The ODROID-C0 is a computer for those who wish to make a more flexible and portable applications. It is a minimized hardware version of the ODROID-C1+. Battery power circuit is fully integrated. Just attach a 3.7V Li+ battery and make it mobile. It is highly suitable for IoT projects, wearables, and other applications that require a lightweight device. 

All the ODROID-C1/C1+ OS images are fully compatible with the ODROID-C0. Some of the modern operating systems that run on the ODROID-C0 are Ubuntu, Android, Arch Linux, Debian, and OpenELEC, with thousands of free open-source software packages available. There are also plenty of custom OS available for using the ODROID-C0  as a multimedia center, Kodi, gaming station, headless server and much more at our ODROID community.
