$15 NEXX WT1520 Wi-Fi Router Supports OpenWRT

TP-Link WR703N is a popular low cost router well supported by OpenWRT that costs about $23 shipped. But there’s now a new cheaper router that’s been mentioned in comments on CNX Software a few times, with a different processor, but otherwise similar specs plus an extra Ethernet port. NEXX WT1520 is powered by Mediatek RT5350F, sells for $15 including shipping from sites like Banggood, Aliexpress and eBay, and can run OpenWRT, although it’s not officially supported yet. NEXX WT1520(F/H) specifications: SoC – Mediatek (previously Ralink) RT5350F MIPS processor @ 360MHz System Memory – 32MB RAM Storage – 4MB NAND flash Connectivity: Wi-Fi 802.11b/g/n up to 150 Mbps with built-in PIFA antenna 2x 10/100M Ethernet (LAN and WAN) USB – 1x USB 2.0 host port, 1x micro USB port for power Misc – Status LED, reset pinhole, power button Power – 5V via micro USB port Dimensions –  63 x 43 […]

Zsun SD111 Is Now “Officially” an Hackable Wireless Flash Drive

Zsun SD11x are Wi-Fi flash drives for 8 to 128 GB eMMC, alternative to Sandisk or Kingston. Yesterday, I soldered the UART pins to Zsun SD111 (8GB) flash drive to access the serial console, but I did not manage to enter the terminal as it was password-protected. I posted my results anyway, as I was convinced I would get some clever ideas from my readers, some of which appeared to be a little time consuming, but Zoobab offered a simple solution that consisted in changing the boot parameters, by replacing /sbin/init by /bin/sh. The first step is to interrupt the boot by pressing space or another key, in order to access U-boot. Now we can check the U-boot environment ar7240> printenv bootargs=console=ttyS0,115200 root=31:02 rootfstype=jffs2 rw init=/sbin/init mtdparts=ar7240-nor0:64k(u-boot),64k(u-boot-env),6720k(rootfs),1216k(uImage),64k(NVRAM),64k(ART) bootcmd=bootm 0x9f6B0000 bootdelay=4 baudrate=115200 ethaddr=0x00:0xaa:0xbb:0xcc:0xdd:0xee ipaddr=10.168.168.1 serverip=10.168.168.10 stdin=serial stdout=serial stderr=serial ethact=eth0 Environment size: 361/65532 bytes Let’s keep everything the same, except the init, […]

Zsun SD111 Wi-Fi Flash Drive Hacking Tentative

Two days ago, I reviewed Zsun SD111 a 8GB Wi-Fi flash drive based on Atheros AR9331, and I discovered the telnet port was open, but I could not access it because none of the standard username and password combinations (root/root, admin/admin, root/admin, etc…) would work, which is actually a good thing. However, as I opened the stick, the serial pins were clearly marked, so today I’ve soldered some Dupont wires to access the serial console. In order to open the stick, you need a rigid sharp object to push the top cover via the neck strap hole, as shown below, and another tool (mine looks similar to a scalpel) to help popping the cover up. Then I connected the three wires to a USB to TLL debug board, connected it to my PC, started minicom (115200 8N1), and pressed the power button. I could see U-Boot 1.1.4 message, so it […]

$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 […]

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 […]

The World’s Cheapest Linux Computer? Pogoplug Mobile Now Sells for $7

Somebody asked “Anyone knows a computer cheaper than a Raspberry Pi with a network interface?” on Google+ mini PCs community. Some OpenWRT routers such as TPLink WR703N selling for about $20, or the VoCore Wi-Fi module selling for about the same price (Wi-Fi only) were parts of the answers, and I also mentioned some HDMI TV dongles that now sell for around $35, which is still a little cheaper than the Raspberry Pi model B when one considers shipping. But I found the answer by dhead666 particularly interesting: Pogoplug Mobile goes for 7$ on Amazon and that includes psu and network cable. It run Linux great (I’m using Arch) but you will want to have a ttl-usb cable and soldering iron available in case you manage to mess u-boot (go to the doozan’s forums for more info about the u-boot). Let’s have a look. Pogoplug Mobile is not a new […]

How to Open Tronsmart Vega S89 (Elite) and Access the Serial Console

Tronsmart Vega S89 (Elite) is an Android TV based on Amlogic S802 quad core ARM Cortex A9 processor @ 2GHz, and is one of the fastest Chinese ARM box on the device, at least until Rockchip RK3288 and AllWinner A80 devices come to market. In my unboxing post, I mentioned the UART pins were available, and sometimes in March Amlogic released U-boot and Linux source code for M802/S808, so it’s likely some developers will play around, and eventually run Linux (Ubuntu, Debian, …) on the platform. So today, I’ve done some preliminary work by connecting a USB to serial debug board to my device. The steps to follow are straightforward, and should work on Beelink M8/S82, Jesurun S82, MBOX-S82, IdeaStar S82, etc… which are basically the same box with different names. Before accessing the serial port, we’ll need to open the box. Start by removing the 3 sticky pads at […]

AMLogic S802 TV Boxes Board Pictures

AMLogic S802 Android TV Boxes are currently available for pre-order, and are expected to ship by the end of the month. Last time I wrote Tronsmort Vega S89 and Eny ES8 featuring the latest quad core SoC from AMLogic. Geekbuying currently has test samples for both Vega S89 and M8 (similar to ES8), has open them, and taken some pictures of the boards. The good news, if you want to tinker, is that both of them appear to give relatively access to the UART port. Tronsmart Vega S89 Board There are two models: Vega S89 and Vega S89 Elite. The former is the high-end version with dual band Wi-Fi (2.4/5.0GHz) and 16 GB flash, and the latter only supports 2.4 GHz Wi-Fi and comes with 8GB flash. Price: $120 and $105. The serial port appears to be on the left side of the board (TBC), just above the two USB […]
