Minimal standerd interface module, delightful price, comprehensive software support, a wealth of documents and communities, good looking, texture, to I.o.T new era

  • Minimal WiFi & Linux Module in NGFF M.2 as 22*42mm
  • MTK MT7628AN: 802.11n 2*2, 580Mhz
  • 128MB DDR2ram
  • 16MB SPI flash
  • 300Mhz 11n 2T2R WiFi, AP & Station Driver By MTK original
  • all pin-out
  • NGFF M.2 low cost as 0.5 USD

MT7628AN soc brief





  • NGFF Slot B TYPE 2242 B
  • M.2 interface

Hardware intergration

  • NGFF Slot B TYPE 2242 B socket


The M.2 socket WRTnode could ask for WRTnode team to supply by a low cost.
The source of WRTnode series hardware: https://github.com/WRTnode-PCB.

Software & SDK

SDK: https://github.com/WRTnode/openwrt Software:

  • Based on OpenWrt CC 1505
  • Differences for OpenWrt:
    • Defalut network segment of IPv4:
    • Adding wwan as port apcli0, and WRTnode wireless management tools: aps/setwifi/vw/ia
    • Adding MTK WiFi driver: ralink-wifi/ralink-ralink-mt76x8, which have been adapted to OpenWrt CC
    • Adding WRTnode Package feeds
    • Adding SPI-CS1 driver

Wireless networking performance and CPU benchmark

Wireless networking performance

WiFi to RJ45 (LAN) throughput 175.307Mpbs (tested by IxChariot, do did below)

WiFi via nat conversion to RJ45 (WAN) throughput 180.526Mbps

WiFi(LAN) to WiFi(LAN) dual wireless throughput 85.412 Mbps

  • All the test performed in a relatively ideal environment, instead of in the shielding box. WRTnode2P uses the 5DBM FPC external antenna as the retail one:


The distance between ap and sta is about 30cm, two terminal devices is intel i7 windows 10 LTSB and intel i3 windows8.1 enterprise, with 300M USB PC wireless card using rtl-8192.

Delay on WiFi test

WRTnode as the gateway pings the WiFi station.

CPU Benchmark by openssl

Raspberry Pi 1 as reference value, Bench Sum larger the better

The resault of Raspberry Pi 1 and Raspberry Pi 2 is from this page.

Benchmark of inter process communication: delay & performance

WRTnode2P as reference value, Bench Sum larger the better:

Testing method: https://github.com/rigtorp/ipc-bench

MP3 fixed-point encoder test

Because MT7628AN without FPU, we choice a fixed-point MP3 encoder [1]
Test device 1 cubieboard2 Linux 3.4.79 A llwinner A20:
Test device 2 Intel(R) Core(TM) i5-4590 CPU @ 3.30GHz Linux 3.16.0:

Test device 3 WRTnode2P:

Test device 4 WRTnode2R:

Test device 5 WRTnode:

Testing method https://github.com/toots/shine
Encoding the same wav file copy by the 5 devices using the fixed-encoder

Power consuming

Power on, WiFi off: around 3.3v*140mA
Power on, WiFi on, ordinary WiFi throughput: around 3.3v*200mA
Power on, WiFi on, max WiFi throughput: around 3.3v*300mA
