SEQURE Blueson A2 30*30 2-8S 70A ESC with AM32 Firmware

SEQURE Blueson A2 AM32 ESC 30×30 2–8S 70A

The SEQURE Blueson A2 4-in-1 ESC is a high-performance choice for FPV pilots and RC hobbyists looking for reliable power delivery, smooth throttle response, and broad battery compatibility. Built around a fast 32-bit processor and running AM32 firmware, this ESC is designed to keep up with demanding builds, from powerful freestyle setups to larger heavy-lift platforms.

Its high-quality PCB with a thick copper layer improves current handling and heat dissipation, while premium MOSFETs help boost efficiency and overall flight performance. The result is cleaner power, responsive motor control, and a more confident flying experience.

With support for a dynamic PWM frequency range from 8 kHz to 128 kHz, the Blueson A2 delivers precise speed control and smoother throttle feel. It also supports 2–8S LiPo input, giving you the flexibility to use it across a wide range of aircraft configurations.

The 30.5 × 30.5 mm mounting pattern makes it a great fit for larger frames and higher-payload builds. Enlarged angled solder pads help keep motor wires neatly arranged and make soldering easier during installation.
