Domino Core Wi-Fi Module Powers an Arduino Yun Compatible Board (Crowdfunding)

The makers of GL.iNet OpenWRT compatible router have decided to build a module and two development boards based on Qualcomm Atheros AR9331 WiSoC. Domino.IO is composed of a Domino Core Wi-Fi module that can be used in your own project, but if also part of Domino Pi, a breadboard-friendly board featuring the module, and Domino Qi mini, a similar board with an Atmel ATMEga32U MCU making it compatible with Arduino Yun board. Domino_BoardsDomino Core specifications:

  • SoC – Qualcomm Atheros AR9331 MIPS processor @ 400MHz with
  • System Memory – 64MB DDR3
  • Storage – 16MB flash
  • Connectivity – 802.11 b/g/n Wi-Fi with u.FL connector
  • I/Os via half through holes – USB 2.0 host/slave, 3x Ethernet, 29 IOs including UART, SPI, I2S, SLIC, etc…
  • Dimensions – 41 x 25 x 3.8 mm

Domino Pi and Qi mini summarized specifications are shown in the table below.

Domino Pi Domino Qi Mini
Wi-Fi Module Domino Core
MCU N/A Atmel ATMega32U4
USB 1x micro USB for power and programming
Header 2x 28-pin headers 2x 22-pin headers
Dimensions 71.12 x 33.02 x 10 mm 55.88 x 33.02 x 10.8 mm

Both boards can be extended with single Ethernet, single USB, 3x USB + micro SD card, and SPI/JTAG add-on boards, with the latter useless not only for debugging, but also for unbricking the board in case you’ve deleted the complete flash.

Domino Pi also compatible with dual Ethernet, I2S audio, and LED add-on board, while Domini Qi mini can be inserted in an Domino Qi baseboard with Arduino compatible headers, a full sized USB port, and Ethernet Port, a micro SD slot, and more.

Domino core comes pre-installed with OpenWRT Linux based operating system, so you can use your favorite programming languages and tools such as  Python, Node.js and npm, PHP, git, Lua, SSH, etc… You can also program the board via Ideino web interface.

The project is now up on Kickstarter, where developers aim to raise at least $30,000. Pledges start at $10 (early bird) with Domino Core, $19 should get you a Domino Pi Basic kit with Ethernet and USB add-on boards, $37 a Domini Qi Mini with the baseboard, and if you want the full package with both boards and all add-on boards, you’ll need to pledge $90. Shipping is $5, and delivery is scheduled for May 2015.  You may also find more information on Domino.IO website.

One of the core OpenWRT developers is on this team so the software should be good.

Looks good but half a watt consumption is quite a bit for an IoT . Others consume much much less with WiFi.

Half a watt for a full-stack Linux router is the smallest power consumption you can get. Everything below is only a small MCU with custom Wi-Fi / IP stack like ESP8266 or TI CC3xxx. You cannot stream audio or video with these, or do any routing because of limited processing power.

Half a watt for Linux wifi is pretty low. GoPro cameras are about 2W with wifi turned on.

But if you are looking for long term IOT battery performance — like years. Wifi is not the right choice. You have to use something like BLE or 802.15.4.

ESP/CC3xxx are in the middle. They don’t run Linux but they will last 6-12 months on a battery with proper programming.

Btw, there’s another campaign running providing exactly IoT-friendly consumption of less than 1mA in always-connected mode (much less than that in sleep + regular wakeup mode): https://www.kickstarter.com/projects/wipy/the-wipy-the-internet-of-things-taken-to-the-next

CNX, maybe to can give it a more detailed review and opinion, because otherwise seeing 3rd absolutely the same AR9331 board in last month is getting old…

Sure, it’s hard to argue with the point that everything but raspberry pi and esp8266 is doomed before even conceived ;-).
