Hi 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've tried to make the main page as clear as possible, with a nice overview and indexation. Please let me know if you find the documentation sufficiently clear.

JeremyCook•1/15/24, 9:51 PM

"There's no need to wire up anything. Just plug the Tiny Scarab in your computer and start coding!"

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.

kristof-at-embeetleOP•1/15/24, 9:56 PM

Hi @JeremyCook ,
It's a development board for the microcontroller. That means you can write code in any IDE and flash it to the chip (although we hope you will use Embeetle IDE).

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

techielew•1/16/24, 6:41 AM

This is very easy to read. Thanks!

My first question is what does this mean:

“The Beetle Boards will get special attention in Embeetle IDE.”

techielew•1/16/24, 6:49 AM

My 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?

techielew•1/16/24, 6:50 AM

What is the cost at Eurocircuits? Have you considered a kickstarter?

Petr Dvořák•1/16/24, 6:56 AM

@techielew Because of the Chinese chips, I would consider JLCPCB or similar companies. Everything else probably brings more headaches and higher cost.

Petr Dvořák•1/16/24, 6:57 AM

Another plus is that JLCPCB offers 3D printing and CNC machining. @kmulier can design an enclosure or some kind of accessories easy to order there.

Padmalaya Rawal•1/16/24, 10:15 AM

I 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

kristof-at-embeetleOP•1/16/24, 12:35 PM

Thank 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:

Eurocircuits (800 euro for 10 pieces, this includes assembly)
JLC
PCBWay
OSH

Debugging Arm Cortex-M Microcontroller Firmware in the STM32CubeIDE

Firmware developers always want to hit the "easy button", especially when debugging large professional development projects. A common way of achieving this is by using the serial terminal rather than leveraging professional debuggers.

But as codebases grow and firmware becomes more complex, these shortcuts can quickly become huge time sucks, an...
