One thing that we can agree on is that QR codes, which originated in Japan, have now reached most of the world, and are used, most probably, way beyond what the inventors at Denso Wave intended—the automotive industry.
We have recently released the RAK12500, a GNSS module featuring the u-blox ZOE-M8Q module, which truly talks to everybody: not only does it work with GPS, GLONASS, BeiDou and QZSS , it works both with Serial and I2C.
Spring launch event has started and it brings you a bunch of new WisBlock modules. We are sure that they will be very helpful in your next IoT adventures.
