Xiaomi Mi Wi-Fi Mini 802.11ac Router Can Now Be Purchased for $45

Ever since TV boxes with 802.11ac capabilities have been listed, I’ve been looking at purchasing a router with the latest Wi-Fi standard since I would then be able to test 802.11n at 2.4 and 5 GHz, as well as 802.11ac. The vast range of prices got me confused at first, but an article on Connectedly helped me clear things out. One of the most important factor is the different classes of Wi-Fi routers as shown in the table below. The class nomeclature is based on the Wi-Fi standard (AC or N) with a number corresponding to the rounded sum of the maximum throughput at 2.4GHz and 5GHz. Based on this table, and my limited budget ($100), I decided to look for AC1200 or greater routers, and I found one for TP-LINK Archer C7 AC1750 router selling for $100 on Amazon. Awesome! So I went to look on local websites only […]

xWifi Open Source Hardware Wi-Fi Module and Dock for the Internet of Things (Crowdfunding)

For some reasons, Wi-Fi modules are pretty popular this year. After modules such as VoCore, AsiaRF AWM002, and ESP8266, here’s come xWifi. This module is based on Mediatek MT7681 SoC which includes a TCP/IP stack like Espressif ESP8622 or TI CC3300, so it won’t run OpenWRT like VoCore or AsiaRF modules. The module only consumes about 350mW during transfer, it will be open source hardware, and the xWifi module plus a dock with a 10A relay, a humidity and temperature sensor, and a LED will go for as low as $17. xWifi module only specifications: SoC – Mediatek MT7681 802.11 b/g/n SoC with 32-bit RISC CPU. Support for Client/softAP mode. Package size 5×5 mm Storage – 512KB SPI Flash (for firmware) I/Os via headers: UART and SPI interfaces. 5x GPIOs PWM Power – 3.3V, GND Power Consumption – ~70mA @ 5V (during RX active) Dimensions – 14 x 17 mm The […]

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 […]
