Made by a Chinese engineer and content creator Zhihui Peng, the “Quantum Tiny Linux Development Kit” is a small SBC that’s smaller than an ID photo, powered by an Allwinner H3 SoC, and equipped with 512MB of RAM and a 16GB eMMC flash.
It’s a design with a 31x22mm CPU module with an M.2 edge connector and a 40x35mm carrier board with a microSD card slot, WiFi 4 and Bluetooth 4.0 wireless module, a TFT display, two USB 2.0 ports, a 6-axis motion sensor, and a few buttons.

I’ve just realized the Quantum Mini was first introduced in 2020, and it has just resurfaced as people posted videos without many details, even failing to disclose the exact CPU… The Quantum Tiny looks to be an improved version with a different antenna type for better wireless performance, an optimized PCB layout moving the fan solder joints to the top, and without Uboot and Recovery buttons.
There was no documentation or OS image for it when I first wrote about the Mini in 2020, and the documentation has improved since then. The board runs a modified Linux image (Debian-based with apt package manager) made for FriendlyELEC’s Nano Pi M1 SBC that has not been updated since 2021… It can be used as a microcomputer, a personal website server, a voice assistant, a smart home hub, and for image processing and robotics applications. xRDP is also installed on the image, so you can also access the desktop remotely, even if it lacks an HDMI port.
The Allwinner H3 was first introduced in 2014 for TV boxes, and then found in many low-cost SBCs in the following years, so Linux mainline support should be quite good thanks to work by the sunxi-linux community. The 4-year-old video below shows the original prototype and some demos.
The Quantum Mini/Tiny board has been around for many years, but I don’t think it’s been overly popular. Some reasons are that there were also many low-cost Allwinner H3 SBCs on the market, and its feature set makes its $58 price tag unattractive (up from $49.90 in 2020).
