Product details
The RadioMaster ER5A V2 is a compact 2.4GHz ExpressLRS receiver with five PWM outputs, designed for fixed-wing aircraft, surface vehicles and traditional RC models that don't need digital SBUS or CRSF protocols. It drives up to five servos and automatically detects external battery or receiver/BEC voltage.
Key features
- Five independent PWM channels for direct servo and brushed ESC control without a flight controller
- Built-in TCXO (temperature-compensated crystal oscillator) for stable, accurate performance across environments
- Wi-Fi updates and WebUI configuration, plus automatic voltage telemetry reporting over a 4.0-35 V range
- High-sensitivity antenna running ExpressLRS 3.3.0 firmware pre-installed
- Compact 37.0 x 19.3 x 13.0 mm footprint at 6.7 g, powered from 4.5-8.4 V DC
The ER5A V2 binds to any 2.4GHz ExpressLRS transmitter and works with traditional RC planes, crawlers and boats needing PWM output. Not compatible with Betaflight or other digital flight-controller ecosystems — use an ER-series receiver with CRSF output for quadcopters.
