This high-frequency (863-928MHz) version is specifically tuned for regions utilizing the 915MHz ISM band, ensuring optimal signal penetration through dense urban environments and rugged outdoor terrains. Whether you are building a decentralized text-messaging network for hiking or deploying remote agricultural sensors, this board provides the reliable, long-range backbone your project demands.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2 class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eBuilt for Solar-Powered Meshtastic Nodes\u003c\/span\u003e\u003c\/h2\u003e\n\u003cp class=\"ng-star-inserted\"\u003e\u003cspan class=\"ng-star-inserted\"\u003eThis V4 iteration completely overhauls power management by introducing a dedicated 1.25-2P solar input interface (4.7-6V) alongside the standard lithium battery port. This allows developers to deploy truly autonomous, self-sustaining Meshtastic nodes on rooftops or mountain peaks without worrying about frequent battery replacements. Combined with the energy-efficient ESP32-S3FN8 dual-core processor and a crisp 0.96-inch OLED display, it offers a complete, out-of-the-box hardware solution for off-grid mesh networking.\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 ensure you are using Meshtastic firmware version 2.7.20 or above for this V4.3 hardware, and strictly avoid selecting the \"Meshtastic UI\" option during flashing. Our Sham Shui Po technical team frequently sees customers with blank OLED screens because the \"Meshtastic UI\" setting is designed exclusively for touchscreen models, not the standard 0.96-inch OLED included on this board.\u003c\/span\u003e\u003c\/p\u003e","brand":"Heltec","offers":[{"title":"with GPS","offer_id":48176971088023,"sku":"21CU000180","price":295.0,"currency_code":"HKD","in_stock":true},{"title":"no GPS","offer_id":48176971120791,"sku":"21CU000167","price":250.0,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0440\/4022\/4919\/files\/heltec-wifi-lora-32-v4-esp32-main.jpg?v=1787995577","url":"https:\/\/scccltd.com\/products\/heltec-wifi-lora-32-v4-esp32-s3-board-863-928mhz-meshtastic-node","provider":"Sun Cheong Computer Company Limited","version":"1.0","type":"link"}
