Поделиться ссылкой
The RADIOMASTER ER series of PWM receivers is based on the revolutionary ELRS (ExpressLRS) system. They offer high performance, high reliability, a flexible configuration, fast response speed, and ultra-long range, bringing you the very best in this technology. The other feature of this tiny receiver is the capability to accept an input voltage of 4.5~8.4V, and it automatically detects either the receiver voltage telemetry or the external battery voltage telemetry.
The ER4 PWM receiver can drive 4 servos simultaneously and is very compact and lightweight. This makes them suitable for small airplanes, small boats, small cars, and any other models that require a small, lightweight receiver while still providing full range.
