What´s more, M66 is currently the smallest quad band GSM/GPRS moduloe in the world … AT the same time it withstands strong frosts, so it´s ready for a wide spectrum of applications. New extraordinary attractive communication module Quectel M66 asks its place maybe even in your application. Does it deserve it? Most probably yes. Besides
GSM/GPRS module Quectel M66 is proud to be small and that it has a Bluetooth Continue Reading
In this tutorial Dave explains what a PCB spark gap is and how it can be a useful zero cost addition to your PCB layout to help prevent ESD damage. He shows how to easily design them into your board and calculate the approximate voltage rating. And of course has some fun applying 5kV to
