Module model: SIM800L Working voltage: 3.7~4.2V(current peak 1A, please do a good job) Support network: global quad-band network Module size: 2.5cmx2.3cm The serial port is TTL serial port, which can be directly linked with the MCU. The module is powered on and automatically starts and searches the network On-board signal indicator (blinking slowly if there is a signal, blinking quickly if there is no signal) Small size, there is no GSM module smaller than this module Full machine SMT processing, reflow welding, stable performance factory direct sales Power supply can be directly powered by lithium batteries, as shown below:

The line layout is compact and regular, with good electrical insulation and mechanical stability, and can maintain stable performance under different temperature and humidity environments to ensure accuracy and reliability.

In circuit design, carefully planned lines are like precision transportation networks, and lines of different widths and spacings undertake different currents and signals transmission tasks respectively. The key signal lines are impedance matching processing, which greatly reduces signal reflection and attenuation and ensures the stable transmission of high-frequency signals.

All kinds of electronic components are soldered on the circuit board, and the solder joints are full, round, and firm and reliable. Core components like chips are perfectly connected to the circuit board through fine packaging processes to achieve high-speed data processing and interaction.

This circuit board has a wide range of responses in many fields. Whether in the industrial control field that requires extremely high stability or consumer electronics field that pursues extreme performance, it can provide solid guarantees for the stable operation of the equipment with its excellent design and reliable performance, and help various electronic devices play a powerful role.
