MATEKSYS H7A3-SLIM Flight Controller - ICM42688P - 30x30

The MATEKSYS H7A3-SLIM Flight Controller offers high performance in a compact 30x30mm design. It features the STM32H7A3RIT6 MCU, 280MHz Cortex-M7 processor, 1.4MB RAM, and 2MB Flash. With the ICM42688P IMU, SPL06-001 barometer, AT7456E OSD, and 128MB Flash Blackbox, it provides precise data and ample logging. The controller includes 6 UARTs, 11 PWM outputs, 1 I2C, 1 CAN port, and 4 ADC channels. It also has three status LEDs, a USB Type-C port, and a switchable 9V output. With a 30.5 x 30.5mm mounting pattern, 4mm holes, 3mm grommets, and weighing just 7g, it’s perfect for FPV racing and freestyle flying. A 3D step file is included for custom integration.
