SEQURE Blueson A2 65A 4-in-1 ESC
Description:
High-quality ultra-high copper thickness PCB ensures the current carrying capacity while improving heat dissipation. Equipped with top-level MOSFET, it enhances flight performance and makes you enjoy the fun of flying in the air.
(2) Equipped with a high-speed 32-bit processor, it supports full-segment dynamic PWM variable refresh rate of 8KHz-128KHz, with more precise speed response and smoother throttle control.
(3) Supports 6S/8S wide range voltage input, allowing your aircraft to adapt to power batteries of different specifications, improving the versatility of the device.
(4) 30.5mm installation hole spacing is more suitable for large-sized load-type flight vehicles and is easy to install.
(5) The angled extended large-area pad design not only makes the motor circuit layout more refined, but also effectively simplifies the welding process.
