The Holybro Tekko32 F4 4-in-1 50A ESC combines four ESCs into one board and reduces wiring complexity. The page describes a high-performance 50A ESC for smooth and efficient motor control in multirotor drones with advanced firmware for precise throttle response.
The specifications give a burst current of 60A, a weight of 13.8 g, DShot 150/300/600/1200, MultiShot, OneShot, ProShot and PWM protocols and an M4 30.5 x 30.5 mm mounting pattern with M3 grommets included. At the time of the check the page showed it as sold out (SKU TIFAC0244).
4-in-1 design: four controllers in one board.
50A ESC: for multirotor drones.
60A burst: as listed.
DShot150/300/600/1200, MultiShot, OneShot, ProShot, PWM: supported protocols.
Optimised thermal design: for stable operation.
13.8 g: 30.5 x 30.5 mm mounting.
An electronic speed controller (ESC) converts the throttle signal from the flight controller into the three-phase power that a brushless motor needs. It switches battery current through MOSFETs at high speed, so the motor turns at the speed that the pilot or autopilot asks for. The continuous current rating shows how much current the ESC can carry all the time, and the burst rating shows what it can survive for a few seconds.
Match the ESC to the rest of the power system. The battery cell count must fall inside the listed range, the continuous current must be higher than what your motor and propeller draw at full throttle, and the signal protocol (for example PWM, Oneshot, Multishot or DShot) must be supported by your flight controller. An ESC marked OPTO has no built-in BEC, so the receiver and flight controller need power from another source. An ESC with a BEC can supply a regulated voltage, usually 5V, to small electronics.
Install and test carefully. Solder joints must be clean and strong, the motor wires should be kept short and tidy, and the ESC needs airflow because current makes heat. Calibrate the throttle range if the ESC needs it, check the motor direction with the propellers removed, and never connect a battery with the propellers fitted while you are working on the wiring. Use a battery with a cell count and connector that suit the ESC, and check for a heat problem after a short test hover.

The mounting is M4 30.5 x 30.5 mm with M3 grommets included. The kit includes a 1000uF 35V capacitor and two 8-pin connector cables (65 mm and 25 mm).
The page gives the continuous rating only in the title (50A) and does not list a cell range, so check the pack range with the seller.
