$69 Linux Powered Arduino Yún Board is Designed for the Cloud

Massimo Banzi announced the Arduino Yún, the first of a  family of Wi-Fi products combining Arduino with Linux, at the Maker Faire Bay Area. The company used the name Yún (云), meaning “cloud” in Chinese, as the purpose of this board to allow connection to web services directly from Arduino. Arduino Yun Specifications: MCU – Atmel ATMega32u4 @ 16 MHz (same as the one used in Leonardo board) with 2.5KB SRAM and 32KB flash SoC – Atheros AR9331 MIPS-based Wi-Fi SoC running Linino, Arduino’s own Linux distribution based on OpenWRT. It’s the same chipset as in TP-Link WR703N router. Storage – microSD card slot USB – micro USB connector + full USB host port Connectivity – Ethernet + Wi-Fi 14 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs) Arduino Yún ATMega32u4 can be programmed as a standard Arduino board by plugging it […]

$14 Marstek MPR-N9 WiFi/3G Router with 2,400 mAh Battery

One of my readers (Onebir) brought Poray M3 mini Router to my attention a few days ago, as it just cost $17 at the time (now over $20) and OpenWRT developer Squonk seems very interested about it since it features microSD and SD card slots missing in TL-WR703N. However, the device only has 16 MB memory which makes it somewhat difficult to run OpenWRT, or at least some of its features. But today, I’m not going to talk about this. Mentions of Poray M3 router came in HAME MPR-A1 OpenWRT forum thread, and I discovered a new (to me) type of low cost, small form factor device: portable Wi-Fi/3G routers. Those devices are about the size of android mini-PC and contain the chips to handle Wi-Fi, USB host (for external 3G dongle), and comes with a built-in battery so that you can use them anywhere (beach, mountain, car…), as long […]

TP-Link WR703N – $23 Hackable openWRT Wi-Fi 802.11N Router

TP-Link WR703N is a tiny 802.11N 150 Mbps Wi-Fi router smaller than a credit card (5.7 x 5.7 cm) and 1.8 cm thick based on Atheros AR7240 processor with 4 MB flash and 32 MB RAM. It costs just above $20 US and can be hacked with openWRT. It features one USB host connector that allows you to connect USB devices (USB flash drive, printer…) to it. TL-WR703N Specifications: Atheros AR7240 CPU @ 400Mhz (MIPS24k core) Atheros AR9331 Chipset (integrated wireless) 10/100 Mbit Ethernet port 802.11 b/g/n 150Mbps 3G support via external USB dongle 4 MB flash memory 32 MB RAM USB 2.0 port micro-USB port for power Dimension – 5.7 x 5.7 x 1.8 cm All you need is a USB to TLL board to access the serial console, open the box to access the serial pins (TP_IN and TP_OUT) and follow the instructions on openWRT website to convert […]
