Multi-functional Integration: Based on SIM800L module, it supports quad-band network(850/900/1800/1900MHz), which can be used for sending a message, making a call, transfer data through GPRS to meet various IoT requirements. You don't need to buy multiple devices to save cost and simplify system integration

Easy to Develop: Integrated TTL serial port, can be connected to the microcontroller through UART, supports command including 3GPP TS 27.007, 27.005 and SIMCOM enhanced AT commands

Easy to Use: Onboard self-ejecting card slot, with just a gentle press, the slot automatically releases your SIM card without the need for external tools like eject pins or tweezers

Low Power Consumption: Adopting advanced low power consumption technology, suitable for devices that need to run for a long time. Reducing energy consumption reduces the operating cost of the device, and the low-power design makes the device more suitable for outdoor or mobile scenarios, without the need for frequent charging or battery replacement

Widely Application: Applicable to the Internet of Things, remote control, location tracking and alarm systems and other scenarios, to meet the needs of different industries, to provide flexible solutions
