Open-Source NB-IoT Shield for Arduino

This completely open-source LTE shield uses the latest and greatest CAT-M NB-IoT technology optimized for low-power IoT devices! by Timothy Woo @ hackster.io:

With the emergence of low-power IoT devices with cellular connectivity and the phase-out of 2G (with only T-mobile supporting 2G/GSM until 2020), everything is moving toward LTE and this has left many people scrambling to find better solutions. However, this has also left many hobbyists facepalming with legacy 2G technology like the SIM800-series modules from SIMCOM. Although these 2G and 3G modules are a great starting point, it’s time to move forward and SIMCOM recently announced their new SIM7000A LTE CAT-M module at a developer’s conference. How exciting! 🙂

Open Source Ethernet Audio Broadcaster

Luca Pascarella @ open-electronics.org presents how to setup their open source ethernet broadcaster. He writes:

Recently, we have presented an Ethernet audio streaming unit. In particular, we have shown how to configure the boards to work with other similar devices or with VLC Media Player, setting up a point-to-point or a broadcast streaming in all possible configurations. Also in the first episode, we analyzed the electrical circuit and the components choice. Now it is time to describe the board software advanced options and how to update firmware via Internet or manually.

IoT Protocols for the Electronics Designer

Here is an interesting article from autodesk.com about IoT for the Electronics Designer. Learn how to choose the Right Protocol for Your First Project.

The Internet of Things (IoT) is connecting our world together more intimately than ever. It’s also adding a whole new level of complexity and confusion on the shoulders of the electronic designer. The biggest problem is the overwhelming amount of choices and considerations that have to be made for an IoT project. Which protocol is the best? Will my chosen protocol be irrelevant a year from now? Do I have the time to design RF and an antenna? In this blog, we’ll be focusing on the topic of protocols, how they fit into the networking stack, and how you can use modules to make easy work for your first IoT project.

Alongside the processor and the memory at the front side of the board, you will find a 40-pin GPIO header, a DSI display slot, an Antenna connector, a CSI camera slot, a USB OTG adapter, a USB2.0 port, a microphone and a DC power jack. On the rear side, there is an antenna, a PMIC AXP223, a battery interface and a microSD card slot.

Front and rear sides

This board is oriented for IoT applications in general. Since there is no HDMI interface, M2 Magic is suitable for headless use, or you can use the MIPI DSI display interface to connect a screen. It also doesn’t have an Ethernet interface, so you will have to use WiFi and Bluetooth connectivity.

The board will run Tina IoT Linux, which is a lightweight Linux distribution optimized for Allwinner R-Series processor.

Tina IoT Linux

Both A33 and R16 versions are available in the market. A33 version is for $23, while R16 is for $28. You can get it from any global distributor or cooperative partner of Banana Pi products. Finally, you can reach more information and data at the official wiki.

ESP8266 based e-paper WiFi weather station

Erich Styger documented his experience building Daniel Eichhorn’s e-paper weather station with a custom enclosure:

Using e-paper for a weather station is an ideal solution, as the data does not need to be updated often. By default, the station reaches out every 20 minutes for new data over WiFi and then updates the display. Daniel Eichhorn already has published kits for OLED (see “WiFi OLED Mini Weather Station with ESP8266“) and touch display (see “WiFi TFT Touch LCD Weather Station with ESP8266“). I like them both, but especially the TFT one is very power-hungry and not really designed to work from batteries. What I would like is a station which can run for weeks.
