Sorry for my slow replay I propose that we create a bare carrier board with connectors for different SOC modules and different peripherals/storage This approach would maximize the combinations that can be tested using a single base board I would propose that we create the boards stackable with d

Hi Alin, That is basically the idea. We will have a SODIMM in the baseboard that will accept different CPU/MCU modules. The baseboard will have some basic components (most common in many NuttX boards and low cost) and connectors to let people to test different devices. We are not planning to cr

Hi Tomek, Thank you for attending the event. We will mix the two possibilities: we will have basic and most chips (and low cost) soldered on the board and we will have connectors available to people to test other modules. This way the board will be useful for testing purposes (to quickly and eve

Hi Sebastien, Thank you very much for this observation! Our plan is to do it at JLCPCB :-) BR, Alan On Mon, Sep 8, 2025 at 4:54 AM Sebastien Lorquet wrote: > Hello again, > > Once again I send emails too fast... > > > SODIMM is great but with the nuance that it requires a 1mm thick PCB, > an

Thank you Alan for leading this great initiative and everyone paritcipating :-) Sorry I was on the trip yesterday, could only for a moment on a train station, then I lost connectivity :-( This DIMM DDR2 SO-DIMM connector is nice for the CPU board aka "compute module" using similar connectors :-)

Hello again, Once again I send emails too fast... SODIMM is great but with the nuance that it requires a 1mm thick PCB, and that could become more annoying than enig. I've made some nice 1mm PCBs at JLCPCB but not all factories are able to deal with it, specially the cheaper ones. Some a

Just a small idea: A couple storage devices could be on there for testing various file systems. I'm thinking NOR flash, NAND flash and an EEPROM would be good additions. They can just be small in size for testing purposes. If you want to save on pins, you could use a single spi bus & CS line for a

Hi Everyone, Thank all participants of the meeting about the NuttX Standard Board. For those who were unable to attend, the video is available on YouTube: https://www.youtube.com/watch?v=keZAZ8GiYzI Just a summary of our meeting today: - It was defined that we should use the DIMM DDR2 SO-DIMM.
