KI had modified the code, I mean I changed the SDA and RST PINs allocation
KYes I did!
NPlease note which pin in NodeMCU is SS. It should either be 15 or 11 based on which SPI instance you call on your code.
NTry SS pin as 11 for the SPI you're using.
KSERIAL monitor not working with NODEMCU
K"It leads to a different root."
NIn the serial monitor, pick 'NL and CR' mode from the selection below. This will get those junk characters out.
PI think we should, please, start discussing topics in the relevant channels to keep it clean
NOkay. True, that makes sense. Taking this over a thread now.
N@Phoenix do we have a way to move these conversations to a thread now?
KThe Tiny Scarab board is ready:

KI'm going to do a small scale test production at Eurocircuits. Please let me know if you're interested in one of the prototypes.
TCongrats!
The server is happy to support the production of additional prototypes. Are you willing to make as many as people who want one, Kristof?

Plovely board, congrats @kmulier !
Flooks cool but eh looks super technical too. idk if i would be able to program it
TThere’s another coming based on RP2040 i believe. Our plan is to create demos and tutorials on top of these over time.
Fthat would be nice
T@K.L.NAGARAJU yeah we can move it under #mcu-mpu-and-kits . I’ll tag you.
T@Phoenix, target thread channel ID not being identified (1196129943084613753). Need assistance moving images. After resolved I can migrate the rest of the conversation.
KI can put the DevHeads logo on the board, along with an URL
KWhich URL should I put there?
TKThanks Brandon
TThank you!

KHi guys,
Please have a look at the Tiny Scarab board design:
https://github.com/Embeetle/tiny-scarab/tree/main
I've wrapped up the board design and I'm now looking into the fabrication process. Eurocircuits is an option, but it's rather expensive. Please feel free to share your experiences with other board fabs.
As for the production files, please scroll down on the main GitHub README page:

I suppose my question would be is it a dev board a la Arduino Uno, or is it a sort of GPIO pass-through that you control via your computer? Or is it something else? Maybe a TL:DR summary of what is it exactly? Nice looking board though, as are the docs aesthetics-wise.

KHi @JeremyCook ,
It's a development board for the
The board has an on-board flash/debug probe which you connect to the computer with a USB-C cable.
I'll rewrite that part in the documentation to make this clearer

TThanks y’all. We are now over 150 LI followers and have applied for streaming privileges so Office Hours and other segments will now be opened up to the world - pending LI approval, of course
TThis is very easy to read. Thanks!
My first question is what does this mean:
“The Beetle Boards will get special attention in Embeetle IDE.”

TMy next comment is that @Petr Dvořák and @pallavaggarwal may have a decent handle on board gave depending where you’re looking to have it manufactured.
@pallavaggarwal, @Umesh Lokhande, what did Altium do to the Gumstix brand? Is there still a low volume quick manufacturing option through them in the west?

TWhat is the cost at Eurocircuits? Have you considered a kickstarter?
P@techielew Because of the Chinese chips, I would consider JLCPCB or similar companies. Everything else probably brings more headaches and higher cost.
PAnother plus is that JLCPCB offers 3D printing and CNC machining. @kmulier can design an enclosure or some kind of accessories easy to order there.
T@Padmalaya Rawal would you be interested in supporting/collaborating in this regard? See above.
TIs Alibaba the only WCH distributor at this time?
PI would love to contribute @techielew .
@kmulier As your board is open source, you can apply for OSHWA certification which is free. And then you can ask people at OSH Park for your initial PCB fabrication. And if you are considering to produce them in bulk I think it will be better option to ask JLC or PCBWay for the sponsorship. They will reduce their prices in the exchange of their name to be there on prmotional material and github. I hope it helps

KThank you guys.
Yes, Alibaba is now the only distributor for WCH outside China.
Thanks for the tips. So right now, the options for a prototype production are:

UHi, @scitechindian welcome to the community!
P@kmulier Be aware, those sponsorships can backfire easily.
