MirkoPC REV1.1 finally relesed. Please read the project log for more details and also follow me on twitter.

2021-04-14

All the interfaces were successfully tested. All the features are working.

The first batch was sent to the first users (8 boards).

You can check my github page (for technical details) and twitter account (for the current project status).

2021-02-10

Project is under development - I ordered PCBs and assembly for passive components.

I will receive PCBs boards in 3 weeks (up to the end of Feb), due to the Chinese new year.

Then I need about 1-2 weeks for assembly rest components (ICs, connectors) and to bring up hardware.

Here is the 3D model in PDF format and STEP file:

https://github.com/mfolejewski/MirkoPC

The hardest thing in this project is the PCIe M.2 slot implementation. I'm not sure for 100% if this will work but it seems that the design should be OK.

I would like to test SSD NMVe drives and Coral Edge TPU modules.

Target applications:
· Machine learning platform (Coral Edge TPU)
· Cloud computing
· NAS server
· BOINC client
· Small server
· Home automation controller
· Smart controller
· HiFi media player (Volumio, RuneAudio)
· Home media center (OSMC, OpenELEC, XBMC/Kodi)
· and many more...

3D enclosure model for MirkoPC REV1.1
Mirko • 11/18/2021 at 23:10 • 0 comments

MirkoPC REV1.1 -> 3D enclosure model -> here you can download STL files:

https://github.com/mfolejewski/MirkoPC/tree/main/3D_ENCLOSURE

After a few months of waiting, I can publish now this model for free. Sorry about the delay. Feel free to print (only if you have a MirkoPC REV1.1 board).
IC shortage
Mirko • 06/21/2021 at 10:49 • 1 comment

Still, now it's very hard to order any integrated circuits.
I really don't know who will manufacture the next batch.
After I will manufacture the 2nd and 3rd order batches I have to close or freeze this project due to a very hard situation on the market with components - IC shortage. Most of the ICs have lead time ~52 weeks.
Here are the examples:

EMC2301:
PCM5100A:
USB2514B:
ATTINY5:

Hear Hackaday community!
I have to say sorry! Sorry about my no answer, sorry about my delayed response, sorry about the whole situation.
I had two weeks off due to my personal issues.

This project beat me - to much work, to much assembly, to much things to do in the same time for a single person, I'm overloaded.

I tried to assembly the boards with 2 colleagues but even for that was too much work for a small team. Now I'm working alone and I really don't know that the next 2 weeks should be enough for finish the assembly of the rest of the 30 pcs.

Sorry! This project was one of the stupidest idea that I made (due to overloading).
IC shortage and issues with partially assembled and ordered PCBs - these things beat me - because I tried to manually assembled all the boards with missing components.

For next few days I will prepare and test 20 pcs for the first customers that paid the initial payment - please see the picture below.

After I will finish the whole assembly and test the rest boards (about 50 pcs and for another project - bitpirat - about 15 pcs) I will close any manual assembly and testing.

The next batches will be manufactured by external companies and boards will be offered by at least one distributor from Europe (Denmark or UK), if everything will be OK.

Again sorry about that situation.

Dear Hackaday community!
Really sorry for my delayed response and my project update and status. I have to say 'so sorry'.
Project delayed about one month (I planned to start shipping in the second half of May), but the current plan for shipping is the first half of June.
I need about 2 weeks to assembly the rest of the components. I have all the needed components.
I will assembly manually only 10 pcs (due to is too much work for one guy), the rest of the PCBs I will order manual assembly at some small EMS company service.
During this manufacturing stage I faced on few hard issues:
1. the biggest issue - component issue, almost all integrated circuits are not available on market (empty stock), due to Covid, pandemic and automotive industry mass production.
I sourced components from many different shops, such as Mouser, DigiKey, TME, LCSC, Texas Instruments, Allegro, Kamami, and even Aliexpress and TaoBao.
2. I had 1 week of delay with my PCB manufacturer (DFM review for my approval).
3. I had 1 week of delay due to FedEx service and customs procedure and shipping delivery.
4. In total I have about 3 weeks of delay on the manufacturing stage due to external issues.
5. Now I need about 2 weeks for manual assembly and about 1 week for the shipping process.
Things to do:
1. manual assembly 50 pcs (by me and some EMS company)
2. create simple firmware for push-button controller (microcontroller)
3. test all the boards and functionalities
4. prepare the shipping for all users and customers
5. update and prepare Github documents and user manual
2 weeks ago I decided to left the company, where I worked as a regular employee, to have more time for the MirkoPC project and future designs and soon I hope to create my own company. Next week I will be free for 100%.
The good news is that MirkoPC GEN2 (R1.1) will have a colored pin header (HAT connector) and unique power switch (tactile switch).

Please forgive me for that situation, but I'm just want to finish this project and to deliver ASAP even if this is impossible these days (IC shortage times and pandemic).
So, summarizing I need about 2 weeks to assembly and 1 week for shipping (I hope).
I will send over 40 packages to all my users and customers so please be patient and keep your fingers crossed! Wish me luck!
I attached the partially assembled boards (5 pcs).
Regards!

Due to IC shortage times I sourced components from: Mouser, DigiKey, TME, LCSC, Aliexpress, Texas Instruments, TaoBao, Kamami, Allegro.

Nothing will stop me to finish this project... :-)
2021-06-26 assembly issues
Mirko • 05/28/2021 at 06:41 • 0 comments

just a quick preview - this is what the 2nd and 3rd batch looks like.

I can see two issues for now:
- slide switches on 3rd batch are damaged, too high temperature on the reflow process
- some mezzanine connectors need to correct its placement
2021-06-26 quick preview
Mirko • 05/28/2021 at 06:40 • 0 comments

For the 3rd batch, I changed the FFC connectors to similar models as on the original CM4-IO board.

This is still a prototype, but in the meantime, I changed a lot of things and I fixed a few issues.

I hope that this time this will be a stable version, ready for mass production.
2021-06-26 received 2nd and 3rd batches

2021-06-26:
Today I just received 2 boxes from Fedex.
2nd and 3rd batches #MirkoPC

I'm happy and a little stressed if everything will be OK.

Keep your fingers crossed, lot of work to do.

There is no space for mistakes, everything has to work 100>#/span###
MirkoPC manufacturing update
Mirko • 05/17/2021 at 05:19 • 0 comments

Dear #MirkoPC community!

2nd and 3rd batches are on the way.

I need about 1 week to process the customs procedure and then up to 2 weeks to assembly the rest of the components (missing ICs and connectors).

Lot of work to do yet!
I'm very excited and I hope that the boards will be working 100%.

There is not space for my mistakes.

Hi, I hope everything is OK with you.

I'm just chasing up if these boards are available to buy?

Its doesn't look like you've been on here for a while.

I hope everything is good with you, and I'm sorry to hear about you having to deal with personal issues.

Take care.

hi,

Ich habe heute dieses Projekt entdeckt und bin begeistert 🤩

Leider scheint das Projekt eingeschlafen zu sein oder ich seh nicht wie und wo man das Produkt erwerben kann.

Vorschlag: macht ein Kickstarter daraus und du wirst vielen Leuten was gutes tun und selbst dabei auch noch Geld verdienen.

What's the price?

BTW, managed to fit a Rev 1 board into the 3D enclosure. The form factor was spot on, but I had to give up the uHDMI port, uSD slot, and file the hole for the switch a little bigger. If there's a way to add pictures in a post, I'd show everyone following this thread. Keep up the great work you're doing.

You have probably the REV1 (old version) of the project. I have to talk with my colleague about the STL file to publish. Unfortunately, he is now on a 2-weeks vacation (I have some issue with him publishing STL files, because initially, he agreed to publish the 3D models, but later he changed his mind).

Hey there, I would like to get this board for myself. I saw a video on Jeff Geerling's Channel and about booting a pi module using your board. This is totally great. Also, I would kile to create a case for this board, from metal. I do have access to CNC, so this way I will be able to get a model right away, if I have a correct configuration for the port exits.

This project looks awesome, maybe this has already been asked, i honestly looked around but maybe i'm blind .. excuse me if it has been answered already : what is the target price when finished ? Is there some ways this could be made compatible with the PoE Hat ? I was thinking of using this to build a headless one wire bitcoin node with a 1TB NVMe SSD on it.

Are you sure? yes | no

Mirko wrote 05/27/2021 at 07:15

As a prototype this carrier board cost 65 USD, for mass production hard to say now, I'm during manufacturing next prototype batches. PoE compatibility - so far no, because this feature require to redesign the board (RJ45 connector is placed far away from HAT connector.)

Are you sure? yes | no

jacktronics wrote 05/27/2021 at 12:11

Thanks for the answer, I guess I can do the PoE externally if I really wanted to, this board is still the best option for this little project from my perspective so good luck with your endeavor :-)

Pewnie 10G lub więcej nie byłoby złym pomysłem, tylko tutaj potrzeba $$$ bo to nie jest już amatorski projekt, tylko coś takiego trzeba wykonać zespołem kilku ludzi (hw/sw/fw/testy). Dla mnie żaden problem projektować ultra zaawansowane projekty hw - fpga, dsp, high-speed interfejsy no problem, jedynie trzeba sporo siana od bociana :)

Dlaczego ta płyta jest pozioma? Nie lepiej ustawic ją pionowo?
Lepsze odprowadzanie ciepła. I nawet drukowane opakowanie miało by
lepsza termikę.

Dla mnie ważne jest zasilanie i oszczędzanie prądu. Czy jest
jakis sposób by ograniczyc taktowanie np. ethernetu, pamięci, albo
wręcz dodać 4 fpga czy procesory sygnałowe. Fajnie było by zrobić

pozioma? to jest płytka rozwojowa, do testów deweloperskich, jak cm4-io board.

Co do redukcji mocy (obniżenie taktowania) - proszę zadać takie pytanie na oficjalnym forum Raspberry Pi Compute Module albo poszukać na blogu Jeffa Gerlinga.
