Sequre Blueson A1 70A 8S AM32 ESC

Product description

The Sequre Blueson A1 70A 8S AM32 ESC was designed for FPV pilots looking for maximum power, high efficiency, and modern ESC technology in a compact package. With a continuous current rating of 70A, support for 2–8S LiPo batteries, and the powerful AM32 firmware, this ESC is perfect for demanding freestyle, racing, long-range, and high-power builds.

Inside, a powerful 32-bit AT32F421 processor enables fast signal processing and precise motor control. The modern AM32 firmware supports PWM frequencies from 8 to 96 kHz, resulting in exceptionally smooth response, higher efficiency, and more precise motor control.

Thanks to the integrated current sensor and ESC telemetry, key flight data is available at all times for flight controllers and OSD. The compact 20x20 mm mounting format makes the Blueson A1 particularly appealing for modern FPV builds where performance and weight must be optimally balanced.

With support for up to 8S LiPo systems, this ESC offers enormous power reserves for high-performance motors and high-voltage setups. This makes the Blueson A1 ideal for pilots who expect uncompromising performance and maximum reliability.
