The NTAG I2C Test Card is now available

In a recent thread, I suggested that somebody get themselves an I2C Test card to test access on a door, to see if it is compatiable with an xSIID.

That, is one use for this card


I don’t currently have one, however, I am thinking of getting one.

Has anybody made “A THING” with one?

Practical or Not…But maybe just a little more practical than lighting up some LEDs

Here’s a good example

Also a couple of padlocks I reviewed used the I2C power harvesting to unlock ( Quite clever yet basic really )

Data sheet For reference if someone stumbles on this thread and wants some more info
