Qio-Tek Zealot H743 Flight Controller


Zealot H743 flight controller based on the STM32H743VIT6 processor. 2 MB flash and 1MB ram with 3x accelerometers, 2x barometers, a built in compass, 2x internal BECs to power the servo rail and IO ports separately from the main power. 14 x PWM outputs, 2x CAN port, 2x i2c ports, 2x GPS inputs and up to 5x UARTS. Built in/integrated analogue OSD. External safety switch/buzzer included. This advanced FC is fully compatible with Ardupilot 4.2.2 and above.

SKU: ZH743 Categories: ,


The QioTek ZealotH743 is an internal vibration dampened autopilot with a protective CNC metal case for ruggedness. It features fully redundant sensors, an expanded number of outputs, temperature-controlled IMUs, and has an integrated AT7456E OSD chip. Available in 3 editions Standard, Industrial and Industry Application, you can select packages with and without GPS. Check the specs carefully - the Zealot-H743 has higher specs than many competors.!
