Thanks to the friendly lot at Zidoo we can have a close look at the
Zidoo M6: RK3566 development motherboard a bit of a Beast,
Not aimed the Home User but maybe of interest if you are into this type of thing
More for the Power User or Industrial, Digital signage and other AIot products.

It has a lot going on the Inside as you will read and see in the following Photos:

The Box


What's in the Box: Power supply AU type remote and a Very good looking HDMI cable:


Front: Power Switch: Power LED Headphone Socket


Rear: the Usual HDMI, Ethernet, SPIDF USB Micro OTG, HDMI and Serial Port


Side one only: USB and Tf card slot


Remove the base:


Out with the PCB



Lots going On here: No 5g on the Unit I have:


And here just a little going on here:
