MirkoPC -> CM4 carrier board

Yet another Raspberry Pi Computer (non-official carrier board for CM4).

Similar projects worth following
Carrier board for Raspberry Pi Compute Module 4.

Main features:
- full support of the Raspberry CM4 module,
- M.2 2242/2280 M-Key slot (PCIe x1 Gen2 5Gbps),
-Wifi 2.4GHz/5GHz + Bluetooth 5.0 BLE (CM4 module),
- MicroSD card slot,
- extra eMMC 5.1 memory (standard FBGA-153 chip),
- 4x USB 2.0 ports (Host mode, Type A connectors),
- Gigabit Ethernet RJ45 with IEEE1548 support,
- 2x HDMI 2.0 ports (4K @60Hz),
- 2x MIPI CSI camera interfaces,
- 2x MIPI DSI display interfaces,
- USB-C for power supply (5VDC@3A) and for boot mode (device),
- dedicated power supply connector,
- high-quality audio DAC I2S (32-bit/384kHz) with headphone amplifier (DitectDrive, 128mW output power),
- RTC clock with battery.

Here you can find a short introduction to the MirkoPC board by Jeff Geerling:
https://www.youtube.com/watch?v=4Womn10v71s&t=10s

PCB is 4-layer, with impedance control.

PCB dimensions: 100 x 100mm.

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

I will receive PCBs boards in 3 weeks (up to end of Feb), due to chinise 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:

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...

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

  Are you sure? yes | no

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

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

  Are you sure? yes | no

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

  Are you sure? yes | no

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

Thx.

Can you put 5 more cm4 somehow on it?

  Are you sure? yes | no
