SIM800L GPRS GSM Module with Antenna

The SIM800L GPRS GSM Module is a compact cellular board that connects your project to 2G mobile networks using a Micro SIM card. The gprs sim800l module communicates over UART (a two-wire serial connection) using AT commands (short text instructions) to send SMS, make calls, and open GPRS (mobile internet) data connections. It covers quad-band GSM at 850, 900, 1800, and 1900 MHz, making it compatible with Indian networks. The module runs on 3.7V to 4.2V DC, which is exactly the range of a standard 18650 lithium cell — making battery-powered builds straightforward.

A detail the sim800l gsm module datasheet highlights is the GPRS multi-slot class 12 standard. this module can use up to four time slots for downloading and up to four for uploading simultaneously, giving better data throughput than lower class GPRS modules. The honest trade-off is the power draw on connection. When the SIM800L first registers on the network, the current spike can reach 2A for milliseconds. A microcontroller USB pin cannot supply this. You need a dedicated LiPo or lithium supply with at least 500mA continuous capability, with a 100µF capacitor across the power pins to absorb the spike.

The sim800l gsm module works with Arduino IDE and PlatformIO using standard serial libraries. Students learning mobile communication, makers building SMS alert devices, and engineers prototyping IoT nodes use this board. Connect UART TX and RX to your microcontroller, power from a lithium cell, and send AT over serial monitor at 9600 bps to start. StemVolt offers fast and reliable delivery of this module across India with trusted service support.
