I do like the 3D case make from the #KiCad #PCB files so fits perfectly...

OK, I have been tinkering again. I quite like this board - it is designed to take 12V DC, and drive 10 separate outputs at 12V DC. Intended for the alarm system, but works for lots of other use cases (e.g. nice big 12V LED lamps in my DEFCON light box).

My latest tinkering, apart from ESP32-S3, is to put a WS2812 by each output plug to allow output status to be shown clearly.

I might order some when back from my holiday.

I have updated the details on #Faikin PCBs #Daikin #PCB

I've not played with these tiny 1mm x 1mm WS2812 LEDs before. They really are tiny. #PCB

Fun latest board...

#ESP32 #PCB

Well, that is one of my simpler programming leads 🙂

Oooh, I like my new test board, especially as the USB JTAG/Serial is working as expected now - reset and flashing just work. Way better. #ESP32 #PCB

JLCPCB finally have the 3D model for the S3. #PCB #ESP32

I think I can make a couple of mm shorter and still keep it single sided. Fun. #PCB

[Yes temp sensor next to processor = bad, I know, it is a test board, and probably fine for humidity]

What the hell is wrong with #jlcpcb

I sent U2 as rotation 90.0 degrees.

This has always been with antenna on the left. Another order on the same day with the same part at 90.0 degrees shows antenna left.

Yet this order they consider 90.0 degrees to be facing up, and "corrected" it to be facing down.

Arrrg!

(Yes I had silk screen to show the orientation, and they edited it out FFS). #PCB

So I am a couple of days in to "The S3 ESP32 is the next thing" without having one to play with. Order some boards. Tinkered with foot print a bit. Made some other designs to use it. Read up on usable GPIOs. By the time I have actual boards next week I'll have re-done most of my PCB designs. I really hope I am not disappointed. #ESP32 #PCB

This may be more useful to start with. #PCB #ESP32

OK, let's see if I can make one of these work... #PCB #ESP32

Guess which way up this should be...

Arrrg!

#PCB #JLCPCB #ESP32

I tried.

I put a mark for pin 1
I sent the right positions file
The GDN pad has a chamfer for pin 1

WHY ME?!

Looks a bit like the starship Enterprise, but seems to work. #ESP32 #PCB

"GPS":8,"Galileo":2,"GLONASS":7

Liking the #PCB "tear drop" feature. #KiCad

For my next trick, trying to make up the panel for a #JLCPCB #PCB order myself. Only snag is V-cuts as I can't work out what file they expect for them, so I'll add notes.

But the end result is I should need a lot less labelling on these when sending to Amazon. Just need to find reasonably clear anti-static bags now.

I have a load of spare bare PCBs. Most work, and most have date codes so the exact schematic can be found on my github if you try. It seems a shame to chuck them out. Is there anywhere that would be a good home? Maybe a #hackspace that just wants to practice soldering, or actually use some of the boards. A good example is those purple ones - very few components needed to make a USB powered #ESP32 board. Just that actually ordering more boards was/is sometimes cheaper than fewer! #PCB

Busy morning, trying a new regulator (MD8942), synchronous, and somewhat cheaper than the LMR16006. 4V-36V in is a nice range. I'll see how well it works when the #PCB comes next week. Side by side comparison on oscilloscope...

A tantalum output cap may be overkill though.

The CH340X is physically about the same size, but simpler pin out than FT231XQ.
