working at pi3g
In our blog you can expect blog posts about technology and business topics, of course about the Raspberry Pi, but also a wide variety of topics related to Industrie 4.0, IoT, and machine learning - for example about the popular MQTT protocol, Python and Linux embedded development, and much more. Blog entries are not scheduled and not in particular order - the topics are an eclectic mix of what comes up in real life of a company engaged in machine learning & Raspberry Pi embedded adventures.
We are happy to write about special topics that are not so well-documented elsewhere.
If you have any suggestions, we are happy to discuss current topics with you and are always ready to brainstorm workable solutions with you.
