Holybro Tekko32 F4 4in1 50A ESC, 4-6S, 30.5x30.5

The Holybro Tekko32 F4 is a 50 A 4-in-1 ESC for 30.5 x 30.5 mm stacks on 4–6S freestyle, racing and long-range quads. It was one of the first 4-in-1 ESCs to use a 150 MHz F4 MCU, giving quicker, smoother motor control than earlier F3 (108 MHz) and F0 (48 MHz) designs, and it is offered with either AM32 or BLHeli_32 firmware.

Key features

• 50 A continuous and 60 A burst on each of the four channels

• PWM output frequency adjustable from 16 kHz to 96 kHz

• Separate drive and control circuits widen current capability and cut electrical interference reaching the control side

• DShot150/300/600/1200, MultiShot, OneShot, ProShot and PWM, with ESC telemetry

• Onboard analogue current sensor (scale 168) for battery current readings in the flight controller

Specifications

• Continuous current: 50 A x 4

• Burst current: 60 A x 4

• Input voltage: 4–6S LiPo

• MCU: F4, 150 MHz

• Firmware: AM32 or BLHeli_32 (by variant)

• BEC: none

• Current meter scale: 168

• Mounting: 30.5 x 30.5 mm, M4 holes (M3 grommets included)

• Weight: 13.8 g

• In the box: ESC, 4 x M3 anti-vibration grommets, 1000 µF 35 V capacitor, 8-pin to 8-pin 1 mm pitch cables (65 mm and 25 mm)

With no onboard BEC, the flight controller needs its own regulator. Solder the supplied 1000 µF capacitor across the battery pads to absorb voltage spikes, and check the 8-pin harness pinout against your flight controller before plugging in.
