Back in March I wrote about some simple experimenting with the ST M24LR Discovery kit which feature a dual interface EEPROM - both NFC and I2C. That kit got me thinking about how I might use NFC to move data to and from low cost devices. Not just storing data on a tag, but mini data loggers and the like. So I ordered a few parts to experiment with and yesterday I finally got around to building some I2C/NFC tags. Here's one -
There was no particular project in mind when I assembled the parts, which is why I included the 0.1" pitch connectors to plug them into a breadboard. What I notice once they were on the desk it that it's an ideal size to include in a Raspberry Pi case. So I built another slightly different one.
As for the Raspberry Pi interface, what I'd like to do with that is use it to change settings that are loaded on rebooting - so I can set up Wifi access codes using a phone or tablet, ideal for a "headless Pi".
