HelloRadio HR7E 2.4GHz ELRS is an ExpressLRS receiver with PWM outputs, designed for RC airplanes, boats and other models controlled by servos directly from the receiver. It offers 8 PWM channels and two 18cm antennas for reliable reception.
The receiver also features a UART for connecting external sensors with the CRSF protocol. There is also a dedicated connector for battery voltage monitoring of the propulsion battery in the range of 4–35V. Telemetry power is up to 100 mW. Setup and firmware updates are performed via WiFi. It is recommended to place the antennas perpendicular to each other and away from metal and carbon parts of the model.
