ESP32-S2 Version of a Raspberry Pi CM3
« on: June 09, 2023, 08:25:29 am »
Hey Guys,

I made a ESP32-S2 Board in the footprint of the SO-DIMM-DDR2 which is the same as a Raspberry Pi CM3 and I also made it pin compatible with it!
I am also running a CrowdSupply campaign where I am looking for help to make the project real: https://www.crowdsupply.com/open-things/openthing-1-esp-cm3 <--

So please help me and subscribe in the link above if you are interested.

But of course the project is also fully open-source! You can find the project on Hackaday: https://hackaday.io/project/189526-so-dimm-esp32-s2-cm
or also on GitHub: https://github.com/open-thngs/so-dimm-esp32-cm
It is OSHW Certified already as well. So if you are eager to help me, give me feedback or anything! I would be very happy about it.

Thanks! Tell me what you think or also just ask questions!

It's fantastic. Where did you print this PCB from?

You mean the supplier for the PCB? I am always using PCBWay or JLCPCB for my prototypes because it seems to be the fastest. But once I am producing more I am going with a German PCB Assembly company (because I am living in Germany). It is not as cheap but also not very much more expensive. And I save customs and tax if I do that - and as well I have real contact person which I can talk to if there are troubles.

I generally like the idea of people asking for monetary support for their hardware/software projects but it strikes me a bit odd that you would make your very first post on this forum about your project.

I totally understand that - I also do not feel very happy about it because I would feel the same way tbh.
My issue is I only need 5 more subscribers to get to the next stage with that Project so it actually can be crowdfunded so I thought I give it a try in this Forum.

As well: I am not selling anything right now and I do not ask for money, I am just simply looking for people who are interested in this project. Of course I could fill this missing 5 subscribers with fake-mails or whatever, but whats the point of doing that, right? And as far as I understand this category where my post is in, it says: "show off". Thats actually what I am doing :)

But yes - I am not really active in this Forum or any Forum, I just prefer other ways like the Hackaday project pages or similar. And yes - I created the account just to ask and "show off" because I am missing this damn 5 subscribers. I hope you can forgive me :)

Interesting project. What would be optimal smt so-dimm connector model to put on my board if I use this? Last time I've checked landing patterns and accompanying  board holes looked pretty different for each manufacturer, and I couldn't figure out which part is most popular non out-of-stock solution.

I made a programmer board for this project but also in another project I used this one: https://www.mouser.de/ProductDetail/TE-Connectivity/1612618-4?qs=VZ9FDhhp7Sns0cx%252BBFDasQ%3D%3D
That works very well for me so far.
