Operating principle and design

The SPEDIX ES20 Lite controller is an electronic speed control device for brushless motors. It receives signals from the flight controller using modern digital protocols. The high-performance EFM8BB21 microcontroller instantly processes the pilot's commands. The regulator then supplies the motor windings with precisely calculated voltage and current. This happens hundreds of times per second to ensure perfect rotation synchronization.

SPEDIX engineers used only high-quality components from leading global manufacturers. The regulator uses original parts from STMicroelectronics from Switzerland, TDK from Japan and AVX from the USA. The board is made with 3 Oz gold plating for extremely low resistance. A specialized driver chip ensures excellent response speed to all pilot commands.

Specifications and protocols

Explore the detailed parameters of the SPEDIX ES20 Lite controller. The board dimensions are only 10.5 mm long, 24 mm wide and 5 mm high. The weight of the device does not exceed 4.9 grams.

Input voltage from 2 to 4 LiPo cells, corresponding to 7.4–14.8 Volts. The continuous operating current is 20 amperes. The EFM8BB21 microcontroller provides fast signal processing.

The controller supports all modern control protocols. These are Dshot600, Dshot300, Dshot150 for digital communication. Oneshot125, Oneshot42, Multishot and standard PWM are also available. The BLHeli_S firmware is easily configured using special software.

Wires with a cross-section of 20 AWG are used for connection. The regulator does not have a built-in BEC, which reduces weight and improves reliability .
