Open Source Hardware boards for NB-IoT technology presented at RuseConf 2019

nbito

RuseConf is part of IT-Tour. Every year IT-Tour organize conferences in Sofia, Plovdiv, Varna, Ruse, Burgas, Veliko Tarnovo. They are all made by volunteers and completely free to participate. The idea is to encourage local IT community to share ideas and interesting talks.

This weekend on 28th of September was RuseConf and Olimex presented there our newest NB-IoT boards.

NB-IoT-DevKit boards will be on our web for sale next week with sale price per one unit EUR 18.00. They employ the NB-IoT technology which uses existing LTE 4G network to implement LPWAN.

The NB-IoT devices use low power and can operate on battery for 10 years if network traffic is less 200 bytes per day (this may seems small but SigFox for instance allow 2 to 140 uploads of 12 bytes messages per day. NB-IoT has no restrictions and limits, but if have to be careful as more traffic means more battery discharge. One GSM LTE base cell can connect up to 100 000 NB-IoT devices at same time ( but of course it no one talk on his GSM phone in this cell range) which beats LoRa gateway maximal theoretical 49 connections. Also the NB-IoT module we use has +20dB more sensitivity so if normally one Base cell can connect to NB-IoT nodes up to 10km this module has 10 time more sensitivity and can connect up to 100 km from the base cell. This of course is marketing claim theoretical claim as explained in the talk but still impressive.

It’s Friday again and time for our Guess What is this Quiz

We just finished the routing of this new board, so the question is Guess what is it?

It uses Quectel EG21-G module which works anywhere in the world covering all GSM standards and frequencies. It also has GNSS build-in.

It also can connect to any network 2G-3G-4G whichever is available (sorry no 5G yet 😉 ).

Once the prototypes are ready and check we are preparing Crowd Supply campaign for it! Hint Fits perfect to LoRa-GATEWAY and allow connection where no wires and optics like mountain hubs, remote areas etc.

You can post here or retweet/share/boost on Twitter/Facebook/Mastodon/Diaspora and in Monday we will let Random.org to decide who will win one of our new eduArdu educational board.

Have a nice weekend!

UODATE 22-04-2019: Random.org selected @netsigi as winner!

 

New A13-SOM-LTE design on GitHub

What you see on the picture above is A13-SOM-LTE shield which enables 100 Mbit 4G Internet access to A13-SOM.

The LTE shield is specially designed for 4G module from partner we work with. This is the first prototype and some tests should be completed but it’s matter of weeks or months these modules to be released. We still have no price on the 4G module as these are very new but we are assured to have them on the very low cost, so with A13-SOM to enable wearable cloud technology.

100Mbit is enough to listen music, watch videos, log large amounts of data to cloud storage.

 

A13-SOM-LTE shield is OSHW, the schematic and CAD files are on GitHub.
