• Motion Sensors: combined set of MPU6000 (SPI1) and ICM42605/42688p (SPI4) for reliable orientation and motion detection.
• Barometer: Infineon DPS310 (I2C2) for accurate altitude measurement.
• OSD: AT7456E (SPI2) with the ability to connect via any UART for DJI FPV OSD.
• Blackbox: MicroSD card slot (SDIO) for recording telemetry and flight logs.
• Communications: 7 UART ports (1,2,3,4,6,7,8) with built-in inversion, 2 I2C ports, 1 CAN port, and SPI breakout for expansion.
• Outputs: 13 PWM outputs (including LED pad) for connecting ESCs and peripherals.
• Indicators: 3 LEDs for FC status (blue, red) and 3.3V BEC indicator (red).
• Analog-to-Digital Inputs: 6 ADC — VBAT, Current, RSSI, Analog AirSpeed, VB2, CU2.
• Connectors: JST-SH 1.0 8-pin for Vbat / G / Curr / Rx8 / S1 / S2 / S3 / S4; JST-GH 1.25 4-pin for 5V / CAN-H / CAN-L / G.
• Support for two cameras with switchable inputs and a physical ON/OFF switch for 5V/Vbat power with filter.
• Input Voltage: 6–36V (supports up to 8S LiPo).
• BEC: 5V 2A (max. 3A); LDO: 3.3V/max. 200mA.
• ADC Vbat2 supports up to 69V (voltage divider 1K:20K).
• Static Power: approximately 200mA at 5V with Betaflight and 150mA at 5V with ArduPilot.
• Supported Firmware: ArduPilot (MATEKH743, ChibiOS), BetaFlight (MATEKH743), INAV (MATEKH743, supported from version 3.0.1).
