How do I know which version pi I have?

Thu Mar 22, 2018 4:09 am

This seems like a simple question, but- I have an old pi- say, maybe 2 or 3 years ago. And I'm trying to figure out which version it is.

Well- mainly what I want to know is how big of an SD card can I put in it? It takes regular sized SD cards so that shows that it's old, but yea, what size is max?

So here's what I dug around in:

Talks only about the most recent ones, so not useful to me:
https://www.raspberrypi.org/learning/ha ... pberry-pi/

So then:
https://www.raspberrypi.org/documentati ... /README.md

If this is somehow telling me what size SD card I can take.... I'm underqualified after 19 years of software developlent to know:
https://www.raspberrypi.org/documentati ... matics.pdf

So then I tried this:

https://www.raspberrypi.org/downloads/

Well, no of course that's not it either. (but that's to be expected, that's ok.)

So then..... how do I find this out?

And I'm not talking about by the date I bought it, I mean both by the physical motherboard and then within that where do I go on the site to get the SD question answered?

There are some older models not covered in that link. If you have a Pi Zero with no camera port, then it's the original Pi Zero, if you only have 2 USB ports and a 26 pin GPIO header, it's an old model-B. If you only have 1 USB port and a 26 pin GPIO header, it's an old model-A.

If you still can't figure it out, post some pictures of your Pi.

As far as SD card capacity goes, it should work with just about anything available today. I believe there was something on the site that said they had tested up to 128GB. Since they work with 128GB card, they are compatible with SDXC that can go up to 2TB capacity. In theory, anyway, since there are none that large yet (if you see a 2TB SD card for sale, it's fake).
My mind is like a browser. 27 tabs are open, 9 aren't responding,
lots of pop-ups, and where is that annoying music coming from?

Model data is silk screened onto the top of the PCB by the headers in a human readable format. It is in the general format of "Raspberry Pi N Model X Vy.z", where 'N' is the generalion, 'X' is the series, and 'y.z' is the board version number. On the Pi Zero series, it's on the bottom of the PCB.

Two examples...
Raspberry Pi 2 Model B V1.1
Raspberry Pi 3 Model B V1.2

this command show the version of your pi

Code: Select all

sudo cat /sys/firmware/devicetree/base/model;echo

Fixed.

(You don't need sudo to run that cat command.)

Micro SD cards were used starting with the Pi B+ in 2014. Thus, you probably have the original Raspberry Pi B. The question remains whether it is a revision 1 or 2 board, how much RAM memory it has and, of course, your original question about which capacity SD cards are expected to work. Sorry I can't definitively answer that last question. Maybe any card will work.

Any should work, up to 2TB. Since the biggest SD card that actually exists, is 1TB (and seriously expensive), that means any SD card you find today will work on a Pi of any model, correct size prevailing (micro or full or micro / mini with adaptor to full)

Of course, that doesn't mean you won't find fakes, but even they should work. Just don't expect them to be the 1YB they claim.
