Green circuit board with four RJ45 ports and two SFP cages

NaSR

NaSR 4-port 2.5GbE network switch

SKU CH-110A-VMWBS

A router development board with MediaTek Filogic 880 SoC, 4GB or 8GB DDR4, four 2.5GbE LAN ports and dual 10GbE SFP/RJ45 combo ports

  • Four 2.5GbE LAN ports for fast wired NAS links
  • MediaTek MT7988A quad-core ARM Cortex-A73 SoC delivers 30K DMIPS
  • Dual 10G SFP and RJ45 combo ports enable 10G uplinks
  • 4GB or 8GB DDR4 RAM with 8GB eMMC and 256MB SPI-NAND storage
  • OpenWRT support on 26-pin GPIO plus miniPCIe and M.2 expansion slots

MediaTek Filogic 880 SoC

The NaSR board integrates a MediaTek MT7988A (Filogic 880) quad-core ARM Cortex-A73 processor clocked at 1.8 GHz. It targets developers and advanced users building custom OpenWRT routers, Wi-Fi 7 access points, or smart home gateways. Buyers who need a ready-to-use consumer router with a polished web interface are not served by this bare development board.

Passive cooling and 12 V input

The platform draws power from a 12 V DC source and relies on passive thermal management suited to its integrated SoC design. No active fan or heatsink dimensions are specified, so acoustic output remains minimal in typical deployments. Installers requiring forced-air cooling or specific thermal thresholds must validate the chassis independently.

GPIO, M.2 and miniPCIe expansion

A 26-pin GPIO header exposes UART, I2C, SPI, PWM and I2S for peripheral development. Three M.2 B-key slots accept 5G modules over USB 3.2, while two M.2 M-key slots support NVMe storage via PCIe 3.0 x1. Two miniPCIe 3.0 x2 interfaces allow Wi-Fi 7 NIC additions. Users without soldering or kernel-configuration experience will find limited benefit.

Questions about this item

How do I install the BPI-R4 Pro board and what step do people miss?

Mount the board in a 12 V enclosure, connect the 4×2.5G RJ45 LAN ports and the 10G SFP/RJ45 combo ports, then flash OpenWRT to the 8 GB eMMC before first boot.

What maintenance or replacement will the BPI-R4 Pro need later?

The 128 MB SPI-NAND flash and 8 GB eMMC are soldered; only the MicroSD card, M.2 NVME SSDs and miniPCIe Wi-Fi 7 cards can be swapped.

What limit appears first under sustained load on the BPI-R4 Pro?

The MediaTek MT7988A SoC reaches its 30K DMIPS ceiling and the passive 12 V cooling becomes the bottleneck before the 36 Gbps Wi-Fi 7 throughput saturates.
