ERS Sensor UART to Dual PWM Adapter for PWM ExpressLRS Receiver | JST-GH to 3p Servo + 1p Dupont

Overview

This adapter converts an ERS sensor JST-GH UART connection into two PWM-channel connections for PWM ExpressLRS receivers that do not have a dedicated UART port. It breaks out the sensor UART into a standard 3-pin servo-style plug and a 1-pin Dupont signal lead, enabling the use of two PWM outputs as TX and RX while keeping other PWM channels available for servos or an ESC.

For receivers without plug-and-play UART support, two PWM outputs can be reassigned as TX and RX using the receiver Web UI (WiFi mode) or the ExpressLRS LUA script to enable full sensor functionality.

Key Features

• Connects an ERS sensor to PWM ExpressLRS receivers via two PWM channels (TX/RX reassignment).
• JST-GH UART input to dual outputs: 3-pin servo-style plug + 1-pin Dupont signal line.
• Compact inline harness format for tidy installations.

Details

Convert an ERS sensor JST-GH UART connection into two PWM-channel leads so TX/RX can be reassigned on PWM ExpressLRS receivers.

An 85mm inline harness keeps wiring tidy while breaking UART out to a standard servo-style plug plus a single Dupont signal lead.
