SEQURE H743 V2 & E70 G2 Stack AM32 - flight controller + ESC controller 4-8S 70A

Description

SEQURE H743 V2 & E70 G2 Stack FC is an advanced flight controller and 4-in-1 ESC stack designed for demanding FPV racing and freestyle drones. The system combines a high-performance flight controller based on the STM32H743 with the powerful E70 G2 ESC, ensuring extremely fast response times and stable motor control. Thanks to the modern ICM42688P gyroscope, the system provides highly precise motion tracking and stable flight performance even during aggressive maneuvers. An integrated barometer and OSD chip enable extended real-time flight data monitoring.

The flight controller features 16 MB Black Box memory for detailed flight log analysis and offers 6 UART ports, providing excellent flexibility for connecting peripherals such as GPS modules, receivers, or video systems. Integrated BEC outputs provide stable 5V and 10V power rails, allowing direct support for systems such as DJI O3/O4. The system supports 4–8S LiPo/LiHV input voltage, making it suitable for a wide range of builds from lightweight to high-power setups.

The E70 G2 4-in-1 ESC is based on the STM32G071 processor and runs AM32 firmware, providing smooth and precise motor control. It supports PWM frequencies from 16 kHz to 128 kHz, resulting in quieter and more responsive motor operation. The ESC delivers a continuous current of 70 A per channel and a peak current of 150 A, making it suitable for demanding racing configurations. Telemetry support allows real-time monitoring of speed, temperature, and current draw. A multilayer PCB with increased copper thickness improves cooling and durability under load. Angled solder pads simplify installation and improve wiring layout. The stack is designed in a 30.5×30.5 mm mounting standard for broad compatibility with FPV frames.
