Love these Lilygo modules. I used the TTGO-TCALL exctensively for one of the agritech project.

BenCos18•3/14/24, 4:08 PM

Yep lillygo stuff is nice for sure

Navadeep•3/14/24, 4:08 PM

They're probably the first to find innovative combination of modules to build a devkit around it.

@Saii Welcome! Can you let us know a bit about your technical background, what brings you to DevHeads, and what you're looking to learn/contribute?!

Good evening guys ,
I have a PCB inside a waterproof box outdoors, and it's happened twice in a few months that I've had a short circuit because of metal filings.

Do you have any recommendations or solutions to isolate my board, add protection??

kristof-at-embeetle•3/14/24, 7:39 PM

JLCPCB has an option to cover your PCB in a protective coating

kristof-at-embeetle•3/14/24, 7:39 PM

I never did it, but I think it's some kind of epoxy

Kkristof-at-embeetle I never did it, but I think it's some kind of epoxy

Albaphet soup•3/14/24, 8:53 PM

Like as a solder mask? Or everythings epoxied down

kristof-at-embeetle•3/14/24, 8:54 PM

An epoxy liquid is poured on the assembled PCB

kristof-at-embeetle•3/14/24, 8:54 PM

Then solidifies

aymen ammari•3/14/24, 9:07 PM

I've worked with tcs34725 before it give good results but it can be effected a lot with day light or indoor light, and you have to reprogram your MCU, so... I don't recommend it, I haven't worked with the other you can try it

Camila_99$$•3/14/24, 9:19 PM

aymen ammari•3/14/24, 9:40 PM

You can cover it with resin epoxy it's more affordable, you just mix it and pour it in the box, don't worry anymore about over heating or short cercuit, yes you won't be able to see or work on it but it will work out, tell me what you think

Hi guys, i was looking for a device based on ESP32, that can do Chat, File transfer, Voice and Video call between ESP to ESP only. Is it feasible or do i have to look at other MCUs?
