In this Article, I am going to introduce my New PCB Design, 4G LTE Module. We have made lots of cool projects using this 2G GSM Module Such as home automation, location tracking, sensor monitoring and remote sensing.
This 2G GSM Module is Awesome but this is era of 4G and 5G, 2G is outdated technology now. So Say goodbye to the limitations of the 2G GSM Module and welcome the future: The 4G LTE Development Board Design by technolab creation and manufactured by JLCPCB.
This 4G LTE Module is a versatile and powerful communication module that supports a wide range of wireless communication modes, including LTE-TDD, LTE-FDD, GSM, GPRS, and EDGE. It is based on the SIMCOM A7670C LTE modem.
Now we have a question, can this module Support JIO SIM-Card? The Ans is YES this module will Support JIO SIM Card.
And next best thing is that ,this module not only supports 4G Networks this module is also compatible with all 2G and 3G networks as well.
This is the Schematic of 4G LTE Module.
After making the Schematic, Convert it into PCB, Arrange and place all the components in desirable places, Once the layout is ready route the wiring and complete the design of PCB.
