Details

PCB is 4-layer, with impedance control.

PCB dimensions: 100 x 100mm.

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...

MirkoPC v1.1 -> under development...
Thank you all for asking me about purchase the carrier board.

I'm working on 2 topics:
1. to modify the project (minor changes)
2. to order all the components and PCBs (30 pcs)
REV1 assembled boards (beta)
Mirko • 04/09/2021 at 00:20 • 0 comments
Assembled REV1 prototype (beta)
Mirko • 04/09/2021 at 00:12 • 0 comments

PCB boards are ready for shipping to the first customers (the whole world).

I'm working on ordering the next batch and on the official user manual.
DSI LCD testing
Mirko • 04/09/2021 at 00:08 • 0 comments

Both MIPI CSI and DSI interfaces are working (cam #0, cam #1, disp #0, disp #1).

And finally, I can say: all the CM4 interfaces are working 100% on this carrier board without any circuit or PCB footprint errors.
News media and press releases

You can find more information about the MirkoPC project on the internet. Several press releases in the media about the project have been published so far.
The most important are listed below.
So far, most of this media news about the project was published thanks to the well-known IT enthusiast Jeff Geering by a demonstration of the new feature of booting a Raspberry Pi CM4 module from an NVMe disk based on the MirkoPC board.

I also would like to buy a couple of boards to test them. I'd buy more units if they work for my project as I think. Thanks.

Are you sure? yes | no

please send me DM. I'm working to order the next batch.

A *very* cool build! One of the first things that occurred to me is that it would be much easier to build into something else if there was a version with all ports on one side. (...or at most two, with one long side and one short.) That way, for example, folks could build a case that attaches to the bottom of a keyboard and have a 'keyboard PC' like the C64/etc.

(I'm sure that changing everything wouldn't take you more than a day or two. :grin: )

Are you sure? yes | no

The link is the same stuff, https://www.waveshare.com/product/raspberry-pi/boards-kits/compute-module-4-cat/cm4-io-base-b.htm, the price is $36

Are you sure? yes | no

jim ercy wrote 2 days ago

smaller item but less feature rich. It only handles 2230 and 2242 M2 ssd, does not have either a quality dac. That in itself prevent easy use as media center. Only 2 usb ports also.

Are you sure? yes | no

I'm interested with your project. I would like to buy one to play. How much does it cost?

Excellent. What is the cost and when it will be available?

If you are interested to purchase that board - just send me PM. Thanks.

I'm thinking about ordering the next batch or starting CrowdSupply campaign (a big issue -> time to market delay).

When I receive more such inquiries, maybe there will be enough of them to be able to order more PCB boards.

Are you sure? yes | no

Danny Martin wrote 04/08/2021 at 05:27

I would be interested in purchasing one of your boards. Can you provide cost and ETA on delivery?

Are you sure? yes | no

Pengfei Li wrote 6 days ago

Yes, I'm interested in this project. Can you modify your design a little bit? I am trying to use CM4 to build a WiFi 6 router which needs 5 ethernet ports and WiFi 6. The GPIO only needs 12 pins. Please send me email at szlipf@gmail.com to discuss this.

Are you sure? yes | no

Mirko wrote 6 days ago

a little bit? I don't think so :)

You can connect GbE port to the external multiport switch.

Adding an extra GbE switch is a quite complicated process (HW and SW).

Are you sure? yes | no

Pengfei Li wrote 6 days ago

Does m.2 port of this board support WiFi card?

Are you sure? yes | no

Mirko wrote 6 days ago

Not tested yet.

You can use CM4 with onboard Wifi + BLE module.

Are you sure? yes | no

Great work. Saw it in Geerling's video. When can we get one?

Can I Paypal you some money for an early finished and tested carrier board? You can contact me at redjr16@yahoo dot com.

Thx.

Yes. Very cool carrier board and project.

Can you put 5 more cm4 somehow on it?

Are you sure? yes | no
