Overview
About Holybro Tekko32 F4 50A 4-in-1 ESC.
The Holybro Tekko32 F4 50A 4-in-1 ESC packs four high-current brushless speed controllers onto one board built around a fast F4 MCU running at 150MHz. It runs the BLHeli_32 ecosystem (also available with AM32 firmware) and supports the full range of modern protocols including DShot 150/300/600/1200 plus MultiShot, OneShot, ProShot and PWM. ESC telemetry is supported, letting the flight controller read RPM, temperature and current for advanced features like RPM-based filtering.
It delivers 50A continuous per channel with 60A bursts and is built for 4-6S LiPo input, targeting powerful 5-inch and larger builds. A separate drive-and-control circuit broadens current capability, an onboard analog current sensor reports draw to the flight controller, and an included 1000uF 35V capacitor filters voltage spikes. The board mounts on the standard M4 30.5 x 30.5mm pattern, weighs about 13.8g and ships with anti-vibration grommets.
Aimed at experienced FPV pilots and demanding builders, the Tekko32 F4 suits high-performance freestyle, racing and long-range quads where the flexibility of BLHeli_32/AM32 firmware, full DShot support and telemetry are valued. It is a premium, vendor-neutral 4-in-1 from an established manufacturer, well suited to anyone wanting maximum tuning control over their propulsion.

Buying guide
How to choose.
Choose the Tekko32 F4 when you want the flexibility and tuning power of BLHeli_32 or AM32 firmware, full DShot support up to DShot1200, and ESC telemetry for RPM-based filtering. These features make a real difference on high-performance and long-range builds where smoothness and precise tuning matter. Confirm the M4 30.5 x 30.5mm mounting fits your stack.
Rated at 50A continuous and 60A burst per channel on 4-6S, it comfortably drives modern 5-inch motors on 6S and has headroom for demanding flying. Keep sustained motor current below 50A per channel and ensure airflow over the board; the separate drive-and-control circuit helps sustain high current, but heat management is still important under hard use.
Note there is no BEC, so supply regulated power to your flight controller from the stack or a separate source as your FC requires. If you only need basic DShot300/600 and want to save money, a BLHeli_S 4-in-1 is sufficient; but for telemetry, RPM filtering and the highest protocol versions, the Tekko32 F4 is a premium, well-supported choice available in India.
FAQ
Common questions.
What firmware does the Tekko32 F4 use?
It is part of the BLHeli_32 ecosystem and is also offered with AM32 firmware on its F4 150MHz MCU. Both support full DShot protocols and ESC telemetry, giving you extensive tuning options and features such as RPM-based filtering that BLHeli_S boards cannot provide.
Does it support ESC telemetry?
Yes. It supports ESC telemetry, sending data such as RPM, temperature and current to your flight controller. This enables advanced features like RPM filtering for smoother flight and better motor monitoring, which is a key reason builders choose BLHeli_32 or AM32 ESCs over BLHeli_S.
What battery voltage can I run?
It is built for 4-6S LiPo input, suiting powerful 5-inch and larger builds. With 50A continuous and 60A burst per channel it has ample current capacity for 6S motors. Keep sustained motor draw below 50A per channel for reliable, cool operation.
Does it have a BEC?
No, the Tekko32 F4 does not provide a BEC output. Your flight controller must be powered from the stack connection or another regulated source as required by your FC. Most 30x30 flight controllers handle their own voltage regulation, so this is rarely an issue in a stack.
What DShot versions does it support?
It supports the full range: DShot 150, 300, 600 and 1200, plus MultiShot, OneShot, ProShot and PWM. This makes it future-proof for current flight controller firmware and lets you choose the protocol that best matches your build and tuning preferences.
Will it fit a standard 30x30 stack?
Yes. It uses the M4 30.5 x 30.5mm mounting pattern, the standard for full-size FPV stacks, and includes anti-vibration grommets. It pairs with most 30x30 flight controllers via the included 8-pin to 8-pin cable, making it a flexible choice across many builds.
