Product overview
The RadioMaster ER6 2.4GHz ELRS PWM Receiver is a radio-control component with six PWM channels capable of driving up to six servos. CRSF and Sbus serial outputs extend its connection options, while a four-wire CRSF interface supports later telemetry-sensor expansion. ExpressLRS 3.3.0 is pre-installed, with Wi-Fi updates and WEBUI configuration available for setup and maintenance. Its radio interface supports 2.4GHz ExpressLRS modules and transmitters with built-in 2.4GHz ExpressLRS. Built-in telemetry monitors receiver or external battery voltage and automatically detects which voltage input to use.
A one-piece molded shell houses the receiver, which measures 43*25*15mm and weighs 14.5 grams. Installation must accommodate its 20cm high-sensitivity dual antennas and 2.54 mm connectors. The receiver requires DC 4.5 - 8.4V power; its separate battery-voltage telemetry input detects DC 4.0 - 35V. Telemetry power is LUA adjustable up to a maximum of 100mw. The supplied configuration comprises one ER6 receiver, one Type-B voltage telemetry wire, one CRSF wire, one ELRS-RX-SBUS wire and one user card, providing the receiver and listed connection accessories for integration.
