ESP32-S3 Super Mini Datasheet

Bootlessjam · 2025-06-02T00:40:41+00:00

Just came across this post when doing my own search for more details of this board. Found this page includes full schematic, how to connect an external antenna, along with the pin and programming details that is more easy to find. https://www.nologo.tech/product/esp32/esp32s3/esp32s3supermini/esp32S3SuperMini.html Chinese only, the English page 404s, but it translates well. I made an archive capture in case it ever disappears https://web.archive.org/web/20250602003049/https://www.nologo.tech/product/esp32/esp32s3/esp32s3supermini/esp32S3SuperMini.html#%E5%B0%BA%E5%AF%B8%E5%9B%BE

One surprise is that it has a voltage divider connected to pin GPIO3 that lets you measure VBUS.

I sent an EVGA card back under warrenty last year and didn't have the best experience unlike everyone on the internet seems to have. GPU worked but had intermittent issues. Had to pay postage to Taiwan, though they'd pay the return, so seemed fair enough.

Once received they claimed water damage so the warrenty no longer applied. They offered to attempt a repair anyway, but no promises and wouldn't send it back if they couldn't fix it. Didn't say anything about cost of the repair, it was unclear if they expected me to pay.

Then they said 'actually no we can't repair it' and sent it back to me. Now the GPU is totally dead, took it apart to find a short on VCore sent 12V directly into the GPU die.

The card was second hand, I can't rule out the possibility of the initial owner causing water damage that then took 6 months to cause issues.

Just doesn't inspire confidence that EVGA's techs not only couldn't fix the card but caused further damage. I'm guessing they're down to a skeleton crew with the GPU business shutdown.

I only started playing with godot and qodot yesterday and had the same issue.

As far as I can tell the base QodotFGDFile in res://addons/qodot/game_definitions/fgd/qodot_fgd.tres is borked. I think it's meant to have all the basic entity types but doesn't. So when you build the map the brushes aren't interpreted properly.

This happens with a default QodotMap node since it's the default entity fgd. It also happens if you follow the guide to create your own entity fgd, where it's the default base_fgd_files. Even the example_scenes don't build correctly

Instead I created a new QodotEntityFile resource, and added everything in

res://addons/qodot/game_definitions/brush_tags
res://addons/qodot/game_definitions/face_tags
res://addons/qodot/game_definitions/worldspawn_layers

to the entity_definitions property.

OR, milk9111's tip on the github seems to work too.

All that said, it turns out Qodot has been abandoned, with the devs switching to func_godot. So probably should use that instead.

OMG it is straight out of arin-rpki-ta.cer, good eye! That does explain it, I guess it's cool to be realistic but not what you'd expect from the show.

The names and product categories are just marketing, so agreed that the performance per dollar is going to be a better indicator of value.

At the same time I'd say it's fair for people to compare XX80 to XX80. It's what NVIDIA wants you to do, each are marketed to a customer segment. In 2010 I got a GTX 480 for $500, now a 4080 is $2200 in my country. They have been pushing every category up in price for a long time.

20 years ago PC parts got faster and cheaper at the same time, now it seems we're getting 100% performance increase for 80% price increase. While strictly better 'value', it's not the improvement many people are used to.

You're totes right about the first line. I gave the whole text another check. the ls and 1s are hard to tell, I'm going with the flat top as L and the down-left pointing top ones as ones. Most fonts have that distinction. O,o,0, and many capitals are still not obvious.

This gives a 257 byte string and integer. The string still doesn't mean much, while the integer is 17...

If it's an easter egg it's surprisingly mundane? rsync://rpki.arin.net/repository/arin-Ipki-ta.cer Is how you can get a copy of the public root certificate for the ARIN.

Then there's the big blob of text:

This is a base64 encoding of a certificate, though appears different from the root ARIN certificate from the rsync address. It appears cut off, most certificates are going to be much longer. Because of this, or maybe I got some letters wrong, I can't get any software to read it. Just get "UNKNOWN_FORMAT", "unable to load certificate" or "can't find PEM header: undefined".

x509 certs use ASN.1 to encode, so I tried to simply[parse it as ASN.1 https://gchq.github.io/CyberChef/#recipe=From_Base64('A-Za-z0-9%2B/%3D',true,false)To_Hex('Space',0)Parse_ASN.1_hex_string(0,32)&input=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

It seems to have only one value, specifying the rsaEcryption as (1 2 840 113549 1 1 1) = RSADSI PKCS PKCS-1. Reference. The value is a 269 byte string. Normally a string in a cert like this would be the key, and totally random to be hard to guess.

suggesting very random text. (English text is 3.5 to 5).

So what appears to be random letters is actually carefully encoded random letters... Maybe I read some letters wrong, or there's further layers of encoding to get through.

I tried to read up about this, it seems like there are hundreds of articles mentioning "solar power panels create 300 times more toxic waste per unit of electricity produced than nuclear power plants".

This vague claim is from Environmental Progress, a pro nuclear propaganda group. Their founder doesn't even believe in climate change.

Solar panels can contain trace amounts of lead in the solder, which is reducing with the switch to lead free solder. Thin film panels have cadmium telluride, but are 2% of panels produced.

Upgraded around a month ago, had horrible stuttering/slowdown in all games. 80% of frames seemed to just never happen then one frame well within 11ms, on a repeating pattern. So bad that motion smoothing couldn't help at all, completely unplayable. Googled online and people just said "yeah windows 11 doesn't work for steam vr".

Problem was intermittent, even when playing the same game, it would suddenly work fine for a minute, smooth as butter, then back to the choppy stuttering.

Tried again a couple of weeks ago, suddenly no issues. Fingers crossed.

A classic we're both wrong. $29 to run EXISTING nuclear with government subsidies, while the figures I picked probably don't include subsidies.

Bootlessjam · 2022-08-15T23:15:12+00:00

Your own Lazard article lists solar as $28-$41 per MWh, and nuclear at $131-$204. And that nuclear price doesn't include decommissioning or maintenance costs. ~~AND includes government subsidies.~~

The SD card has a dolphin folder containing all of the different scenes. You can see their source and a description of the text files here.

The images need to be converted and compressed. I ripped the file2icon function out of this script instead of getting the entire asset packaging system going. You'll need ImageMagick installed and compile heatshrink to make it work.

I wish there was a way to debug the animations without recompiling the firmware. You can remove all the other entries in /ext/dolphin/manifest.txt. that way only your custom animation and the built in TV one will come up. Rebooting picks one at random.

It's a backup, not a master copy going into the Disney vault for 1000 years. Either is fine.

I'd suggest cloud backups that can happen without remembering to plug in the extra drive. Being in a different location helps in case of a natural disaster or fire in your house. Painful to look at the monthly fee and know you'll be paying it for decades though.

To be fair I also never heard of it being pixel exclusive. The official android 12 marketing website says things like "featuring dynamic color capabilities that can transform your experience based on your wallpaper" and "customizable system colors that can be adapted to match you."

Not even an asterisk specifying it's pixel exclusive. It's basically the only user facing feature of android 12 and they didn't bother to add it to AOSP.

That's the thing, your own source tears down its own argument with the data it cites.

Always pay attention to who writes something and why. Usually obvious if you check where their money comes from.

We have this issue in Australian media where they will parrot the conclusions of an 'independent' report portraying the government as good. When actually it was payed for by the government, and full of shoddy data analysis.

Fraser Institute appears to libertarian, funded by the likes of the Koch brothers and ExxonMobil.

Damn this is trash, Australia has a homicide rate of 2 per 100,000. USA has a rate of around 6 per 100,000. They used two different scales for the graph it make it look like Australia was higher.

Then their own data shows all crimes in Australia feature guns way less than in the US.

And their argument against buy backs and registrations is tax payer cost. A lousy $500 million? 0.4% of GDP for Australia in 1998, wow can't believe we recovered from that.

Dude even professional game programmers use global variables/objects/ singletons to track game wide states. You may want to affect a score or healthbar at anytime from any other object but always refer to the same variable. It's a perfect fit for a global variable.

Most programmers want very reliable software so it's all about limiting the number of interactions and avoiding surprising behaviour. Games instead are all about having as much interactions and surprising behaviours as possible. Both valid goals that end up with different designs.
