Getting Started with MediaTek X20 Android Development Board

Thanks to CNX for helping me get a hand on the 96Boards compliant Mediatek X20 board that was generously donated by Seeed Studio. In this article, I will walk through the steps to get the board up and running and also compile Android from the source code. The current Android is version 6. Unboxing the Beast First Boot Up The board boots up from the eMMC, and the first time you boot up you will get Android screen as shown in Figure-9. This is the default Android image from the factory, which surprisingly looks like it was setup for a phone screen mode, which is not sufficient for a HDMI monitor. It would be better to install the images that are made available at Linaro website or build your own. See the other section to flash the board with different images. Switching to Fastboot Mode Flashing image files are done […]

Review of Wio Tracker with GPS, Bluetooth 3.0 and GSM Connectivity

Wio GPS – also called Wio Tracker – is an Arduino compatible board based on Microchip Atmel SAMD21 MCU with GPS, Bluetooth, GSM/GPRS connectivity, as well as several Grove connectors to connect sensors and modules for your IoT project. SeeedStudio sent me a sample for evaluation, so I’ve tested it, and reported my experience below by testing some of the Arduino sketches. Wio Tracker Unboxing All I got in the package was Wio GPS tracker v1.1 board. The top includes the Atmel MCU, an RGB LED, a microphone and 3.5mm AUX jack to make phone calls, a user and power button, a micro USB port for power and programming, a small 2-pin connector for a battery, and 6 Grove connectors for digital, serial, I2C and analog modules. The other side of the board comes with Quectel MC20 module that handles Bluetooth, GPS and GSM, a dual use micro SD card […]

ESP8266, Mongoose OS & Grove Sensors – An Alternative Solution for Hackathons

CNXSoft: This is a guest post by Cesanta If you walked into any Hardware hackathon over the last year, you would see they are about innovation and bringing new ideas to this world and most of them are centered around the connected devices nowadays. However, just walk the floor, talk to the teams and you can quickly see an elephant in the room. The Hackathons are about connected devices, but with the ‘recommended’ and frequently sponsored hardware distributed to the teams such as Intel Galileo, Raspberry Pi, etc…. developers may struggle for a long time to even connect it to the cloud! Not to mention the innovation is usually hindered by a tedious environment setup which takes hours, things to learn about the specific hardware and how it can be programmed using low level languages. So many teams spent most of the time fighting with those issues and oftentimes still […]
