Updated Ethernet & WiFi HDD Enclosure Supports 300Mbps with Mediatek MT7620N Processor

I featured an HDD enclosure with WiFi and Ethernet on CNX Software a few months ago, and several people were interested, bought one, and found out it was running OpenWRT, and easily to adapt to your needs, although some people complains it was not able to connect as a client. There’s now a new model, looking similar, by powered by Mediatek MT7620N and supporting 300 Mbps WiFi. While hardware specifications were not published with the first model, the manufacturer decided to release the full specifications for the new model: Processor – Mediatek MT7620N MIPS processor @ 580 MHz System Memory – 64MB DDR1 Storage 16MB SPI flash for firmware SATA interface for 2.5″ HDD up to 2TB (10TB is shown in the description) File systems – FAT32, NTFS, EXT64 (Sic.). Connectivity 2.4GHz WiFi 802.11 a/b/g/n 2×2 up to 300 Mbps with 2 internal antennas Wireless security – WPA-PSK/WPA2-PSK/AES encryption, Intelligent […]

“OpenWRT vs. FCC – Forced Firmware Lockdown?” Video and Presentation Slides

The article about the new FCC rules that may prevent installing OpenWRT, DD-WRT or other third party firmware on Wi-Fi routers and access-point generated quite a buzz at the end of the last month. The “OpenWRT vs. FCC – Forced firmware lockdown?” presentation that started that discussion took place yesterday during BattleMesh V8 event, and the video has now been uploaded to YouTube. Sound quality could be better, and the slides are not shown on the video, but you can download the PDF slides to have an easier time following the presentation. Some keys points include: The requirement to lock firmware are likely to affect all users, not only those living in countries following the FCC regulations. Not only WiFI access points would be affected, but also phones, tablets with CyanogenMod, and more. Vendors will have to “describe in detail how the device is protected from “flashing” and the installation […]

Zidoo X1 Android Media Player (Allwinner H3) Review

In theory, Allwinner H3 is supposed to be a better alternative to Amlogic S805 processor thanks to more powerful Cortex A7 cores, and support for 4K video output and playback, while Amlogic S805 only features four Cortex A5 cores, and support H.265 up to 1080p60 only. Zidoo X1 is one of the TV boxes recently released with H3 processor. If you’ve not read my two previous posts yet, you may want to check out Zidoo X1 specifications, as well as the unboxing and tear-down post. In this post, I’ll focus on testing performance, stability, and video playback capabilities with Kodi. First Boot, Settings and First Impressions I’ve connected an Ethernet cable, an HDMI cable, a USB hard drive, and a USB hub with a USB webcam, an two RF dongles for an air mouse and a wireless gamepad. The box will boot automatically as you connect the power adapter. Boot […]

Espressif is Working on a New Wi-Fi and Bluetooth LE Chip with Hardware SSL Support

Espressif came to fame thanks to its low cost ESP8266 WiFi chip which was originally designed for connected lightbulbs, but soon got used in a variety of applications, and ESP8266 modules must now be the most popular solutions to add WiFi to IoT projects, as long as they are not battery powered. The company has recently announced they were working on a new chip, whose name as yet to be decided, that will support both Wi-Fi and Bluetooth Low Energy. Details are sparse, but we do know the chip will come with 500KB RAM, support hardware SSL and possibly ECDH, deliver 500 DMIPS of performance, and consume 5 uA in deep sleep mode. The company asked for beta testers via their twitter account around 2 weeks ago, so I guess it’s a bit too late to apply. John Lee, working for Espressif, also said the new part should become available […]

MXCHIP EMW3165 is an $8 CE/FCC Certified WiFi Module with an STM32F4 Cortex M4 MCU

A few months ago, Seeed Studio started selling MXCHIP EMW3162 Wi-Fi module with a STM32F2 Cortex M3 MCU clocked at 120Mhz for $9.95. It’s more capable than ESP8266 modules but also around 3 times more expensive. The company has now launched another WiFi module called MXCHIP EMW3165 with an STM32F4 Cortex M4 MCU @ 100 MHz, FCC certification, and listed for $7.95. EMW3165 module specifications: MCU – STMicro STM32F411CE ARM Cortex M4 micro-controller @ 100 MHz with 512KB flash, 128KB RAM, DSP, and FPU Storage – 2MB SPI flash Wi-Fi connectivity 802.11b, 802.11g, 802.11n (single stream) WEP, WPA/WPA2 PSK/Enterprise 16.5dBm@11b; 14.5dBm@11g; 13.5dBm@11n Receiver Sensitivity – 87 dBm Station, Soft AP and Wi-Fi direct Support EasyLink On-board PCB antenna (EMW3165-P model) or IPEX connector for external antenna (EMW3165-E model) CE & FCC compliant Peripherals: 22 GPIOs USART, I2C ADC, DAC Timer/PWM JTAG/SWD debug interface Connectors – 1×20 + 1x 21 half-through […]

Linux Based Zsun WiFi Card Reader Has Been Hacked Too…

A little while ago, I purchased Zsun SD111 W-Fi USB flash drive, and after several tentatives, I finally found a way to access the device’s serial console. Since then the company announced another wireless storage device with Zsun Wi-Fi card reader, and Zoobab decided to try to hack it too. Since the device is pretty hard to open without damaging the enclosure, connecting the serial pin was not really an option, and the first exploit was to input shell commands in the web interface SSID field… For example, entering reboot there, would indeed reboot the device. However, this would still not allow full shell access, and finally after a broader port scan, it was found out that TCP port 11880 was open for telnet daemon. You can then access the shell as root with the same password as SD111: “zsun1188”. For some reasons, telnet can’t work with the device, and […]

IoT Wi-Fi Modules Comparison Table – ESP8266 vs CC3000 vs RN131 vs HDG204

We now have several options to add WiFi to IoT / embedded projects at relatively low cost, and ESP8266 based solutions clearly wins on costs, but are there some advantages to other higher priced modules? To help us find out, Mike Barela has put up a comparison table with some Wi-FI modules based on Espressif ESP8266, Texas Instruments CC3000, Microchip RN131, and H&D Wireless HDG204 processors. Note 1 – Also comes in Arduino Shield size with SD card slot for $39.95 Note 2 & 3 – Adafruit and Sparkfun sell tested units with AT Firmware for $6.95. lower prices are available on eBay, but quality may vary. Note 4 – Currents are probably somewhat higher than stock ESP-12 due to onboard LED and regulator. The comparison is not exhaustive, but it still appears to show ESP8266 solutions support most features than pricer competing modules. There are however case where competing […]
