While the search results did not reveal an official datasheet or press release, multiple sources point to the MH-FC V2.2 as a key product in M-HIVE's "STM32 Drone programming from scratch" course.
Creating drones that can pick up and move items over terrain difficult for land-based robots.
Unlike standard commercial flight controllers that run pre-built open-source software, the MH-FC V2.2 is meant to be coded entirely from a blank slate using C programming and STM32CubeIDE. 🚀 Key Hardware Specifications
You are running a legacy V1.x system with highly customized, unmaintained drivers. In that case, plan a staged migration over 3–6 months. Also, if your hardware is non-compatible (check the HCL for V2.2-specific chip revisions), stay on V2.1.

No firmware is without quirks. The most common issue reported with Mh-fc V2.2 is "gyro overrun errors" when used with MPU6000 sensors over SPI at 32MHz. The solution is to drop the SPI speed to 16MHz using set gyro_spi_speed = 16000000 .
Includes fail-safe motor force stops, sensor connection checks, and PID gain load status monitoring.
The most common issue users face is the sensor being "always on" or not detecting anything. This is usually a calibration issue.

Increases the detection distance (higher sensitivity).
Even a robust release like Mh-fc V2.2 can present challenges. Here are the most frequently reported issues and their solutions.
Unlike commercial boards optimizing for space, the MH-FC V2.2 embeds to teach diverse sensor-handling methodologies:
While detailed, public-facing spec sheets for the MH-FC V2.2 are not widely published, its use and design are intrinsically linked to the course curriculum, which provides clear insight into its capabilities and the hardware it interacts with. The board is designed to work with the STM32CubeIDE, a free integrated development environment from STMicroelectronics, making professional-level development accessible.
