Wio Link is an ESP8266 Board Designed to Make IoT Projects Easier (Crowdfunding)

There are already plenty of board or modules based on Espressif ESP8266 WiFi SoC, but if you don’t like soldering, or would rather avoid breadboards and some cables for your or your kids’ projects, Wio Link may be interesting, as all you need to is to connect Grove modules required for your applications to get started, and Seeed Studio also took care of the low level software part and a drag-and-drop mobile app is provided, so software programming has been made easy too. Wio Link hardware specifications: SoC – Espressif ESP8266EX Tensila SoC Storage – 4MB flash Connectivity – 802.11b/g/n WiFi, with WEP/TKIP/AES encryption support Expansion – 6x Grove connectors: 3x digital, 1x analog, 1x UART and 1x I2C (3.3V I/Os) Power Supply 5V via micro USB port 3.4 ~ 4.2V via external battery Output DC Current – 1000mA MAX Charge Current: 500mA MAX Dimensions – 55mm*48mm Weight – 26g […]

Quick Start Guide for LinkIt Smart 7688 (Duo) Board

Mediatek Labs has announced LinkIt Smart 7688 development boards powered by Mediatek MT7688 WiSoC earlier today, but I was selected for a close beta several weeks before the launch, and I’ve had time to play a little with the boards, so today I’ll report my experience getting started with LinkIt Smart 7688 amd 7688 Duo by writing a Quick Start Guide showing how to setup the boards, upgrade firmware, access the serial console, run “Blink LED” sample applications with Python and JavaScript, as well as the Arduino IDE, and connect to the Internet. Initial Setup You’ll only need a micro USB cable and a computer with WiFi and USB ports to get started with the board. The green LED (top) for the MCU will turn on immediately, while the red LED (bottom) for WiFI will blink once, and only turn on continuously after 5 seconds, and within 30 seconds after […]

$5 Add-on Board for Raspberry Pi Supports Arduino Shields and Grove Modules (with Caveats)

If you have several Arduino shields, you can use them on your Raspberry Pi B+/ Pi 2 board with Cooking Hacks’ Raspberry Pi to Arduino shields connection bridge supported by arduPi library to control I2C, SPI, GPIO, analog inputs, etc.., and sells for $65 on Amazon. Seeed Studio Grove modules have also become more popular, with several new boards integrating 4-pin Grove connectors such as Beaglebone Green. Raspberry Pi boards also support Grove modules, up to 15 of these!, using Grove Pi+ add-on board which the company sells for around $30. But I’ve just discovered a Raspberry Pi to Arduino Expansion Board V2.0 on DealExtreme, selling for $7.97 that’s allows the latest Raspberry Pi boards with a 40-pin headers to take both Arduino shields and 2 Grove modules. After some investigations, I found out it was made by ITead Studio, where they sell it for $5 + shipping. The Wiki […]
