Due to a mistake by me the board was 0.1" to wide:
Got an offer for free PCBs to test and review PCBWay service for the new PCB so here is that with a redesigned board 0.1" smaller:
I sent the design to the one offering me the deal, but was told to create an account. Here is what I was getting when creating the account...
It complains about the password before I type it in. Pleases be patience computer.
Their page look nice.
I'm on the upload and setting page. All other cheap PCB manufacturer has the option to upload and auto fill the dimension and those stuff. That's something they are working on I was told.
Have to open KiCad again to check the dimension because they are not in my head.
Settings: Panels by PCBWay, black mate soldermask, 10 boards 27x58 mm
$42 probably the mate black. Would be good to mention what is extra and what is included in the base price. +$20 shipping is reasonable for 3-4 days shipping.
Got a mail asking for amount of boards and panel. Not really clear in their interface on this point. I believed that it was 10 panels. But in the end I got 10 boards on 5 panels, 2 on each panel.
Time to solder
PCBs from PCBWay and components bought from Digi-key.
Testing how easy they are to solder on here:
As seen there are more residue visible on the PCBWay board. It might be the matt black. The ease of soldering was about the same.
A scratch test:
About the same resistance to scratching.
Time to assemble.

Decided to go with the devkitC pinout but might change in the future if there is another board that seams more popular.
Included a 3.3V regulator that is optional if you use just a esp32-wroom module and need 3.3V
All files can be found in the Files section.
(going to add 3D model for missing parts in the final design :) )

A ruff idea on the layout and components. Have to find which devboard to use, but I have decided to use one of the nodeMCU like boards.
Next update will be a schematic and hopefully a decision on devboard.
(The 3.3V regulator is for the case where the devboard doens't have it on it)
