for NanoPi R5S ("R5S " for short) is an open source mini development board with dual 2.5G+Gigabit triple network ports designed. It uses Rockchip RK3568B2 as the main control processor, equipped with 2GB/4GB LPDDR4x memory, and 8GB/32GB eMMC flash memory, and supports TF card to start and run the system. for R5S has rich interfaces and compact layout. The motherboard size is only 90x62mm, and an integrated CNC anodized aluminum shell can be installed as an option. It has an output interface and can run for Android, for desktop system and for Buildroot system, and can also be used as a line mode that geeks like; and it can decode and play 4K60p 265/264 and other format videos. The for R5S also has an M.2 NVME solid-state drive interface and two USB 3.0 interfaces, and supports USB C port PD fast charging power supply. There is no need to worry about insufficient power supply when connecting an external mobile hard drive. It is a portable storage and processing tool for photo and video enthusiasts. for R5S integrates multiple network ports, NAS and video playback, which is very suitable for players to discover and explore and create their own unique gameplay. for NanoPi R5S has one Gigabit Ethernet port and two 2.5G network ports. The Gigabit Ethernet port is directly derived from the SoC, and the other two 2.5G network ports are transferred by PCIe.The transmission rate of the Gigabit Ethernet port directly derived from for NanoPi R5S is 941Mbps, and the receiving rate is 941Mbps; the transmission rate of the two transferred 2.5G network ports is 2.10Gbps, and the receiving rate is 2.30Gbps.
