SEQURE SQESC 28120 Brushless ESC 2–8S Power Supply (AM32) + 10A BEC
The SEQURE SQESC 28120 is a powerful and versatile brushless electronic speed controller designed for demanding hobby applications. Built around a high-performance 32-bit STM32G071 processor running at up to 64 MHz, it delivers fast response, stable operation, and broad compatibility with popular control protocols and tuning options. Whether you're building a multirotor drone, RC plane, boat, car, crawler, or helicopter, this ESC is made to handle high current loads with confidence.
Thanks to efficient MOSFETs and a CNC-machined metal heatsink, the SQESC 28120 offers excellent heat dissipation under heavy load, helping maintain reliable continuous performance. The adjustable 10A BEC adds even more flexibility, allowing you to directly power receivers, servos, and other onboard electronics without needing an additional power solution.
