Zidoo M9 Mini PC Review – Part 1: Unboxing & Teardown

Over the years, Zidoo has made TV boxes for the consumer market, and digital signage players for businesses. The recently announced Zidoo M9 aims at both markets, plus other applications such as IoT, robotics, and artificial intelligence.

Zidoo M9 is either sold as a board or a complete TV box reference design with a case, as it exposes all the usual ports of a TV with HDMI, USB, and Ethernet. But you can do more with internal connectors for cameras, PCIe interfaces, SIM card slot, MPI DSI and eDP connectors, and so on.

The company has sent me a review sample, so let’s first check out the accessories provided with the box, and have a look into the hardware design today, before testing the Android firmware in the second part of the review.

Zidoo M9 Unboxing

The package makes it clear Zidoo M9 “mini PC” looks like a TV box, but it’s also designed for other purposes like automotive infotainment, virtual reality, robotics and so on.

Zidoo M9 Teardown

Most people purchasing the mini PC for product development will likely want to open it. The two parts of the enclosure are fastened together via two screws. Simply remove the rubber pads close to the front panel, and loosen the two screws.

I wish they had made it a little easier to open, but after some efforts, I could take out the bottom cover with breaking anything.

We’ll need to remove two more screws to complete take out the board from the enclosure. The top cover holds two WiFi antennas.

We have more internal connectors with two MIPI CSI/DSI connectors, DVP camera interface, eDP (embedded DisplayPort) connectors, a PCIe M.2 socket for NVMe SSD’s, as well as a 42-pin I/O headers and a 4-pin header designed for a PoE module provided by the company.

A 32GB Samsung KLMBG2JETD-B041 eMMC 5.1 flash is used for storage.

Other notable chips/modules include a Realtek ALC5640 audio codec, an Fn-Link 6222B-SRB wireless module with 802.11 b/g/n/ac WiFi 5 up to 867 Mbps and Bluetooth 4.2…

as well as SIPEX SP3232EEA RS-232 transceiver for the DB9 connector / COM port.


The box is running Android 7.1, and Zidoo also provides an SDK for customization, but at the time of writing, I could not find either online. I’ll ask the company, but I may have to test the device with the pre-install Android 7.1 OS.

I’d like to thank Zidoo for sending the M9 mini PC for review. The device is not for sale online just yet, but if you have a commercial project in mind that could use the board or complete reference design you may contact the company via the product page.
