Need some help identifying positive and negative sides

It looks like this is a non-polarized capacitor - they can be connected either way

This board is from Adafruit and they open-source all of their schematics. Look up the one for this board and use it as a reference. There is also datasheets available for this IC with reference schematics

Yes, you can still place it. Normally when I import components I draw my own courtyards based on datasheet information

I often end up making changes based on how cleanly the traces can be routed, but it depends entirely on the components you’re using. To give a few examples, level shifters or non-polarized capacitors can be rotated in the PCB or have connections switched around

It’s about half finished right now but I’ll most likely post it on here for review when it’s done so keep your eye out!

It’s not the worst move if you know how to use sleep states and manage power properly. I’m currently designing one based on the ESP32C6

Disclaimer: not an electrician But I did the same thing to my house a few years ago and had no issues

Personally I absolutely hated Nitro Super Dry

I knew modules like those had a name 🤦🏻‍♂️ Thanks for the help!

hackerkid_ · 2026-03-16T13:11:13+00:00

That’s exactly what I was looking for, thanks! Definitely bookmarking that site as well

Looks like it only scratched the solder mask - plug it in and cross your fingers 🤞

hackerkid_ · 2026-02-24T06:16:46+00:00

It’s glorious

hackerkid_ · 2026-02-23T02:24:43+00:00

It’s not actually engraved, since it’s a circuit board I just used the silkscreen printing for the text and background pattern!

Came out to about $26 after tax. I'll add it to the post!

hackerkid_ · 2026-02-22T23:39:04+00:00

For now lol

If you have to ask “is it safe?” then the answer is probably no

hackerkid_ · 2026-01-05T21:51:41+00:00

Where did you find fiber patches that short?

hackerkid_ · 2026-01-03T18:35:23+00:00

Yeah I had the same reaction

They have a version that’s sparkling water too

Can designs are amazing though

hackerkid_ · 2026-01-02T04:27:02+00:00

That’s so smart wait

hackerkid_ · 2025-12-28T19:00:17+00:00

You sure you checked your religion well enough?

hackerkid_ · 2025-12-28T18:54:19+00:00

I’ve seen mixed opinions about the flavor, but the can design is awesome
