The STM32H743VIT6 is STMicroelectronics' flagship Cortex-M7 MCU, running at an impressive 480 MHz with double-precision FPU and an extensive 1MB of SRAM across multiple bus matrices. The 2MB dual-bank Flash enables live firmware updates while the device is running — critical for mission-critical UAV autopilot deployments.
Used in professional-grade autopilot hardware including Holybro Durandal, mRo Control Zero, and industrial platforms running PX4 or ArduPilot. The H743 handles simultaneous processing of IMU data, GPS fusion, CAN-FD bus management, and high-resolution video/telemetry streams.
