Holybro Tekko32 F4 4in1 50A ESC (30x30)

Looking to buy the Holybro Tekko32 F4 4in1 50A ESC in the UK? Since BLHeli_32 folded, open-source 32-bit speed has found its true home. This 30x30 4in1 ESC pairs a screaming 150MHz F4 MCU with native AM32 firmware to wipe out motor desyncs and throttle delay on 4S to 6S quadcopters. Supporting variable 16kHz–96kHz PWM frequencies and DShot1200 protocol execution, it keeps your Betaflight PID loop clean without overloading processor cycles. Backed by our 10 years of experience in the manufacturing and delivery of commercial FPV systems at Unmanned Tech, we bring you battle-tested hardware built to survive hard crashes while keeping the magic smoke safely trapped inside your MOSFETs.

Key Highlights

• 150MHz F4 Processing Power: Drastically outperforms legacy F3 (108MHz) and F0 (48MHz) MCUs for ultra-fast motor response and zero control lag.
• Native AM32 Open-Source Firmware: Pre-flashed with target AM32_TEKKO32_4IN1_F421; adjust settings easily via the AM32 portal or directly using the web-based AM32 configurator.
• Galvanic Isolation Architecture: Features separate drive and control circuits, expanding current-handling headroom while shielding sensitive logic lines from high-voltage motor electrical interference.

Why You Want It

If you've spent one too many late nights nursing a soldering iron burn while staring blankly at Betaflight motor tabs trying to hunt down mid-throttle oscillations, the Tekko32 F4 is your ticket off the pain train. Holybro built this 30.5x30.5mm stack unit with physical separation between its high-power drive circuits and delicate logic controller. Pushing up to 96kHz PWM output, it makes your motors run noticeably smoother, cooler, and quieter across aggressive 6S freestyle flips and race gates. With a rating of 50A continuous (60A burst per channel), native telemetry, and an onboard analog current sensor, your OSD readout stays accurate down to the final battery cell drop.

FAQ

What firmware does the Holybro Tekko32 F4 4in1 50A ESC use?

The Tekko32 F4 comes pre-flashed with open-source AM32 firmware using the AM32_TEKKO32_4IN1_F421 target. You can customize motor timing, rotation, and PWM parameters via Betaflight passthrough on Chromium browsers using the web-based AM32 configurator.

What’s in the Box*

• 1× Holybro Tekko32 F4 4in1 50A ESC
• 4× M3 Anti-Vibration Silicone Grommet Inserts
• 1× 1000uF 35V Electrolytic Capacitor
• 1× 8-pin to 8-pin 1mm Pitch 65mm Cable

Disclaimer

Hint: Always use a power filter device with TVS diodes when pairing this ESC with low KV motors or running high-voltage 6S setups to guard against inductive voltage spikes. We strongly advise soldering the included 1000uF 35V capacitor directly to the main XT60 battery pads before applying power.

Still Here?

You could easily waste another three hours reading Discord flame wars about BLHeli_32 vs AM32 or re-watching your last desync crash in slow motion, but your quad frame isn't going to build itself. Grab this 150MHz F4 powerhouse today, solder those motor leads clean, and let us pay our UK light bill.
