Radiomaster ER5A V2 ELRS PWM (5ch)

The Radiomaster ER5A V2 is a compact PWM receiver for the ELRS system operating at 2.4GHz. With five PWM outputs, it is primarily intended for aircraft models or RC cars. The ER5A receiver features a single antenna and 10mW telemetry power. It also includes a power supply voltage sensor and a main battery voltage sensor, capable of measuring voltages in the range of 4–35V. Through telemetry, it can transmit information about the receiver supply voltage or the main battery voltage. The receiver can be powered in the range of 4.5–8.4V, supporting direct connection of a 2S battery. Configuration is easy via Wi-Fi and WebUI, allowing setup without the need for a physical connection.
