Hakrc 3B40A 2S-6S 4in1 FPV ESC

High-Performance Core: Speed and Reliability

At the heart of the 3B40A ESC lies a potent AT32F421 main control chip, clocked at 128MHz for lightning-fast signal processing and immediate throttle response. Paired with an efficient FD6288Q IC driver, it ensures robust power delivery. Premium imported Murata capacitors guarantee stable operation and longevity under harsh conditions.

Built Tough: Durable Design for Demanding Flights

The HAKRC 3B40A is constructed for durability with a high-end resin plug-hole PCB process. Metallized edging on solder pads prevents lifting during intense flights or crashes. Its 6-layer PCB with 3-ounce copper thickness enhances structural integrity, heat dissipation, and operational efficiency.

Smart Firmware & Broad Protocol Support for Tuned Flight

Powered by BLHeli_S (G_H_30) firmware, the 3B40A offers a stable, feature-rich platform, customizable via CleanFlight and BetaFlight. It supports PWM, Oneshot125, Oneshot42, Multishot, Dshot150, Dshot300, and Dshot600 protocols, ensuring robust anti-interference and precise signal transmission.

Optimized Flight Characteristics for FPV Dominance

The HAKRC 3B40A incorporates advanced technologies to elevate FPV experience:

• Hardware PWM: Cleaner signals reduce noise for smoother throttle response.
• Damped Light Mode: Regenerative braking enhances precise maneuvers.
