It enables transparent data transmission between devices over Bluetooth using a \u003cstrong\u003eUART interface\u003c\/strong\u003e, allowing data to pass through without any interpretation or modification. \u003cbr\u003e\u003cbr\u003eDesigned for simplicity and reliability, the JDY-31 operates mainly in \u003cstrong\u003etransparent transmission mode\u003c\/strong\u003e and supports standard \u003cstrong\u003eAT commands\u003c\/strong\u003e for configuration and control. As it uses an older Bluetooth version, it may have limitations compared to newer BLE modules in terms of speed and compatibility, but it remains a \u003cstrong\u003ecost-effective and easy-to-use solution\u003c\/strong\u003e for basic Bluetooth serial communication projects.\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eFeatures\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds ls-n\"\u003e\n\u003cli\u003eBluetooth Version: Bluetooth 2.0\u003c\/li\u003e\n\u003cli\u003eSerial pass-through (transparent transmission)\u003c\/li\u003e\n\u003cli\u003eUART communication interface\u003c\/li\u003e\n\u003cli\u003eLow power consumption\u003c\/li\u003e\n\u003cli\u003eSupports standard AT commands\u003c\/li\u003e\n\u003cli\u003eCompact and lightweight design\u003c\/li\u003e\n\u003cli\u003eCost-effective Bluetooth solution\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds ls-n\"\u003e\n\u003cli\u003eModel Name: JDY-31 SPP-C Bluetooth Module\u003c\/li\u003e\n\u003cli\u003eBluetooth Version: 2.0\u003c\/li\u003e\n\u003cli\u003eWorking Frequency Band: 2.4 GHz\u003c\/li\u003e\n\u003cli\u003eCommunication Interface: UART\u003c\/li\u003e\n\u003cli\u003eOperating Voltage: 1.8 – 3.6 V (3.3 V recommended)\u003c\/li\u003e\n\u003cli\u003eVoltage Rating: 1.8 – 3.6 VDC\u003c\/li\u003e\n\u003cli\u003eOperating Temperature: -40 °C to +80 °C\u003c\/li\u003e\n\u003cli\u003eTransmission Distance: Up to 30 meters\u003c\/li\u003e\n\u003cli\u003eMaster-Slave Support: Slave\u003c\/li\u003e\n\u003cli\u003eOperating Current: 4.7 mA\u003c\/li\u003e\n\u003cli\u003eReceiver Sensitivity: -97 dBm\u003c\/li\u003e\n\u003cli\u003eSoldering Temperature: \u0026lt; 260 °C\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePhysical Attributes\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds ls-n\"\u003e\n\u003cli\u003eAntenna Type: Built-in PCB antenna\u003c\/li\u003e\n\u003cli\u003ePCB Color: May vary based on availability\u003c\/li\u003e\n\u003cli\u003eForm Factor: Compact Bluetooth module\u003c\/li\u003e\n\u003cli\u003eWeight: 2 g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eApplications\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds ls-n\"\u003e\n\u003cli\u003eWireless serial communication\u003c\/li\u003e\n\u003cli\u003eEmbedded systems and electronics projects\u003c\/li\u003e\n\u003cli\u003eBluetooth-enabled control systems\u003c\/li\u003e\n\u003cli\u003eDIY and hobbyist projects\u003c\/li\u003e\n\u003cli\u003eBasic automation and monitoring systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePackage Includes\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds ls-n\"\u003e\n\u003cli\u003e1 × JDY-31 SPP-C Bluetooth 2.0 Serial Module\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"KitsGuru","offers":[{"title":"Default Title","offer_id":48627732152572,"sku":"KG1353","price":79.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/Module_1.jpg?v=1767007161","url":"https:\/\/kitsguru.com\/es\/products\/jdy-31-bluetooth-ble-module-without-pin","provider":"KitsGuru","version":"1.0","type":"link"}
