Holybro Tekko32 F4 Metal 4in1 65A ESC (AM32)
by Holybro

The Holybro Tekko32 F4 Metal 4in1 65A ESC (AM32) is a flagship 30.5x30.5mm electronic speed controller built for high-performance 5-inch to 8-inch FPV freestyle, racing, and long-range drones. Equipped with individually metal-cased MOSFETs and a 3 oz copper PCB design, the Tekko32 F4 Metal offers superior thermal dissipation and structural protection while sustaining demanding current draws.

Powered by an F4 processor running at 150MHz and pre-flashed with open-source 32-bit AM32 firmware, this ESC delivers low-latency throttle response, adjustable PWM frequencies from 16kHz to 96kHz, and smooth low-RPM motor startup. Featuring a separated drive and control circuit layout, massive onboard filtering capacitance (2068uF), and support for 4S to 6S LiPo power, it provides continuous 65A (75A burst) per channel for power-hungry brushless setups.

Key Features

• Individual Metal-Cased MOSFETs: Premium metal-enclosed MOSFETs dramatically improve heat dissipation and protect internal components from physical impact.

• High-Speed 150MHz F4 MCU: Upgraded 32-bit processor ensures rapid processing speed and low latency for DShot protocols.

• 3 oz Copper PCB & 2068uF Capacitance: Thick copper traces handle high currents cleanly while massive onboard capacitance filters voltage spikes.

• Pre-Flashed AM32 Firmware: Open-source 32-bit AM32 firmware provides motor efficiency, variable PWM rates, and smooth throttle control.

• 65A Continuous / 75A Burst Rating: Rated for 65A continuous draw per motor channel (75A burst) on 4S to 6S LiPo power.

• Separated Drive & Control Circuits: Separates high-voltage drive stages from control circuitry to minimize electrical noise transferred to flight controller gyros.
