Using Silicon Labs LTE-M Expansion Board

Do you have sensors out in the middle of nowhere? Are they in an empty field? How about in a building that you have no access to the Wi-Fi? You need some way to get that sensor data. Well the easiest way to get it is to send your data over a cellular network. But you don’t need any of those fancy 4G data plans with unlimited data. No, what you are looking at is something known as LTE-M. It is a lower data intensive bandwidth meant for IoT. I have a project using Silicon Labs’ expansion board for LTE-M. You can read more about it here. It is a simple project showing how to get connected to a network and sending data easily.

Ben Roloff, Associate Applications Engineer at Digi-Key Electronics, has been helping customers with all their microcontroller needs since 2016. He was born in 1991, a time when internet was unheard of in the home. Internet slowly became a thing as he went through school - so in a way, Ben grew up with the internet. It was his interest in computers that drove him to pursue an education in computer engineering and he holds a Bachelor of Science in Computer Engineering from the South Dakota School of Mines and Technology.
