NanoPi is a new Linux development board powered by Samsung S3C2451 ARM9 processor with Wi-Fi and Bluetooth LE connectivity, connectors for a camera and an LCD display, as well as two expansion headers including a 40-pin “Raspberry Pi compatible” header.
... The board is said to run u-boot, a Linux distribution based on Linux 4.1 and Qt, as well as Debian. You can download firmware images, source code, and schematics (PDF only), and checkout the Quick Start Guide to find out how to get started with a PC running Ubuntu.
NanoPi launch is planned for the 1st of August, and it will sell for $16, although I’m not sure whether shipping is included. Visit nanopi.org for details.
