The PCBs from www.PCBWay.com... are almost ready, but not quite here yet, so I'm getting on with some other projects!
I've got way too many USB-C powered devices - and I've only got one USB-C cable coming onto my bench with enough power for them. It's time to fix that!
The ATX power adaptor I showed is this one: s.click.aliexp...
And the nice little USB step down board I'm using is this one: s.click.aliexp...
The Miniware electronic load can be got here: s.click.aliexp...
And the USB tester is this one: s.click.aliexp...

Had a look through lots of your videos over the last few days and recently subscribed. Thanks for sharing your knowledge 😀 I would appreciate a review of some of the tools you use, such as the FNB58 USB Tester, the battery tester (with the big fan), and the hotplate - I couldn't find any in your list, though I might not have searched too well !!

Can't wait to see your ESP32 PCB. Also, it would be cheaper to buy 4 single channel modules at $2.63 each, than to buy a 4 channel board for $20.38 !!! Who prices these?

@atomic14 11 месяцев назад

I’m looking forward to it as well! Pricing on AliExpress is one of those unexplained mysteries of the world…

Where can I find this usb tester?

@atomic14 11 месяцев назад

You can get it here: s.click.aliexpress.com/e/_DDEF6En (affiliate link) - but shop around for the best price... There's also newer versions the FNB58!

Nice showcase for the usefullness of these qc charger modules and miniware load. I have been using a earlier version of these (QC 3.0 module) probably the same as @lezbriddon mentioned. They were being used on a 24V solar project and i found they get especially hot when charging devices like power banks. You may want to soak test the board with a load for a longer period of time before designing a case as free air flow may be required or the addition of the self adhesive little heatsinks put on rasberry pi's.

@Harry-nd8xd 11 месяцев назад

After re watching some of the video it looks like it's not possible to add a heatsink for this version of the board as components are loaded on both sides.

@atomic14 11 месяцев назад

Good idea. With all the devices I've got I can do a good load test and see how it looks with the IR camera. Just charged up a power bank and the board got warm to the touch - and that was just running at 9V so not even pushing things.

@Harry-nd8xd 11 месяцев назад

Nice, will be interesting to see how the testing goes. 👍

@lezbriddon 11 месяцев назад

just bought one last week for more sockets in the van, but its not the same, I have surface mount inductors(220) and only half as many capacitors, so i'm guessing your boards design may be the better performer as I'd edge my bets the IC is the same (id removed by laser...) (pin2 inductor 5&6 d+/d-)

@atomic14 11 месяцев назад

I've put some close up shots here: open.substack.com/pub/atomic14/p/i-need-more-usb-power the IC on my board is an SW3518

I don't understand why the push for all things USB powered. Great for working in the field, but at the bench why? I have power on the bench up to 45v and up to 30A with all the voltage and current limits you need, and USB ports for data. So you are making a mains power supply to power USB devices? seems that the world is going around in circles. As a side note my soldering irons are all mains except for one gas powered one for use away from mains. The only reason i can see for going the USB route is they don't need to supply a power supply. which due to the questionable safety of a lot of USB power supplies is a good idea for them.

USB-C tools tend to use a lot less space on the table.

@TheEmbeddedHobbyist 11 месяцев назад

@@ArtiZirk That may be so, but I'll take functionality over space any day. Plus I like the protection that a lab power supply provides. it my working on circuit takes 100mA max I can set the current limit so that if there is an issue the circuit has a better chance of survival. Also my current soldering iron is smaller than all the current USB ones and is mains powered. the power station is just away from my work area. Check out the size of a Weller WXMP.

@piconano 11 месяцев назад

This is why I don't own anything USB powered on my bench. If I need portable power, there is my trusty $250 Bluetti EB3A. But being a nerd, I have thought many times of buying a USB soldering iron to go along with my cordless drivers, and had to talk myself out of it. 🤪

@atomic14 11 месяцев назад

I think your last sentence sums it up - pretty much everyone now has some kind of high power USB-C supply - either for their phone or their laptop. So all the manufactures need to do is include a decent cable.

@ArtiZirk 11 месяцев назад

@@TheEmbeddedHobbyist that's true, real lab equipment will be miles better than any USB-C based tool. We have few Weller soldering stations at my day job R&D lab and they are a lot nicer to use than the Pine64 Pinecil I have at home.
