Equipped with a powerful internal LWIP protocol and simple AT command support, it dramatically reduces development time for IoT applications. Whether you are building a smart weather station, remote relay switch, or wireless sensor network, this module acts as a reliable bridge between your microcontroller and the cloud.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2 class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eUpgraded ESP-01S PCB Antenna Design\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eThe ESP-01S is a direct optimization of the classic ESP-01, featuring a refined PCB antenna layout that significantly enhances signal strength and stability. When properly matched and operated in an open environment, this upgraded antenna design can achieve a wireless transmission distance of up to 400 meters. Its ultra-compact 24x9mm footprint ensures it can be easily integrated into space-constrained enclosures without sacrificing network performance.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003ePro Tip from Our Technicians\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eAlways power this module with a dedicated 3.3V power supply capable of delivering at least 250mA during peak transmission. Our Sham Shui Po DIY specialists strongly warn against connecting the VCC pin directly to the 5V pin of an Arduino UNO, as this will instantly destroy the ESP8266 chip. Additionally, you must use a logic level converter for the TX\/RX serial lines if you are interfacing it with a 5V microcontroller.\u003c\/span\u003e\u003c\/p\u003e","brand":"Sun Cheong Computer Company Limited","offers":[{"title":"Default Title","offer_id":48187478868119,"sku":"21TS001392","price":29.0,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0440\/4022\/4919\/files\/esp8266-esp-01s-wifi-module-top-view..jpg?v=1788252255","url":"https:\/\/scccltd.com\/products\/esp8266-esp-01s-wifi-transceiver-module","provider":"Sun Cheong Computer Company Limited","version":"1.0","type":"link"}
