Hello there,

so my cheap electric herb vaporizer from Aliexpress stopped charging so that when I turned it on, it immediately after few seconds started blinking that it isn't charged. So I opened it up and replaced old lithium battery cell with new fully charged battery and it still does the same thing. So battery wasn't the problem.

Nevermind what the actual problem is, I care more about chip that was used for this vaporizer and if I could reprogram it through its USB port. When I connect it to computer it connects, but doesn't recognize device. Only label on this board that I found was PPP-v72 and didn't found much information on internet.

My file of 10 MB is too big for this site so I uploaded pictures of board through uploadfiles in zip :D so here is the link(expires after 30 days) if you wanted to see the board itself: https://ufile.io/xznjbmwp

I would love to learn more about this chip so thank you for any information.

Hello,

Shrink the file to about 300K and post it over here.

Hello,

I can not read anything on the chips.
I have downloaded the large pictures, but also the text is unreadable.
Can you make sharp close-up pictures of each chip (I see 3 chips)?
