A new decade of electronics has arrived. Technologies such as SigFox and LoRa are ideal for the expanding Internet of Things, and there are innovative processor architectures such as RISC-V. Developers are expecting to prepare ready to go applications using affordable hardware and software. The modular approach, which is becoming increasingly common, is the quickest way to reach one's goal. But for fine-tuning, know-how on the interaction of individual components remains indispensable. At the same time, a growing number of electronics engineers are taking an interest in marketing privately developed solutions. -- More --
