Operating principle and design

The Spedix IS20 4in1 controller is an electronic speed control device for brushless motors. It receives signals from the flight controller using modern digital protocols. The EFM8BB21 microcontroller instantly processes the pilot’s commands and supplies voltage to the motor windings. Four channels are combined on one board to save space and weight. The board measures just 31x29mm and fits easily onto a standard 20x20mm rack. This allows you to create ultra-compact racing drones without losing power.

The regulator operates from 2 to 4 lithium polymer cells. Built-in protection prevents overheating and short circuits. High-quality components ensure stable operation under high loads. The holes are designed to accept M2 screws for secure mounting to the frame . The light weight of only 4.9 grams does not weigh down the design of the drone.
