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.\u003c\/p\u003e\n\u003ch3\u003eKey Highlights\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e150MHz F4 Processing Power:\u003c\/strong\u003e Drastically outperforms legacy F3 (108MHz) and F0 (48MHz) MCUs for ultra-fast motor response and zero control lag.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNative AM32 Open-Source Firmware:\u003c\/strong\u003e Pre-flashed with target AM32_TEKKO32_4IN1_F421; adjust settings easily via the \u003ca href=\"https:\/\/am32.ca\/\"\u003eAM32 portal\u003c\/a\u003e or directly using the web-based \u003ca href=\"https:\/\/am32.ca\/configurator\"\u003eAM32 configurator\u003c\/a\u003e.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGalvanic Isolation Architecture:\u003c\/strong\u003e Features separate drive and control circuits, expanding current-handling headroom while shielding sensitive logic lines from high-voltage motor electrical interference.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0914\/9972\/5181\/files\/Tekko32F44in150AESC_AM32_13_1800x1800_1fb7eec8-a688-4292-81af-9b2fb4daffc0.webp?v=1784805833\" alt=\"\"\u003e\u003c\/p\u003e\n\u003ch3\u003eWhy You Want It\u003c\/h3\u003e\n\u003cp\u003eIf 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.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eContinuous Current:\u003c\/strong\u003e 50A × 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBurst Current:\u003c\/strong\u003e 60A × 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Voltage:\u003c\/strong\u003e 4–6S LiPo\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMCU:\u003c\/strong\u003e F4 MCU @ 150MHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePWM Frequency Range:\u003c\/strong\u003e 16kHz to 96kHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFirmware Target:\u003c\/strong\u003e AM32_TEKKO32_4IN1_F421\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupported Protocols:\u003c\/strong\u003e DShot 150\/300\/600\/1200, MultiShot, OneShot, Proshot, PWM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent Sensor:\u003c\/strong\u003e Onboard analog (Scale ratio: 120 - V1.9 Version)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eESC Telemetry:\u003c\/strong\u003e Supported\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBEC Output:\u003c\/strong\u003e No output BEC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Pattern:\u003c\/strong\u003e 30.5 x 30.5mm (M4 holes, M3 silicone anti-vibration grommets included)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 48 x 37 x 6 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 13.8g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003ch4\u003eWhat firmware does the Holybro Tekko32 F4 4in1 50A ESC use?\u003c\/h4\u003e\n\u003cp\u003eThe Tekko32 F4 comes pre-flashed with open-source AM32 firmware using the AM32_TEKKO32_4IN1_F421 target.
