New Product Ideas / LiPo-UPS-5V or MOD-UPS-5V
Last post by ilario - May 29, 2025, 07:36:17 PM
Dear all,
I am used to A64-OLinuXino, but for the next project I am considering the iMX8MP-SOM-4GB-IND + iMX8MP-SOM-EVB-IND combo.

What I miss from the A64-OLinuXino is the LiPo battery connector, that has proven to be very useful and effective against power cuts.

So a new product idea would be an external board that acts as a UPS for the 5V power. Optionally, this board could have an UEXT connector for informing the main board on the status of the battery (%, charging status...). Ideally, the LiPo battery would be discharged during power cuts and recharged when the power is back.

It would be a board with the following connectors: 5V inlet (barrel plug socket), 5V outlet (either a short cable ending with a barrel plug or a block terminal), LiPo battery connection, and, optionally, an UEXT connector for communicating to the computer the status of the battery.

This is so nice of you, thanks!
My de-soldering skills are very bad (e.g. see my desoldering strategy here), so I would certainly destroy the board if I did it myself.

I've brought in the updated footprint files and everything looks good in the Kicad project now.

Thank you for the help!

These haven't been recently updated and it is probably missing. Will update them today with latest ones, notice that there are sub-folders for KiCAD 6 and KiCAD 7 (since these are incompatible). If you are using KiCAD 9 then probably use the footprints for the KiCAD 7 subfolder.

NXP / IMX8 footprints
Last post by petey815 - May 28, 2025, 09:13:54 AM
Hello friends,

I am looking at the IMX8MP SOM/EVB with the hope to test it out and adapt parts of the board layout for a personal project.

I've opened the files up in Kicad 9, and while there were a few migration steps needed due to the original layout being done in kicad 5, it looks good.

However, I cannot seem to find the footprint that is called out for the IMX8, specifically, 'OLIMEX_IC-FP:FCBGA548_Pitch-0.5mm_Ball-0.25mm_Dimensions-15x15x1.5mm'

I downloaded the OLIMEX_IC-FP from here, but it does not seem to have the FCBGA548 package
https://github.com/OLIMEX/KiCAD/tree/master/KiCAD_Footprints/OLIMEX_IC-FP.pretty

I also had some trouble finding the 'OLIMEX_IC-FP:SOT949-6(HVQFN56)' package for the power management IC

Would it be possible to include these footprints in the Github repository with the rest of the Kicad files, or perhaps I might be looking in the wrong spot?

Thank you for the help! and hats off to you for making the board design open source, so people can learn what goes into these type of designs   :D

By the way if you wish to purchase it, we might desolder the SPI for you - add it as note during the checkout (it is usually in step 3 of 5 at the bottom of "shipping options") and drop us an e-mail at support@olimex.com. It is important for us to see the note.

Yes, the first one - if you wish to use the eMMC from the module with iMX8MP design you should desolder the SPI always.

The SPI memory of Flash-e32Gs16M won't work with iMX8MP-SOM-EVB-IND. The reason for the miss is that the module works fine with RK3328 and STMP designs but they are working at 3.3V (unlike the iMX8MP that works at 1.8V).

It is not very good practice to have a 3.3V memory to the 1.8V port of the iMX8, this might damage the main CPU. Or level shifting would be required.

The eMMC memory would work at 1.8V tho. If you wish to use that extension module for the eMMC, my advice would be to desolder the SPI memory.

Will see how things get done in next revisions.

Quote from: jch on March 22, 2025, 09:25:44 PM> as A64 is already considered as "old" SOC probably no one is / will be working on this

In that case, what's the suggested replacement for the Olinuxino-A64?

No answer, so seems that so far (2025-05-27) there is no suggested replacement.

I just realized the existence of the System-on-Module (SOM) products line, and you could consider trying those products instead. The newest being iMX8MP-SOM-4GB-IND + iMX8MP-SOM-EVB-IND combination (and maybe including also Flash-e32Gs16M but check out this topic https://www.olimex.com/forum/index.php?topic=9808.0).

Not as convenient as a Single Board Computer, as it does not have a nice box, but it looks like a viable option to me.

NXP / Flash-eXXGs16M and iMX8MP-SOM-...

Dear Olimex team,
I was checking into the iMX8MP-SOM-4GB-IND + iMX8MP-SOM-EVB-IND combo and specifically into its accessory Flash-e32Gs16M.

In the description page of the accessory, there is this eerie text:

QuoteFits iMX8MP-SOM-EVB-IND, but only eMMC would work out-of-the-box, there is voltage mismatch on the SPI flash lines (SPI flash should be desoldered).

What does it mean?
Should I desolder the 16 MB SPI memory in order to be able to use the 32 GB eMMC one?
Or can I just plug it in and use the eMMC one, with the SPI just not showing up?
