Introduction:IoT is expected to grow to the rate of $772.5 spent by 2018, with a total increase of 14.6% from the amount spent in 2017. By 2020, annual revenues could exceed $450 for IoT vendors and these figures are expected to keep on growing over time. Today’s market demands implementation of IoT in nearly all electronic products. IoT is helping innovators to invent new tech devices all aiming to appeal to the consumer; the possibilities with IoT are limitless. IoT devices are not simple; they are a combination of distinct components, interfaces, PCBs and electrical circuits each with a unique design and layout and equal challenges. For modern IoT designs, we require a PCB design environment with advanced functionality. In this article we will discuss the various aspects and critical points to consider when designing PCBs for the Internet of Things.1: IoT DomainsAnalog & Digital: Analog-to-digital converters (ADC) are used in IoT designing to process, store and transmit analog sig...
