I think I may be better off making cardboard models or put energy into
a white board for the short term. A daughter board for a 100 pin device
that needs to solder in place with .1" headers involves
geometry/mechanical skills where my execution speed is off by orders of
magnitude.

Don't need help, thanks. The v0.01 board will be what it will be. Was
flirting with dropping out of the fun zone but recovered. :-)

Thanks again, Josh. I appreciate it. Got to go with the Adafruit
huzzah lib 'cause of time. Actually, I'm in trouble and need
somebody(s) good with Eagle to swing by and help if possible. I was
expecting OSH Park to say I could get it to them tomorrow. Another
mistake.

Negative on the eagle, I apologize.
But I found these:

Sorry for the confusion. Do you have an Eagle lib for this? Have
to upload to OSH Park by 6pm.
THANKS!

The link I shared was for ESP32 boards. What I was trying to
convey (and maybe was miscommunicated, yay email!) is that
these linked ESP32 boards seem to follow a form factor and
convention of prior/historical ESP8266 boards, and therefore
bring some additional consistency. I attached a screenshot of
the page that loads for me, from that Amazon link.
Thanks,
Josh

Thanks very much, Josh. Agree with point about pin
conflicts. But did i go to the wrong page? I want to use an
esp32 not 8266. This is for the "0.01" versuon of the
community project board.
Nov 15, 2021 1:11:29 PM Josh Wyatt <[email protected]>:
This is sort of an indirect response to your question,
but my experience is that the more complex and
"featured" the dev board, the less consistent. For
example, for boards with onboard 18650 battery holders
and Liion charger, OLED display, and even onboard LEDs
will be on different I/O ports. So my guidance would be
to choose the simplest boards available, which is sort
of antithetical to the "dev board" concept.
I've had pretty good luck with consistency on the
"wemos esp8266 clone" boards, presumably because
the Wemos D1 mini became very established with the
8266; search on amazon for "esp32 d1 mini." Here's a
link:
https://www.amazon.com/Bluetooth-Internet-Development-Functional-Ardu-ino/dp/B08MFCC4SR/?th=1
You mentioned soldering footprint, and that one's not
super friendly; but it should be pretty consistent
since the design tries to adhere to the original
ESP8266 Wemos D1 Mini form factor.
You mentioned Amazon specifically, so I assume you're
prototyping?
Thanks,
Josh

What esp32 dev board soldering footprint should be
used on a board combining this with other stuff
where it has to be 1) obtainable reliably 2) offer
wifi and BT and 3) be cheap? I see many cheap on
amazon. Are their pinouts de facto standard? And
finally, anybody got an Eagle lib for this board?
Or could you make and send me an .lbr for it?
Thanks in advance.
