Anyone searching for an alternative to the Raspberry Pi mini PC may be interested in the Libre Computer ROC-RK3328-CC which has been developed thanks to a partnership between the Libre Computer Project and Firefly. Prices start from $35 offering 1GB of DDR four RAM but if your budget will stretch 4GB are available for $80.
As the name suggests the mini PC employs a Rockchip RK3328 SoC offering four ARM Cortex-A53 cores running up to 1.5GHz and ARM Mali-450 MP2 graphics. The mini PC is capable of running Android 7.1.1 and Ubuntu 16.04 by Firefly, and the Libre Computer Project also has Ubuntu 18.04 and Debian 9 images available that make use of Rockchip’s Linux 4.4 LTS kernel.
Offering a similar size and form factor to the Raspberry Pi the small development board measures 85 x 56 mm in size and is equipped with 2 x USB 2.0 ports, 1 x USB 3.0 port, HDMI 2.0a, Gigabit Ethernet and micro USB port for power.
