SEQURE Blueson A2 AM32 65A 4-in-1 ESC for 2-6S FPV Drones | 30.5mm Mount

Meet the SEQURE Blueson A2 AM32 65A 4-in-1 ESC, a compact control unit designed for high-performance FPV racing and freestyle drones. Built around a robust 32-bit AT32F421 processor and a thick copper PCB, it emphasizes smooth throttle response and reliable current handling in demanding flight conditions.

Core specs at a glance: continuous current 65A, peak 120A, voltage range 2-6S LiPo/LiHV, and support for digital protocols including DShot600/300/150, Oneshot, Multishot, and PWM. Telemetry return is supported, and there is no BEC onboard.

In practice, you’ll notice the effect of a high-quality MOSFET stage and optimized heat management. The design emphasizes efficient heat dissipation and minimal power loss, which can help maintain performance during long sessions or aggressive freestyle with quick throttle changes.

What’s included and how it’s built for install

• 4-in-1 ESC module with universal 30.5x30.5 mm mounting, aligned for larger drones and load-type builds.
• Angled extended solder pads and multi-layer PCB to simplify wiring and improve current handling.

The package also includes the required cables and a solid capacitor to support stable power delivery to your flight controller and motors. Expect a neat, streamlined install with fewer soldering obstacles thanks to the thoughtful pad layout.

Real-world use cases and benefits

• Racers can benefit from precise throttle response and stable power during high-speed runs.
• Freestyle pilots may enjoy smoother throttle control during flips and rapid transitions.
• Pilots running 2S to 6S packs can pair this ESC with a variety of motors and airframes for different flight profiles.

Compatibility and care notes

Designed with 30.5 mm mounting in mind and with an emphasis on heat management, this ESC supports large-sized flight vehicles while keeping installation tidy. Telemetry support adds data feedback, though no BEC output is provided, so plan your power distribution accordingly.
