To enable this, reassign two PWM output pins as a serial UART—one for TX and one for RX—via the receiver's Web UI (accessed by putting the receiver into WiFi mode) or via the ExpressLRS LUA script. This enables sensor connectivity while preserving the remaining PWM channels for servos or ESCs.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp style=\"box-sizing: border-box; border-color: rgb(229, 231, 235); outline-color: rgb(0, 0, 255); margin: 0px 0px 25px; color: rgb(28, 29, 29); font-family: Arimo, sans-serif; font-size: 16px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: 0.4px; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: rgb(255, 255, 255); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;\"\u003e\u003cspan style=\"box-sizing: border-box; border-color: rgb(229, 231, 235); outline-color: rgb(0, 0, 255);\"\u003eFor receivers that only provide standard servo pins, an optional adapter cable is available that converts the sensor’s UART connector to two standard servo plugs (TX and RX). \u003c\/span\u003e\u003cspan style=\"box-sizing: border-box; border-color: rgb(229, 231, 235); outline-color: rgb(0, 0, 255);\"\u003e\u003cbr\u003e\n\u003cbr\u003e\n\u003cspan style=\"font-size:18px;\"\u003e\u003cstrong\u003eSensor Configuration \u0026amp; Telemetry Logging\u003c\/strong\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp style=\"box-sizing: border-box; border-color: rgb(229, 231, 235); outline-color: rgb(0, 0, 255); margin: 0px 0px 25px; color: rgb(28, 29, 29); font-family: Arimo, sans-serif; font-size: 16px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: 0.4px; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: rgb(255, 255, 255); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial;\"\u003e\u003cspan style=\"box-sizing: border-box; border-color: rgb(229, 231, 235); outline-color: rgb(0, 0, 255);\"\u003eTo configure this sensor and view telemetry on your EdgeTX radio, install the RadioMaster Sensor Configurator LUA.
