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.\u003c\/p\u003e\u003cp\u003eFor 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.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConnects an ERS sensor to PWM ExpressLRS receivers via two PWM channels (TX\/RX reassignment).\u003c\/li\u003e\n\u003cli\u003eJST-GH UART input to dual outputs: 3-pin servo-style plug + 1-pin Dupont signal line.\u003c\/li\u003e\n\u003cli\u003eCompact inline harness format for tidy installations.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eItem\u003c\/td\u003e\n\u003ctd\u003eERS Sensor UART to Dual PWM Adapter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConnector type\u003c\/td\u003e\n\u003ctd\u003eJST-GH to 3p Servo \/ 1p Dupont\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSize\u003c\/td\u003e\n\u003ctd\u003e85mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e1.81g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVisible PCB marking\u003c\/td\u003e\n\u003ctd\u003eSENSOR-CON V1.0 (also shows: 7098400_Y870, 260114)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch2\u003eWhat’s Included\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e1 * ERS Sensor UART to Dual PWM Adapter\u003c\/li\u003e\n\u003cli\u003e2 * Clear shrink tube\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eAdding ERS sensor UART connectivity to PWM ExpressLRS receivers without a dedicated UART port\u003c\/li\u003e\n\u003cli\u003eRC aircraft, multirotors, or robotics builds that need UART sensor integration while preserving remaining PWM outputs\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eFor setup questions and compatibility guidance, contact support at \u003ca href=\"https:\/\/rcdrone.top\/\"\u003ehttps:\/\/rcdrone.top\/\u003c\/a\u003e or email \u003ca href=\"mailto:support@rcdrone.top\"\u003esupport@rcdrone.top\u003c\/a\u003e.\u003c\/p\u003e\u003ch2 id=\"details\"\u003eDetails\u003c\/h2\u003e\u003cdiv class=\"details-gallery\"\u003e\n\u003cimg alt=\"ERS Sensor UART to Dual PWM Adapter harness connecting JST-GH UART sensor lead to two PWM-style outputs\" loading=\"lazy\" src=\"https:\/\/rcdrone.top\/cdn\/shop\/files\/ERS-Sensor-UART-to-Dual-PWM-Adapter.jpg?v=1780651526\"\u003e\u003cp\u003eConvert an ERS sensor JST-GH UART connection into two PWM-channel leads so TX\/RX can be reassigned on PWM ExpressLRS receivers.\u003c\/p\u003e\n\u003cimg alt=\"Close-up of SENSOR-CON V1.0 inline PCB with 85mm harness and dual signal leads (3-pin servo-style + 1-pin Dupont)\" loading=\"lazy\" src=\"https:\/\/rcdrone.top\/cdn\/shop\/files\/ERS-Sensor-UART-to-Dual-PWM-Adapter_28ec8392-fa48-49d4-85bb-af9246719136.jpg?v=1780651533\"\u003e\u003cp\u003eAn 85mm inline harness keeps wiring tidy while breaking UART out to a standard servo-style plug plus a single Dupont signal lead.\u003c\/p\u003e\n\u003cimg alt=\"Adapter cable and small PCB placed on a digital scale to illustrate compact, lightweight inline design\" loading=\"lazy\" src=\"https:\/\/rcdrone.top\/cdn\/shop\/files\/ERS-Sensor-UART-to-Dual-PWM-Adapter_1370d235-e933-47fe-b9ac-bf0e651ceeb0.jpg?v=1780651540\"\u003e\n\u003c\/div\u003e","brand":"RadioMaster","offers":[{"title":"Default Title","offer_id":52968273608928,"sku":"RM0157.ERS-ADPTR-1","price":7.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0643\/3210\/3904\/files\/7_83bcf795-4d32-4fa8-8612-0d20595d2e08.jpg?v=1780585672","url":"https:\/\/rcdrone.top\/sw\/products\/radiomaster-ers-uart-pwm-adapter","provider":"RCDrone","version":"1.0","type":"link"}
