The RPM \u0026amp; Telemetry Signal Coupler Module works with an existing ESC RPM or telemetry signal and helps another device recognize that signal more reliably.\n\u003c\/p\u003e\n\n\u003ch3 style=\"font-size: 15px; font-weight: bold; margin: 14px 0 8px; color: #000;\"\u003eIs this an ESC programmer?\u003c\/h3\u003e\n\u003cp\u003e\nNo. It is not an ESC programmer or programming card. It is a signal coupling module for RPM and telemetry signal paths.\n\u003c\/p\u003e\n\n\u003ch3 style=\"font-size: 15px; font-weight: bold; margin: 14px 0 8px; color: #000;\"\u003eWhere does the ESC connect?\u003c\/h3\u003e\n\u003cp\u003e\nThe ESC connects to the “ESC IN” end of the module. The “Signal OUT” end connects to the receiver, gyro, flybarless system, or compatible electronics.\n\u003c\/p\u003e\n\n\u003ch3 style=\"font-size: 15px; font-weight: bold; margin: 14px 0 8px; color: #000;\"\u003eDoes the module need power?\u003c\/h3\u003e\n\u003cp\u003e\nYes. Both the ESC IN end and the Signal OUT end need to be powered through their respective VCC ports. The acceptable voltage range is 3.3V–12V.\n\u003c\/p\u003e\n\n\u003ch3 style=\"font-size: 15px; font-weight: bold; margin: 14px 0 8px; color: #000;\"\u003eCan it be used only with Hobbywing ESCs?\u003c\/h3\u003e\n\u003cp\u003e\nThe manual describes it as a general product that is not only applicable for Hobbywing ESCs, but may also be used with ESCs from other brands when the signal, voltage, and wiring requirements match.\n\u003c\/p\u003e\n\n\u003ch3 style=\"font-size: 15px; font-weight: bold; margin: 14px 0 8px; color: #000;\"\u003eWhen should I consider using this module?\u003c\/h3\u003e\n\u003cp\u003e\nConsider it when your ESC already outputs RPM or telemetry data, but the flybarless system, receiver, gyro, or compatible device cannot recognize the signal correctly or the data transmission is unstable.\n\u003c\/p\u003e","brand":"ChinaHobbyLine","offers":[{"title":"Global","offer_id":48554372038870,"sku":"RPMTelemetry GL","price":10.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0633\/0617\/0582\/files\/1_c35ba745-60a9-49d7-89aa-3d920c962336.jpg?v=1783478762","url":"https:\/\/chinahobbyline.com\/ru\/products\/hobbywing-rpm-telemetry-signal-coupler-module","provider":"ChinaHobbyLine","version":"1.0","type":"link"}
