what version printer is do I have?

I was given an Ender-3 printer by someone who knew nothing about it.
After some adjustments and installing a nozzle it seems to work ok.
I have some questions.
I notice this forum has sections for different versions of Ender-3. Which version do I have? Pictures attached. Which section applies to mine?

I downloaded “manual-ender-3d-printer.pdf” which I think is for my version. There are some things on my printer’s menus that aren’t covered in this manual. What does Store Memory and Load memory do? Is there a more complete manual?

Is there a way to see what version of firmware is installed? Are there updated versions of the firmware available for my printer? What I find on the Creality site refers to hardware version 4.2.2. The PC board in my printer has V1.1.3 on it. Is this the hardware version?

Thanks!

Hello @KitR …! :wave:

Welcome to the Creality Forum…! Creality

The only thing I know about yours is that it looks like you have one of the original Ender-3 machines that first came out in 2018 with an 8-bit board. V1.1.3

I would be cautious about downloading newer firmware if your machine is working good. :thinking:
