Zsun Wifi Card Reader Adds up to 64GB to Your Smartphone

I’ve previously covered Zsun SD11x USB flash drives with 8 to 128 GB internal flash, a battery, and Wi-Fi connectivity in order to easily add storage to devices without micro SD slots. The company has now launched a new Wi-Fi card reader to do the same, but with your own micro SD card instead allowing up to 64GB extra storage, and easy replacement. Zsun card reader specifications: SoC – Qualcomm Atheros AR9331 WiSoC System Memory – 256 Mbit RAM (32 MB) Storage – Internal flash for firmware (capacity TBD), micro SD slot up to 64GB Connectivity – 802.11 b/g/n Wi-Fi @ 150 Mbps USB – 1x USB 2.0 port for power and use as standard USB card reader Dimensions – 33 x 30 x 13 mm There’s no battery, so you’d have to connect the dongle to a power bank, PC, car charger etc.. to power it. If you connect […]

Freetronics Introduces an Arduino Shield for ESP8266 ESP-01 Wi-Fi Module

ESP8622 has drastically brought down the price of adding Wi-Fi to MCU boards such as Arduino UNO,  but you need to add some cables, and take care of 3.3V to 5V conversion for the UART pins either with a divider made of 2 resistors, or a FET level shifter, and you may not be able to access all I/O of ESP8622 on the popular ESP-01 version of the module. For a neater solution, Freetronics had designed ESP-01 WiFi Module Shield that takes care of all these small issues. Key features of the shield: 3.3V regulator dedicated to the module Logic level shifters on TX/RX lines: compatible with both 3.3V and 5V Arduino models Selectable TX/RX pins: use D0/D1 for hardware serial, or D2 – D7 for software serial CH_PD pin on ESP-01 module pre-biased for correct operation mode Extra ESP-01 pins broken out for your own connections Prototyping area with […]

Review of Zidoo X9 Android Media Player and Video Recorder

Zidoo X9 is quite a unique product on the market, as it’s the only low cost Android platform that I know of that features an HDMI input port with recording capabilities. The hardware is actually based on Kaiboer F5, with some modifications, but the latter focuses on the Chinese market, while Zidoo X9 targets oversea markets with an English firmware by default. I took pictures of Zidoo X9 and its board about a month ago, but a busy schedule and some initial issues with Google Play Store delayed the review. Finally, I’ve completed testing of the device, and ready to share my findings about performance, stability, and features in this review. OTA Firmware Update I’ve had to go through two firmware updates before carrying on with the review, and this part is working great, and they even include a detailed changelog with each release, which they also publish on their […]

Variscite Introduces TI Sitara AM437x SoM with Bluetooth and Wi-Fi

News about Texas Instruments Sitara AM437x processors first surfaced in 2012, before being officially announced last summer. Beside TI’s own development kits, I had not seen any hardware based on the company’s Cortex A9 industrial processor, but Variscite has now unveiled their VAR-SOM-AM43 systems-on-module (SoM) powered by AM4376 , AM4378, or AM4379 SoCs. VAR-SOM-AM43 specifications: SoC – Texas Instruments AM437x single core ARM Cortex A9 processor @ 1.0GHz: AM4376 – No GPU, 4x PRU @ 200 MHz AM4378 – PowerVR SGX530 GPU, 4x PRU @ 200 MHz AM4379 – PowerVR SGX530 GPU, 4x PRU @ 200 MHz, and EtherCAT slave support System Memory – 256MB to 1GB DDR3 Storage – 0 to 512MB SLC NAND flash, and 4GB to 32GB eMMC flash b module. 3x SD/MMC via edge connector Display Interfaces – 24-bit RGB interface up to 1400×1050 resolution; 4/5-wire resistive touch support Connectivity  – 10/100/1000 Mbps Ethernet PHY + […]

Black Swift is a Tiny OpenWRT Wi-Fi Board Powered by Atheros AR9331 (Crowdfunding)

In case you thought there were not enough Wi-Fi board in the market already, here’s another one with Black Swift. The board runs OpenWRT, is a little larger than Vocore, and quite smaller than WRTnode, is powered by Atheros AR9331, provides access to I/Os via headers, and comes with two micro USB ports which should make it easy to use, and allow some interesting applications with USB devices.

Vonets VM300 Wi-Fi & Ethernet IoT Board with Mediatek MT7620 Runs OpenWRT

Mediatek MT760 is a recent Wi-Fi SoC found in some Nexx WT3020 routers, and WRTnode development board. Both run OpenWRT and costs $17 to $30 depending on the amount of flash, and ports with the former featuring two Ethernet ports, and the latter access to GPIOs. You could probably open the case of the Nexx routers and solder some wires to get access to GPIO, and you can hack an Ethernet cable for WRTnode, but another options could be Vonets WM300 kit that includes a board with Wi-Fi and Ethernet, a cable for USB / Ethernet connection, headers for GPIOs, and two external antennas for less than $30. An OpenWRT SDK is also provided for the kit. Specifications listed for VM300 board: Processor – Mediatek MT7260N MIPS processor @ 580MHz Storage – 4MB SPI Flash (option: 8MB/16MB) for firmware System Memory – 32MB or 64MB SDRAM Connectivity Wi-Fi Single band […]
