-time operating system, making the architecture open and convenient for developers with specific navigation system requirements.
Purpose and Compatibility: Here3+ is built on the CAN protocol and is not compatible with classic interfaces without an appropriate adapter; however, it is possible to switch to I2C using an internal switch. The module is protected from dust and splashes and has an improved design for field use. It supports future firmware updates, integration with ground control stations, and operation with mission planners.
