How to isolate RS485 – smaller size and high reliability

Galvanic isolation for the RS-485port. RS-485 has been the industry’s most used wired communications interface for more than decades. Balanced differential signaling of RS-485 allows for rejection of common mode noise and facilitates communications over long distances in noisy...

Isolated USB-to-UART converter

Jacob Beningo shows how to build an isolated USB to UART converter using Sparkfun's modules. A simple isolation circuit that costs only a few dollars could have been used to protect the USB port on the computer. Embedded system developers get used to plugging strange hardware and...
