Advances in user-interface demands, easily seen in slot machines, show apparent demand for higher video performance. The OKDO Rock 5B can support up to three displays, making for a comfortable base for arcade projects. Furthermore, its high computing power makes it an attractive Raspberry Pi alternative.


A large board with high connectivity potential

Placing the OKDO Rock 5B next to the Raspberry Pi 4 leads to the results shown in the figure - obviously, the single-board computer is larger than its colleague. This, however, also has benefits - a careful look shows that the Rock 5B has two full-size HDMI outputs, whereas the Raspberry Pi 4 requires (often flimsy) HDMI adapters.

Furthermore, external storage can be added via multiple interfaces. In addition to the PCIe interface on the top, there is an eMMC module at the bottom. These two are interesting not only because of the potential for memory expansion but also due to their high vibrational robustness.
