Radxa, a Brazilian developer of single-board computers (SBCs), has started sales of its Rock Pi 4C SBC that is designed for ultra-cheap ultra-compact systems. 

The Radxa Rock Pi 4C SBC is based on the Rockchip RK3399 system-on-chip (SoC) that was originally designed for inexpensive Google Android tablets and therefore has a rather decent feature set and performance. The board could potentially power an entry-level home-theater or entertainment PCs project or a ‘typewriter-class’ office PC that does not need significant performance.
