Power constraint is a critical consideration undertaken by designers when selecting a microcontroller for an application — particularly with IoT applications where power plays a vital role. IoT nodes are only useful in the field if they last for years or even a decade on a single battery. The race for lower power devices between…
Electro non mechanical relays characteristics and how-to DIY
With the replacement of vacuum tubes by transistors, it became possible to switch between logic states with a minute amount of power consumption and in a relatively smaller space. This article will focus on logic switching. Not much has changed with electrical switching technologies, although there have been some innovations around various techniques to switch…
