AsiaRF AP7620-MPE-1 OpenWrt WiFi Router mini PCIe Card is Made for Computers and Embedded Systems

July 26th, 2016 2 comments

There are many mini PCIe WiFi modules on the market, but what AsiaRF provides with AP7620-MPE-1 is a little different, as it’s a router based on Mediatek MT7620A fitted into a mini PCIe card to be plugged inside a computer or embedded system.

WiFi_mini_PCIe_OpenWrt_RouterAP7620-MPE-1 mini PCIe card specifications:

  • SoC – Mediatek MT7620A MIPS 24KEc CPU @ 580MHz with 2T2R WiFi 802.11 b/g/n (but board only supports 1×1)
  • 802.11ac WiFI Chipset – Mediatek MT7612E AC1200 chipset limited to 433 Mbps
  • System Memory – 64 or 128MB DDR2
  • Storage – 8 or 16MB SPI flash
  • WiFI features
    • Security: 64/128-bit WEP, TKIP, WPA, WPA2, AES; 802.1X Authentication with RADIUS Client
    • Multi-mode support: Access Point/Client mode
    • Support Multiple SSIDs
  • mini PCIe interface with USB2.0 to Ethernet, UART, 8 GPIOs, 1.5V, 3.3V and ground
  • Dimensions – 60 x 41.5 mm (bigger than standard mini card: 50.95 x 30 mm)

The card is seen as a USB 2.0 to Ethernet dongle from the system, with the dongle connected to a router. The reason why the AC1200 chipset is limited to 433 Mbps is because of the USB 2.0 interface in the mini PCIe card itself limited to 480 Mbps.

The company also told me there will be three versions of firmware SDK for this router:

  • Mediatek official SDK
  • Mediatek OpenWrt SDK with Mediatek WiFi driver
  • OpenWrt.org SDK with “public” WiFi driver (most of time uses less power)

The company does not have an habit of release firmware and documentation publicly, so you’ll probably get them after you purchase the card. In case you wonder why you’d ever need such mini PCIe card the company claims “it is ideal for multi-purpose installations for sharing wireless connections”.

The first engineering samples have just been produced. Price will be around $20 per unit, with discount in larger quantities. You can find some more technical details on the product page.

Imagination Solution to FCC Rules for WiFi Routers: Run OpenWrt / DD-WRT and the WiFi Driver in Separate Virtual Machines

June 10th, 2016 9 comments

About a year ago, discussions started about new rules from the FCC that could prevent routers from installing open source third party operating systems such as OpenWrt or DDWRT. Despite the FCC assurance that the rules were meant to prevent some users from illegally tweaking the RF settings, and that it would not have to impact installing of open source alternatives, the reality is that companies such as TP-Link ended up locking their routers up due to the new rules, while Linksys would only ensure OpenWrt/ DD-WRT compatibility on some of their routers, but not all. Companies are probably doing that due to the extra work that would be required to separate the RF settings which need to be locked, and the rest of the firmware. But Imagination Technology’s prpl security group has a solution for their MIPS Warrior P-Class processors using hardware virtualization.

OpenWrt_Virtualization_Block_Diagram

In order to show the concept works, they’ve developed the solution on an evaluation board based on Baikal T1 dual core MIPS P5600 communication processor, and using a Realtek RTL8192 WiFi adapter and the Ethernet port (WAN) for communications. The serial port was used for debugging Linux.

One the software side, they run an hypervisor, and three virtual machines (VM) leveraging the processor hardware capabilities:

  • Open source L4Re hypervisor comprised of an L4 microkernel that can run trusted native applications and act as a trusted hypervisor for operating systems.
  • Open VM for OpenWrt running OpenWrt and providing the main interface to the router facilities
  • Isolated VM for the Wi-Fi driver without direct access to the driver from other VMs, except through the virtual network connection using ports 85 for http, 449 for https or 29 for ssh. That’s the important part to comply with the FCC rules.
  • Dedicated VM for third party applications acting as a sandbox for running third party applications that provide additional functionality such as home automation apps.

Here’s the demo.

Of course, this will not solve the issues for existing cheap routers, but this could be a solution for future not-so-low-end WiFi routers.

VoCore2 WiFi IoT Module Features Mediatek MT7628AN Processor

May 11th, 2016 7 comments

When Vocore WiFi module launched in 2014 on Indiegogo, it quickly became popular as at the time it was hard to find cost effective and small WiFi modules with GPIOs, and its compact Ethernet dock solution was also a hit. The developer has now been working on VoCore2 for several months, and recently announced a beta testing program.

VoCore2Vocore2 preliminary specifications:

  • SoC – Mediatek MT7628AN MIPS processor @ 580 MHz
  • System Memory –  64 or 128 MB DDR2
  • Storage – 16MB NOR FLASH, 1x SDXC via I/O pins
  • Connectivity – WiFi 802.11n 2T2R up to 300 Mbps with either 2 u.FL connector or 1 u.FL connector + on-board chip antenna (Max signal output >19.5dbm peak); 2x 10/100M Ethernet interfaces via I/O pins
  • I/Os – About 30 GPIOs multiplexed with 3x UARTs, 1x I2C, 1x I2S, 1x reference clock, 1x USB 2.0, 1x PCIe 1.1, 1x high speed SPI (40Mbps max), 1x SPI slave, 2x hardware PWM
  • Power Supply – Input: 3.6~6.0V; output: 1.8V, 3.3V.
  • Power Consumption – 74mA @ 5V (wifi on, no data transfer); 233mA @ 5V (max speed cpu and wireless)
  • Dimensions –  25×25 mm

Compare to the first version of VoCore, VoCore2 has a faster processor, more memory, a lower power consumption, a better WiFi signal, and more I/Os. While the software (OpenWrt) will be open source, the hardware won’t be.

VoCore2 is eventually expected to sell for $20 + shipping, For the beta program however, the board is sold for $50 including $20 for DHL shipping, and developers who commit patchsets for VoCore2 to openwrt.org will get a $30 refund. While the hardware is now complete, and OpenWrt runs on the board, there are still many bugs to fix, and the final release is expected in two months time. If you have questions, you can head over VoCore2 forums.

Arduino Yún Shield Adds Ethernet and WiFi to Arduino Boards for $50

May 11th, 2016 1 comment

You can now add WiFi to Arduino for about $3 thanks to ESP8266, and it’s been long possible to add Ethernet with ENC28J60 module now selling for the same $3. Alternatively, if you want some a little more powerful, you could also use IoT modules running OpenWrt such as a $30 WrtNode or $13 LinkIt Smart 7688 both capable of supporting Ethernet with some hacks. But if you’ve been used to Arduino Yun, have a few spare Arduino boards, or simply think the other solutions are just too cheap, Arduino LLC has just launched Arduino/Genuino Yún Shield for $49.90 / 43.90 Euros.Arduino_Yun_Shield Arduino Yún Shield specifications:

  • SoC – Qualcomm Atheros AR9331 MIPS WiSoC @ 400 MHz
  • System Memory – 64 MB DDR2
  • Storage – 16 MB flash
  • Connectivity – 10/100 M and 802.11 b/g/n WiFi
  • USB – 1x USB 2.0 host port
  • Board interfacing – SPI and HW Serial
  • Misc – 5 LEDs (WiFi, Power, Ethernet, Activity and User); Reset shield and config reset buttons
  • Operating Voltage – 3.3V

The shield is compatible with Arduino Uno, Zero, 101, Diecimila, Due, Duemilanove, Leonardo, and Mega2560 boards.

Genuino_Yun_ShieldThe Yún Shield run OpenWrt-Yun and uses the Bridge library just like Arduino Yún board. You can find all details including documentation, hardware design files, and Arduino IDE on Arduino Yún Shield wiki.

LEDE (Linux Embedded Development Environment) Project is a Fork of OpenWrt

May 4th, 2016 9 comments

2016 appears to be the year of splits in open source communities with Kodi losing its main Android developer, LibreELEC being born out of disagreements within OpenELEC community, and now LEDE project, a fork of OpenWrt, has been created because some people are not satisfied with the way the project is managed, and now “includes a significant share of the most active members of the OpenWrt community”.

LEDE_OpenWrt_ForkLEDE, which stands for “Linux Embedded Development Environment” , has three stated goals:

  • Building a great embedded Linux distribution with focus on stability and functionality.
  • Having regular, predictable release cycles coupled with community provided device testing feedback.
  • Establishing transparent decision processes with broad community participation and public meetings.

You can find more on LEDE Project website, and the source code is available on the project’s git server:
