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 […]

AsiaRF AWM002 Wi-Fi Module and a Tiny IoT Server Kit Get Crowdfunded for $15 and Up

VoCore Wi-Fi module selling for $15 to $20, and it’s corresponding VoCore Dock with Ethernet has been quite popular, and at the time of writing, the project has already received $40,000 in funding with 50 more days to go. But if you’d rather get something for the same price, a few months early, and an already FCC/CE certified and proven module and tiny IoT server, AsiaRF has also launched a crowdfunding campaign for their AWM002 Wi-Fi module running OpenWRT on the same Ralink RT5350 found on the VoCore. as well as AWM002 Tiny Kit which adds Ethernet and USB, and a larger board with easier access to all ports and I/Os. As a reminder, let’s go through AWM002 specifications again: SoC – Mediatek/Ralink RT5350 MIPS 74KEc core @ 360 MHz dual band 802.11n Wi-Fi with data Rate up to 150Mbps, hardware NAT, QoS, TCP/UDP/IP checksum offloading. System Memory – 32 MB Storage […]

Prpl Non-Profit Organization to Work on Linux, Android, and OpenWRT for MIPS based Processors

In what looks like an answer, albeit fairly late, to Linaro, the non-profit organization working on open source software for ARM based SoCs, a consortium of companies composed of Imagination Technologies, Broadcom, Cavium, Lantiq, Qualcomm, Ingenic, and a few others, has funded Prpl (pronounced Purple), “an open-source, community-driven, collaborative, non-profit foundation targeting and supporting the MIPS architecture—and open to others—with a focus on enabling next-generation datacenter-to-device portable software and virtualized architectures”. The Prpl foundation will focus on three key objectives: Portability – To create ISA agnostic software for rapid deployment across multiple architecture Virtualization & security – To enable multi-tenant, secure, software, environments in datacenter, networking & storage, home, mobile and embedded Heterogeneous Computing – To leverage compute resources enabling next generation big data analytics and mining Initially there will PEG (Prpl Engineering Group) to take of the following projects for 4 market segments (datacenter, network & storage, connected consumers, […]

$15 Open Source Hardware VoCore Wi-Fi Module Runs OpenWRT (Crowdfunding)

There are already low cost Wi-Fi modules that can be used for the Internet of Things such as AsiaRF AWM002 and Hi-Link HLK-RM04. However, AsiaRF mainly caters to companies, and the Hi-Link module has a limited memory (16MB), which may or may not be an issue depending on your application. VoCore Wi-Fi module could prove to be an interesting option as it is the same $15 to $20 price range, runs OpenWRT with 32 MB RAM, will be open source hardware, and provides up to 20 GPIOs in a tiny (25x25mm) form factor. VoCore Wi-Fi module specifications: 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 SPI Flash (for firmware) / 16 MB on limited edition Available Signals (Via through holes): 10/100M Ethernet USB UART, I2C, SPI I2S, PCM JTAG Over 20 […]

$15 AsiaRF AWM002 & AWM003 Wi-Fi Modules Run OpenWRT, Expose GPIOs

This week-end I explained how to build a web server that could be used for automation and other Internet of things applications for less than $15 by combining an Arduino Leonardo with ECN18J60 Ethernet module. The hardware itself is cheap, but it may not always be convenient, or cost effective, to wire your house or office with Ethernet cables. One solution is to use Wi-Fi modules such as TI CC3000 evaluation module, an Electric Imp module, or Ariettea G25 + Wi-Fi board, but these usually cost between $30 to $50 in single quantity. AsiaRF AWM002 and AWM003 are low cost 802.11n Wi-Fi modules with access to GPIOs that could be an interesting alternative as they cost $15 + shipping, and even below $10 in quantities. The only difference between the two is that AWM003 supports more RAM (64MB vs 32MB). Here are the specifications for these modules: SoC – Mediatek/Ralink […]

$27 TP-LINK TL-MR10U is an Hackable OpenWRT Wi-Fi Router with a Power Bank

TP-Link WR703N is a cheap 802.11 b/g/n router (you can now get it for about $20) that can easily be hacked to run openWRT and for example, act as an home automation gateway, printer server and more.  But if you need a battery powered router for your application, TP-Link TL-MR10U,  based on similar hardware as TL-703WR, should be a better match as it comes with a 2600 mAh battery, and costs just about $27 on DealExtreme. Here are the specifications of the device: CPU – Atheros AR9331 CPU @ 400Mhz System Memory – 32MB RAM Storage – 4 MB Flash Connectivity: 10/100 Mbit Ethernet port 802.11 b/g/n 150Mbps 3G support via external USB dongle USB – USB 2.0 port + micro-USB port for power Misc – Serial port access Dimensions – 91mm x 43mm x 25.85mm(L x W x H) The device comes with a microUSB cable and a user’s […]

Freescale i.MX6 Based Server Systems – Cornfed CONSERVER and Ventana Network Processing Boards

I usually spend most of my time writing about low cost hardware in this blog, but in this post, I’ll deal with higher-end and more expensive devices based on Freescale i.MX6 with Cornfed CONSERVER Server System and corresponding CONSERVER motherboard, as well as Ventana Network Processing Boards. Cornfed CONSERVER Conserver is a low power high-performance ARM processor server system based on Freescale i.MX6 with 4GB RAM, Gigabit Ethernet, and SATA.
