Botlab Dynamics BotDrive AM32 4-in-1 ESC 55A

The Botlab Dynamics BotDrive 55A is a 4-in-1 electronic speed controller designed for 5-inch freestyle, racing, and mid-range builds running on 2-6S LiPo power. Built around the open-source AM32 firmware ecosystem, it delivers smooth throttle resolution, robust desync protection, and extensive tuning options without the licensing constraints of older closed-source protocols.

Key features

• Handles 55A continuous current per channel to support demanding high-kV motor setups.

• Pre-flashed with open-source AM32 firmware for advanced telemetry, variable PWM frequency, and precise motor timing.

• Native 4-in-1 architecture streamlines harness wiring for cleaner, more compact stack builds.

• Broad 2-6S LiPo voltage compatibility suits both lightweight racing rigs and heavier freestyle quads.
