NanoPi R4S as Soft Router

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

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. 

Current price: US Dollar

  • 1GB with metal case: $67
  • 4GB with metal case: $78

Hence,  it’s good device as soft router, much powerful, but not cost value one.
