RadioMaster ERS Sensor UART to Dual PWM Adapter

Price: 3.95

Connect your ERS sensor to most PWM ExpressLRS receiver—even those without a dedicated UART port. This compact PCB adapter converts the sensor’s female JST-GH UART connector into two outputs: a standard servo-style plug and a single-pin Dupont signal line, allowing connection to two PWM channels.

For receivers without a plug-and-play UART, reassign two PWM outputs as TX and RX using the receiver’s Web UI (WiFi mode) or the ExpressLRS LUA script. This enables full sensor functionality while keeping remaining PWM channels free for servos or ESCs.
