The LIBRARY basement part 9


The very first color e-Paper roll-out in the food retail sector encompassing all store areas.


Among all the platforms, LoRaWAN platforms held the highest market share of over 50% in 2018 as they use unlicensed spectrum and are best suited for applications that generate low traffic and require low-cost sensors.



This week Electric Dollar Store opened its doors, selling interchangeable postage-stamp sized I2C-based modules for prices between $1.00 and $1.80. The modules include lights, buzzers, counters and sensors — the range is aimed at electronic makers. These aren’t manufacturing rejects shipping from Asia — they’re assembled, tested and shipped from a small farming town in California, where winter labor is cheap.

All the code for the project is BSD licensed.

The project is a spin-off from the popular open-source I2CDriver hardware debugger.
