{"product_id":"gsm-sim800l","title":"GSM SIM800L","description":"\u003cp\u003eThe SIM800L is a miniature quad-band GSM\/GPRS module with TTL serial interface — no MAX232 required. Supports SMS, voice calls, and GPRS data (TCP\/IP) globally. Includes two antennas: a wire antenna (soldered to NET pin) and a PCB antenna with IPX connector for use inside enclosures. Onboard network status LED (slow blink = signal, fast blink = no signal).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCaution:\u003c\/strong\u003e The SIM800L uses 2.8V logic. Use a resistor voltage divider when interfacing the TX line with 5V Arduino to avoid damaging the module.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eModule: SIM800L\u003c\/li\u003e\n\u003cli\u003eBands: Quad-band GSM\/GPRS 850\/900\/1800\/1900MHz\u003c\/li\u003e\n\u003cli\u003eSupply Voltage: 3.7–4.2V DC\u003c\/li\u003e\n\u003cli\u003ePeak Current: 2A\u003c\/li\u003e\n\u003cli\u003eInterface: TTL UART (direct MCU connection)\u003c\/li\u003e\n\u003cli\u003eAntennas: Wire (NET pin) + PCB antenna with IPX pigtail\u003c\/li\u003e\n\u003cli\u003eOnboard: Network status LED\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cstrong\u003eApplications:\u003c\/strong\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eIoT SMS and GPRS data projects\u003c\/li\u003e\n\u003cli\u003eRemote monitoring and control\u003c\/li\u003e\n\u003cli\u003eGPS tracker and vehicle tracking systems\u003c\/li\u003e\n\u003cli\u003eMicrocontroller-based GSM communication\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Powered by INFINITY WORKS","offers":[{"title":"Default Title","offer_id":47371686019126,"sku":"TW179","price":354.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0772\/9335\/5062\/files\/GSM_SIM800L.jpg?v=1787646109","url":"https:\/\/tecwizdom.com\/products\/gsm-sim800l","provider":"Tecwizdom.com","version":"1.0","type":"link"}
