-course, but gives you much bang for [the buck][5]!
+The [NanoPi R2S][9] is a compact, affordable router board built around
+the Rockchip RK3328, a quad-core Cortex-A53.  With two Gigabit Ethernet
+ports, a USB 3.0 port, and a reset button, it has everything you need

+firewalling, and VLANs at wire speed, it is an excellent choice for
+anyone looking to run a proper network OS at home without breaking
+the bank.
