How can I tell which version electron is in my hands(2g - 3gUSA - 3G-Euro)?
I have several, and I’m trying to identify the 2g one.
Look on the cellular module for the model number. SARA-U260 is the 3G USA version. SARA-U270 is the 3G Euro and the SARA-G350 is the 2G version. https://docs.particle.io/datasheets/electron-datasheet/
