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.

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

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

You can utilize ESP32's Wi-Fi features along with suitable protocols like MQTT for messaging and WebRTC for voice and video calls

well done! How long did it take to get provisioned?

Its 5.1v i measured it so its not a power issue i think
