There is no serial number in accelerometers, you can only read out which chip is inside by reading the register WHO_AM_I.
Does it answer your question?

I suspected that was the answer, but I had said a short pray to the Norse gods. I am using MKI210 using a MKI109V3. It would be a nice feature as the accelerometers get put in specific places and tied to a SQL page, a unique number is nice.
Do you have an equivalent to the 109 with ethernet support, we want the acclerometers at a distance.

Smiling to oneself, I had to write the software to read your 109 in a useful format. Your manuals assume a high skill set. The UNICO GUI Lite is a challenge. There is a long step from your board to this graph.
What is a discovery board?

The STM32F401VE on the MKI109V3 would have a UNIQUE ID code
Ethernet boards using an STM32 would have that, and presumably a MAC address
Perhaps one could port the MKI109V3 like design to an F407 and add Ethernet, or find a chip/board level Ethernet + PHY + SOCKET all-in-one type solution.

Discovery (DISCO) boards are relatively cheap evaluation boards.

This for example has Ethernet + POE + Arduino Shield connector, perhaps more bulky and costly than desirable.
Some of the NUCLEO-144 boards would be cheaper, and are more of a breakout board, with relative little in bolted-on functionality.

If you could fabricate a simple accelerometer shield, these might be the way to go.

Can I connect the 109 accelerometer directly to the discovery board? We are replacing 2400 USD devices, the cost is not high.
The people I am working with, were smiling at the elastic hair bands I needed to use to hold the little connector from the 109 to the 210. Do you have a clip to hold them in place?

The MKI109V3 isn't my circus, not sure if you can update the firmware, or what functionality you're using.
If I wanted to map it onto some cheap Ethernet platform, I'd probably see if the USB and a RPi would be the way to go.
For a NUCLEO or DISCO, would probably look if I can get the BlueTooth pin headers mapped to USARTs on the host board. Perhaps fab a simple shield routing pins, and mapping to the headers such that it would plug in, and screw down.

Hi @Macneacail ,
you might read the 2D code (with a 2D code reader) on top of the ISM330DHCX if you are using a STEVAL-MKI210V2K.
In this way you have a 1-1 traceability of the device.
