The Rock Pi X is like a cross between an Atomic Pi and a Raspberry Pi, but even more affordable. Radxa equips the 85 x 52 mm developer board with an Intel Atom x5-Z8300 processor, up to 4 GB of LPDDR3 RAM, along with a host of ports and connections including an HDMI 1.4 that can output in up to 4K. The Rock Pi X has a 40-pin Raspberry Pi compatible header too and supports several OSs including Android, Windows 10, Ubuntu 18.04 and other Linux distributions. The Rock Pi X will start at US$39 and rise to US$75 for the most expensive model.
