Description
The SEQURE Blueson ESC A2 8S 70A is built for pilots who demand high performance, durability, and smooth control in every flight. Designed with a premium ultra-thick copper PCB, this ESC ensures exceptional current-carrying capability while reducing heat buildup. Combined with top-grade MOSFETs, it delivers superior efficiency, stability, and reliability even under the most extreme conditions.
At the heart of the Blueson A2 is a high-speed 32-bit AT32F421 processor, paired with AM32 firmware. This setup provides support for a fully dynamic PWM refresh rate from 8KHz to 128KHz, offering lightning-fast response and ultra-smooth throttle control. Whether you’re racing at top speed or fine-tuning your freestyle tricks, the Blueson A2 reacts instantly and precisely to your commands.
Flexibility is another standout feature. With support up to 8S LiPo/LiHV batteries, this ESC adapts to a wide range of builds and power needs. Its continuous current handling of 70A (8S), along with peak bursts of up to 150A (8S), ensures it can keep up with high-powered motors and aggressive flying styles.
Installation is simple thanks to the 30.5 × 30.5 mm mounting hole spacing, making it ideal for larger drones and load-bearing frames. The angled extended large-area pad design not only improves circuit layout but also simplifies soldering, saving you time and ensuring a clean build.
Weighing just 17 g and sized at 45.5 × 42.5 × 6 mm, the Blueson A2 is compact yet powerful. With support for modern protocols like DShot600, Oneshot, Multishot, and PWM, plus telemetry feedback and galvanometer support, it offers everything advanced pilots need to push performance to the next level.
If you’re looking for a reliable, high-performance ESC that combines power, efficiency, and advanced features in a lightweight package, the SEQURE Blueson A2 is the perfect choice for your racing or freestyle drone.
