MirkoPC -> CM4 carrier board

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)

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.

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.

Here you can find a short introduction to the MirkoPC board by Jeff Geerling:

So far I tested successfully:

- installed CM4 Lite, CM4 (+8GB eMMC), CM4 Lite with WiFi/BT,

- GbE ETH,
- 4-port USB hub 2.0 (connected keyboard, mouse, pendrive, USB Audio DAC),
- M.2 PCIe socket -> connected NVMe SSD drives Sandisk (2242 size, 3V3 @1.5A) and Kingston (2280 size 3V3@3A),
- Coral TPU (initially, not supported yet by CM4)
- USB-C (power/data),
- boot from USB-C,
- HDMI #0, HDMI #1,
- RESET button,
- power switch,
- 2-pin pwr connector,
- RTC + battery backup,
- temp. sensor,
- 2x status LEDs,
- buzzer,
- MIPI CSI cameras outputs (#0 & #1),
- overclocking CM4 up to 2.21 GHz,
- fan connector and dedicated heatsink with 5V fan,
- DAC + headphone amplifier,
- external eMMC BGA153 v5.1 IC chip (8GB FORESEE),
- @volumio (+ DAC + usb + eth),

- M.2 3V3 max. current

Fully assembled MirkoPC with installed SSD NVMe drive (2280 size):

Tested with SD Card:
And also with external eMMC BGA153 v5.1 IC memory:

Yeah, WiFi definitely is working. BT also.

80 Mbps... Nice.

After soldering.

MIPI CSI-2 interfaces for Cameras are working.
