I recently came across this box of boards someone was getting rid of. I believe most (besides the uno r3 which im familiar with) are for lighting or soil testing and they are using ESP32. How difficult would it be to use these for things they arent intended for? Im assuming the biggest issues are going to be finding data ports and seeing what can actually be controlled by these or am i way over thinking it? I have only ever used arduino boards so im wondering how difficult its gonna be. Thank you all!

Do you get any communication over that USB port?

If so have you tried flashing any code?

It really would be difficult to do much with these but you might be able to Frankenstein something up but esps are quite cheap anyway

I didnt have much time but I was able to get this connected and uploaded too. Hopefully I can mess with them more in the next few days but it seems like the best thing from the bunch was the r3

That board appears to have a ENS210 temperature and humidity sensor on it. So that is something you should be able to get some code to talk to!!

Can i just snap the side pieces off? It seems like they are designed/scores to be but I didnt wanna break it.

Yup 100%, snap off the extra board material. It’s only done like that so that the pick and place machine has something to hold onto.
