It works with Arduino Uno\/Mega (with 5V tolerance), ESP32, and Raspberry Pi (level-shift required). Requires a stable 4V supply capable of 2A peaks; we recommend a dedicated Li-Po battery or a 3.7V–4.2V buck converter. Pair with a GPS module like NEO-6M for live tracking.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eConnect VCC to a 3.7–4.2V power source (not to Arduino 5V), GND to common ground, TX to RX of microcontroller, RX to TX. Use a 1kΩ resistor on RX for 5V micros. Ensure antenna is connected before powering.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.\u003c\/p\u003e\n\n\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino Uno?\u003c\/summary\u003e\u003cp\u003eYes, the SIM800L can communicate with Arduino Uno using Serial (SoftwareSerial). Make sure to power the module with a separate 3.7–4.2V supply as the Arduino 5V cannot provide the required peak current.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eDoes it support 4G\/LTE networks?\u003c\/summary\u003e\u003cp\u003eNo, the SIM800L only supports 2G GSM\/GPRS networks. For 4G, consider SIM7600 modules.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eWhat SIM card does it use?\u003c\/summary\u003e\u003cp\u003eIt uses a standard Micro SIM. Ensure the SIM is unlocked and has active SMS and data plan. 2G network must be available in your area.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
