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 […]

Nadhat is an Add-on Board for Raspberry Pi Boards with 2G GSM/GPRS Support

Making Raspberry Pi HATs for fun seems to have become a popular hobby, as after checking out Leon Anavi’s Infrared pHAT a little while ago, I’ve just come across Nadhat add-on board with GSM/GPRS and Bluetooth 3.0 made by Frederic Pierson in his spare time. Nad stands for “Network Access Device”, and the device comes with the following specifications: SIM800C module with 2G GSM/GPRS support, and Bluetooth 3.0 + EDR (but Bluetooth is not mentioned by the developer, so it may not work right now) SIM card slot + connector for GSM antenna CR1225 cell battery slot for RTC 40-pin header provided, but not soldered Dimensions – 65 x30 mm, compatible with Raspberry Pi Zero He explains that he made the board himself and the PCBs “are leaded reflow processed and do not follow regulations in Europe”. You’ll also have to provide your own GSM antenna and CR1225 battery. He’s […]

RDA Micro RDA8810 Android SDK with Linux & U-boot Source Code for Orange Pi 2G IoT Board Released

Orange Pi 2G IoT board was released a couple of weeks ago, shortly followed by Android and Ubuntu images, but since it was not based on Allwinner, but an RDA Micro 8810PL processor, we did not have any source code so far, which can be a real problem for a development board… Shenzhen Xunlong has now managed to upload a 6.7GB Android SDK to MEGA, with the link published via Orange Pi Resources page. MEGA has a download limit which depends on how much traffic they get at the time, and after 5.3 GB download, I was asked to register for a PRO account, or wait for four hours before resuming the download. If you want to avoid this limit for any large MEGA download, you can run megadl instead. That’s what I did in Ubuntu 16.04 (remember to escape any special characters with \):

sudo apt install megatools
megadl https://mega.nz/#F\!59EVmKAZ\!5FdBb2dQIMcxgY2h16nGPg

1 2	sudo apt install megatools megadl https://mega.nz/#F\!59EVmKAZ\!5FdBb2dQIMcxgY2h16nGPg

Once the download is […]

OpenCellular is Facebook’s (soon to be) Open Source Wireless Access Platform

A few months after Canonical and Lime Micro LimeSDR open source software defined radio aiming to be used as a development platform, but also as the base for low cost cellular or other wireless base stations, Facebook has announced their own open source wireless access platform with OpenCellular project whose goal is to lower the cost of Internet connectivity in remote areas where the infrastructure does not exist. This is how Marc Zuckerberg summarizes the project: We designed OpenCellular as an open system so anyone — from telecom operators to researchers to entrepreneurs — can build and operate wireless networks in remote places. It’s about the size of a shoe box and can support up to 1,500 people from as far as 10 kilometers away. Along with our solar-powered aircraft Aquila and high-bandwidth laser beams, OpenCellular is the next step on our journey to provide better, more affordable connectivity to […]
