by Jason Kelly, CUI Incremental rotary encoders produce two square wave outputs as they rotate, from which the angular displacement and rotational speed can be calculated. These quadrature outputs let the host system determine the direction of rotation. To calculate speed and angular displacement, the encoder’s resolution – equivalent to the angular displacement represented by […]

A comparison of MEMS and electret condenser microphones
By Bruce Rose, Principal Applications Engineer, CUI Inc Many of today’s smart devices such as home digital assistants and IoT sensors are required to “hear” their environment. There is a growing demand for microphones that are not only highly miniaturized, but also robust, easy to design-in, and resistant to nearby acoustic or electrical noise. Fortunately, […]
CUI partners with SnapEDA to offer free PCB footprint files
CUI today announced that it has teamed up with SnapEDA to provide designers with a catalog of free, ready-to-download PCB footprints and symbols for CUI’s range of board mount electromechanical components. Circuit board design has historically been a time-consuming and challenging process due to the variety of product configurations and standards. With this partnership, users will […]
An introduction to audio jack switches and schematics
Standard 2.5 mm or 3.5 mm audio jacks are found in a huge variety of consumer and professional audio products. Widely recognized, easy to use and simple in concept, they can be applied in many ways to enhance convenience for users and manage various features and functions of a product that are not necessarily related […]
