SIM800L V2.0 5V Wireless GSM GPRS Module with Antenna

SIM800L V2.0 5V Wireless GSM GPRS Module with Antenna is an upgraded quad-band GSM/GPRS cellular communication board engineered with an onboard 5V-to-4V high-current step-down power circuit, allowing it to be powered directly from standard 5V DC supplies without external level converters. Centered around the SIMCom SIM800L cellular engine, it enables microcontrollers like Arduino, STM32, and ESP32 to make voice calls, transmit SMS text messages, and establish TCP/IP cellular internet connections.

Key Features:

• Direct 5V Power Supply Compatibility: Onboard low-dropout voltage regulator accommodates direct 5.0V DC inputs with high pulse-current delivery.
• Quad-Band Worldwide Cellular: Operates across 850/900/1800/1900 MHz global 2G GSM cellular frequencies.
• Full Communication Suite: Supports voice calls, bidirectional SMS messaging, and GPRS multi-slot class 12 data packet exchange.
• Micro SIM Card Push-Pull Socket: High-reliability spring-loaded micro SIM card slot located on the underside.
• Dual Antenna Connectivity: Features both an onboard IPEX micro connector and an included high-gain helical rod antenna.
• Hardware Ring & Network Status LEDs: Visual indicators provide real-time feedback on cellular search, registration, and incoming calls.
