MCP3428, Boron and Feather microcontroller

Hi all,

I am using MCP3428 with Boron to get data from 4-20mA sensor and i use feather to IoT adapter, now i am looking for another microcontroller to replace the Boron, is there any other microcontroller that use Simcard so i can replace Boron?

i know i can use feather but which one that will fit on the adapter , also if there are more options that will be great.

your advice please.


Unfortunately there just aren’t many Cellular interface IoT modules on the market. It seems to be really concentrated on WiFi. The Boron and Electron are the only devices I am aware of that are readily available.
