help NanoPi R4S FAQ
Why is the NanoPi R4S popular for OpenWrt builds?
The NanoPi R4S uses Rockchip's RK3399 SoC and has two Gigabit Ethernet ports, which makes it practical as a small router. It is powerful enough for routing, firewalling, and moderate SQM compared with many low-end consumer routers.
Does the NanoPi R4S have built-in Wi-Fi?
No, the R4S is usually treated as a wired router board. If you need Wi-Fi, you normally add access points separately rather than expecting the NanoPi to act like an all-in-one home router.
Which RAM versions of the NanoPi R4S matter for OpenWrt?
FriendlyElec has sold R4S variants with different memory configurations, commonly including 1 GB and 4 GB versions. For ordinary routing, 1 GB can be enough, but the 4 GB model gives more headroom for packages and services.
What storage does the NanoPi R4S boot from?
The R4S typically boots from a microSD card, so card quality matters for reliability. Many OpenWrt users keep the install lean and back up the configuration after setup.
