Quantum Tiny Linux Development Kit – With SoM and Expansion Board

100 % of 100

Quantum Tiny Linux Development Kit consists of a core board which is the SoM (System on Module) and an expansion board as the carrier board. 

The SoM, Quark-N, is based on Allwinner H3, Quad-core Cortex-A7, and ARM Mali400 MP2 GPU. The carrier board, Atom-N, leads out a row of golden finger pins to realize I/O expansion, expand SPI, I2C, UART, GPIO, and other useful interfaces.

The kit may be the smallest Linux development board on the market which is suitable for scenarios such as a personal server, intelligent voice assistant, and robotic development.

Seeed strives to provide professional manufacturing services and advice to support makers share their ideas with the world, from prototyping, mass production to selling to a global audience. Seeed Studio provided Zhihui with a complete service from PCBA prototyping, customization and consignment services, bring the product from idea to market. Meet this open-source, 35 x 40mm Linux Development Kit with SoM and Expansion Board that runs Ubuntu Core on a quad-core Allwinner H3 

About the designer

Zhihui, a full-time AI algorithm engineer and an enthusiastic maker, likes to share videos of his creations in his spare time. He has more than half-million fans on the BiliBili, video sharing platform, and his most popular video surpassed 4 million views. Seeed was impressed by his outstanding ideas, so our team reached him out and came to a cooperation agreement of Project Quantum. Seeed provides him with a full range of services, such as engineering design, mass production, product operation, and product promotion. 


  • Ultra-small (31mmx22mm) and highly integrated Quad-core Cortex-A7 Linux SoM (System on Module)
  • Expansion board (40mmx35mm) with rich peripherals and interfaces: Microphone, Gyroscope, Accelerometer,4 x Buttons (GPIO-KEY, Uboot, Recovery, Reset) and a TFT display
  • Integrates a complete ARM-Linux system for advanced development
  • Ability to design your own baseboard due to the M.2 interface
  • Wide range of applications such as a personal server, intelligent voice assistant, and robotic development.


Quantum Tiny Linux Dev. Kit is possibly the smallest Linux development board on the market, a highly integrated kit with quad-core CPU that can run Linux at only 40mm x 35mm, which also includes network connectivity. It is suitable for scenarios such as as a personal server, intelligent voice assistant, and for robotic development.  

The SoM is called Quark-N, based on Allwinner H3, Quad-core Cortex-A7, and ARM Mali400 MP2 GPU. The 6-layer high-density gold PCB design integrates a complete ARM-Linux system (CPU, DDR, eMMC) in a 2x3cm space. Also, most of the GPIO is led out by the board through the M.2 Key-A golden finger interface to minimize the bottom board design difficulty. You can easily design your own base plate with two-layer boards to realize your interesting ideas.

The carrier board is called Atom-N, and Quark-N is connected to Atom-N through the M.2 interface. Atom-N leads out a row of golden finger pins to realize I/O expansion, expand SPI, I2C, UART, GPIO, and other interfaces to facilitate the completion of your own design. Also, it is equipped with a microphone, MPU6050 motion sensor (accelerometer and gyroscope), onboard 4 buttons (GPIO-KEY, Uboot, Recovery, Reset), IPS display, Wi-Fi/Bluetooth connectivity which greatly expands the possibilities with this product.
