Mini Core Board
Quark-N may be the smallest Linux development board on the market, personal server, intelligent voice assistant robot development board. 6-layer high-density sunken gold PCB design, integrated complete ARM-Linux system (CPU, DDR, eMMC) on a 2x3cm space; board through the M.2 Key-A gold finger interface to lead most of the GPIO, the maximum minimize the difficulty of the base board design, can be used to easily design your own base board with two layers of boards, used to achieve your interesting works of creation.

Powerful expansion version
Atom-N, a companion expansion board to Quark-N, connects to Quark through the M.2 interface. Compared to more conventional card computers, Atom-N leads a row of gold fingers to enable IO expansion, extending SPI, 12C, UART, GPIO and other interfaces to make it easy to complete your own designs, adding a microphone, MPU6050 motion sensor, the On-board 4 buttons (GPIO-KEY, Uboot, Recovery, Reset), IPS display, Wifi Bluetooth module, which greatly expands playability and usability.
