The NanoPi M1 is an Allwinner H3 based ARM board designed and released by FriendlyARM for hobbyists, makers and electronic fans. It is only two thirds the size of the Raspberry Pi. It is open source. It works with Ubuntu MATE, Debian and etc.
The NanoPi M1 uses the Allwinner H3 Soc. It integrates Ethernet, IR receiver, video/audio output and supports HDMI and AVOUT. It can be powered via the MicroUSB port
In such a small board it still integrates rich interfaces and ports. Besides the popular HDMI, Ethernet, USB-Host, USB-OTG, DVP camera interface and AVOUT (audio and video) it has an onboard Microphone, IR receiver, a serial debug port and a Raspberry Pi compatible 40 pin GPIO pin header.
