Overview

The HAKRC 45A 4-in-1 ESC is a high-performance electronic speed controller designed for competitive FPV racing drones. It features EMF8BB21F16G 8-bit MCU, 45A continuous current per channel, and full support for DShot150/300/600, PWM, Oneshot125/42, and Multishot protocols. With a dual mounting hole design (2020mm and 30.530.5mm), this ESC is compatible with a wide range of FPV frames.

Key Features

• Powerful Hardware: Equipped with an EMF8BB21F16G chip running at 48MHz, imported high-efficiency MOSFETs, and triple-in-one IC drive design.

• Durable Build: 6-layer PCB, 3oz copper thickness, and edge-wrapped solder pads provide excellent heat dissipation and long-term reliability.

• High Integration: Combines 4x 45A ESCs in one compact board with integrated current sensor and advanced SMT components.

• BLHeli-S Native Support: Compatible with BLHeliSuite for full parameter tuning and firmware upgrades.

• Advanced Features: Hardware PWM for smoother motor operation, Damped Light for regenerative braking, precise control, and improved efficiency.

• Protocol Ready: Supports DShot150/300/600 for fast, accurate signal transmission with strong anti-interference performance.

• High-Temp Resilient Wiring: Input/output wires use flexible silicone insulation for better durability and soldering ease.
