Multi-functional Integration: Based on SIM800L module, it supports quad-band network, which can be used for GPRS communication, SMS sending and receiving to meet various IoT requirements. No need to buy multiple devices to save cost and simplify system integration

Easy to Develop: Integrated TTL serial port, can be directly connected to microcontroller; provides rich interfaces (UART, GPIO), can be connected to the main device through UART, insert SIM card and connect the antenna, use AT commands to configure the module to achieve the communication function

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

Signal Indicator: On-board signal indicator, it flashes slowly when signal is present, flashes quickly when there is no signal
