Black Swift is a Tiny OpenWRT Wi-Fi Board Powered by Atheros AR9331 (Crowdfunding)

In case you thought there were not enough Wi-Fi board in the market already, here’s another one with Black Swift. The board runs OpenWRT, is a little larger than Vocore, and quite smaller than WRTnode, is powered by Atheros AR9331, provides access to I/Os via headers, and comes with two micro USB ports which should make it easy to use, and allow some interesting applications with USB devices. Black Swift specifications: SoC – Qualcomm Atheros AR9331 32-bit MIPS 24K CPU core @ 400 MHz, or 200 MHz in energy-saving mode selectable by software System Memory – 64 MB DDR2 SDRAM Storage – 16 MB NOR flash Connectivity – 802.11 b/g/n Wi-Fi (1×1, up to 150 Mbps) with PCB antenna USB – 1 x microUSB for power, 1x microUSB 2.0 port Expansion – Headers for 26x GPIO, 2x Fast Ethernet, SPI, I²C, 1x 16550 UART, 1x USB 2.0 Misc – Factory reset […]

Vonets VM300 Wi-Fi & Ethernet IoT Board with Mediatek MT7620 Runs OpenWRT

Mediatek MT760 is a recent Wi-Fi SoC found in some Nexx WT3020 routers, and WRTnode development board. Both run OpenWRT and costs $17 to $30 depending on the amount of flash, and ports with the former featuring two Ethernet ports, and the latter access to GPIOs. You could probably open the case of the Nexx routers and solder some wires to get access to GPIO, and you can hack an Ethernet cable for WRTnode, but another options could be Vonets WM300 kit that includes a board with Wi-Fi and Ethernet, a cable for USB / Ethernet connection, headers for GPIOs, and two external antennas for less than $30. An OpenWRT SDK is also provided for the kit. Specifications listed for VM300 board: Processor – Mediatek MT7260N MIPS processor @ 580MHz Storage – 4MB SPI Flash (option: 8MB/16MB) for firmware System Memory – 32MB or 64MB SDRAM Connectivity Wi-Fi Single band […]

Zero+ IoT Wi-Fi Board is Programmable with Lisp (Crowdfunding)

There have been so many low cost Wi-Fi modules and boards with GPIO headers announced this year, especially on crowdfunding sites, and from the hardware point of view, Zero+ (Zero Plus) board looks very much like many other Ralink RT5350 boards such as Vocore or AsiaRF AWM002, but what makes it different is that it can be programmed with Lisp from a web-based IDE. But let’s go through Zero+ board specifications first: SoC – Ralink/Mediatek RT5350 MIPS processor @ 360MHz with dual band 802.11n Wi-Fi with data Rate up to 150Mbps System Memory – 32 MB RAM Storage – 8MB to 16 MB SPI Flash (for firmware) Expansions Headers – 2x headers with access to I2C, SPI, USB, 2x UART, JTAG, and 14x GPIOs USB – 1x USB host port, 1x micro USB for power Misc – 2x buttons Dimensions – 36 x 25mm (possibly module dimensions only, not full board). I’m […]

Getting Started with WRTnode OpenWRT Development Board

Seeed Studio sent me two nice little boards that can be used for IoT development: WRTNode and LinkIt ONE. Today, I’ll show pictures of WRTNode and accessories, and go through the “starting guide“, and will test LinkIt ONE board a few days later. WRTnode Unboxing I’ve received WRTnode by Fedex, and the board is stored in a plastic box. Inside the box, you’ll find the board, a “special” USB used to power the board and as an OTG adapter, a piece of paper with useful links (Wiki), and some WRTnode stickers. Any micro USB to USB cable can be used to power the board, but this cable is useless to connect USB devices such as flash drives, webcams (OpenCV is supported), Bluetooth dongles, and so on. You could even connect a USB hub to connect multiple USB devices as shown below. I’ve also taken a picture of both sides of […]

$25 GL.iNet 6416A is an Hackable OpenWRT Router with Easy UART and GPIO Access

There are plenty of low cost routers supporting OpenWRT, but GL.iNet 6416A has several advantages compared to devices like TP-Link WR703N. Both are based on Atheros AR9931, but GL.iNet router has more memory and storage (64MB RAM + 16MB Flash vs 32MB RAM + 4MB Flash), two Ethernet ports instead of just one, and 6 GPIOs, the serial pins, and power signals (5V, 3.3V and GND) are all easily accessible via though holes or headers. Gl.iNet 6416A can be purchased for about $25 on DealExtreme or Amazon US, and it used to be listed on eBay, but is now out of stock. Gl/iNET 6416A specifications: Wi-Fi SoC – Atheros AR9331 MIPS processor @ 400 MHz System Memory – 64MB RAM Storage – 16MB Flash Connectivity – 2x 10/100 Mbit Ethernet ports, 802.11 b/g/n Wi-FI up to 150Mbps USB – 1x USB 2.0 port, 1x micro USB port for power Debugging […]

WRTNode is a Hacker-Friendly Open Source Hardware OpenWRT Wi-Fi Module Selling for $25

There are now some tiny and low cost ($15 to $20) Wi-Fi modules supporting OpenWRT such as VoCore and AsiaRF AWM002. However due to their small size they may not be that hacker’s friendly as they can’t have 2.54mm headers due to heir small size, and I’ve recently received AsiaRF AWM002 only to find out it not only needs 3.3V supply voltage, but also 1.8V and 1.2V. So I’d need to make my own power circuit with the required LDOs, or purchase a $20 base board to use the module. Here comes WRTnode another larger Wi-Fi module but with more usable 2.54mm headers, and based on the more powerful Mediatek MT7620N processor @ 600MHz. WRTnode hardware specifications: Processor – Mediatek MT7620N 600MHz MIPS CPU (MIPS24KEc) System Memory – 64MB DDR2 Storage – 16MB SPI flash Connectivity – Wi-Fi 2T2R 802.11n 2.4 GHz up to 300Mbps Expansion Headers – 2x with […]

Kankun KK-SP3 Wi-Fi Smart Socket Hacked, Based on Atheros AR9331, Running OpenWRT

Kankun KK-SP3 is a $20 Wi-Fi smart socket that can be controlled via iOS and Android app. But one person created a Kankun community on Google+ to try to hack the device and control it from a PC, or from outside the home network for example. Up to now, the device has been opened, found to run OpenWRT, and one the member wrote a Windows app to control the socket from a PC. It is a basic smart socket, without power monitoring capabilities, and unless you start hacking the hardware, all you can do is basically turn it on and off. The device is based on Qualcomm Atheros AR9931, found in many low cost routers supporting OpenWRT, and the socket indeed runs OpenWRT, which you can access via SSH or Telnet (username/password: root/admin). There’s 32MB RAM (Winbond W9425G6JH), and a 10A OMRON relay. The smart socket actually communicates with the […]
