NanoPi R4S as Soft Router
- An American company made 0.7nm chips: EUV lithography machines can’t do it
- CVE-2007-4559 Python vulnerability ignored for 15 years puts 350,000 projects at risk of code execution
- RISC-V only takes 12 years to achieve the milestone of 10 billion cores
- 14000 cores + 450W: RTX 4080 graphics card perfectly replaces the RTX 3080
- Big upgrade: The difference between Bluetooth 5.0 and 5.2
- Geeks Disappointed that RTX 4080/4090 doesn’t come with PCIe 5.0
- What are advantages and disadvantages of different load balancing?
NanoPi R4S as Soft Router by Flashing OpenWRT. It comes with two reall Gigabit Ethernet ports: one as WAN; another as LAN. also with ultra small size: 72x72x29mm (including case), bigger than NanoPi R2S: 61x60x26mm (including case).
Highlight comparing with NanoPi R2S:
- CPU: RK3399, more powerful
- Two real Gigabit network port
- 4GB LPDDR4 optional
- USB-C Power supply

The official image of OpenWRT has not been released by the manufacturer.
Peformance of NanoPi R4S
Disadvantage:
- Bigger than NanoPi R2S
- More expensive than NanoPi RS2
- USB-C power adapter more expensive
- Openwrt is not supported officially yet.
Conclusion
Overall , Naopi R4S is mch powerful as soft router. Its performance exceeds some low-end x86 CPU, but do believe the multi-task ability still weaker than x86 software. 4G RAM seems little waste to be a soft router, but potential to do more things in future.
Hence, it’s good device as soft router, much powerful, but not cost value one. NaoPi R2S with good value although its CPU is weaker than R4S.
