SpeedyBee F405 OX32 55A 4 in 1 ESC

The SpeedyBee OX32 55A 4-in-1 ESC is a high-performance 32-bit electronic speed controller engineered for aggressive freestyle, racing, and cinematic FPV builds. Running SpeedyBee's custom OX32 firmware, this ESC provides high-resolution throttle response, full telemetry output, and robust 3-6S power delivery. Originally developed for the F405 V5 stack, it features a dual-sided aluminium alloy heatsink with nickel-plated bus bars to efficiently manage thermal loads during heavy punch-outs, making it a reliable drop-in upgrade for any 30.5x30.5mm drone frame.

Key features

• 32-Bit OX32 Firmware: Dedicated 32-bit architecture ensures seamless DShot300 and DShot600 communication with comprehensive ESC telemetry support.

• Genuine 55A Output: Delivers 55A of continuous current per channel with 70A bursts to confidently drive power-hungry 6S motors.

• Dual-Sided Heatsink: An integrated aluminium alloy heatsink protects the MOSFETs and rapidly dissipates heat during demanding flights.

• Advanced Power Filtering: Includes an onboard TVS diode to absorb voltage spikes and a 1000µF low-ESR solid capacitor for ultra-clean power delivery.

• Accessible Mounting: Built around an industry-standard 30.5x30.5mm pattern with side-opening M4 cutouts to simplify stacking and installation.

When wiring this ESC to a flight controller, standard DShot600 is recommended for optimal performance. While it perfectly replaces the ESC in a SpeedyBee V5 stack, it easily pairs with any modern FC using the provided wiring harness or direct soldering pads. Always solder the included 1000µF capacitor directly to the main battery input pads to protect your electronics against damaging reverse voltage spikes.
