HAKRC BLHeli_32 3220 65A 4-in-1 ESC for 20x20mm Mount 2S–8S FPV Racing and Freestyle Drones

The HAKRC BLHeli_32 3220 65A 4-in-1 ESC is a high-performance electronic speed controller engineered for demanding FPV drones. Featuring an 8-layer, 2oz copper PCB, this ESC offers superior current handling and heat dissipation. The board supports 2S–8S LiPo input and delivers a continuous current of 65A (burst up to 70A), ensuring stable power for high-thrust setups.

With the AT32F421 main control chip running at 128MHz, imported Japanese MOSFETs, FD6288Q 3-in-1 IC drivers, and Murata capacitors, this ESC is built for durability and performance. The PCB uses a high-end resin plug-hole process and dual-pad design with full metallized edge protection to prevent solder pad detachment. It also supports popular protocols including PWM, Oneshot125, Oneshot42, Multishot, DShot150/300/600, and includes advanced features like Damped Light mode for quieter, smoother response and better braking.
