With AM32 firmware, the Sequre Blueson A1 is a great choice for a high-voltage 20x20 4-in-1 ESC, supporting 2-6S voltage input, 65A continuous current, and a wide PWM frequency range from 8KHz to 128KHz, powered by an AT32F421 processor.
Features:
- 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.
- 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.
- Supports 6S/8S wide range voltage input, allowing your aircraft to adapt to power batteries of different specifications, improving the versatility of the device.
- With 20*20mm installation hole spacing, it is tailor-made for racing drones and easy to install.
- ESC reserves a large area of solder pad to effectively reduce the difficulty of soldering.
