Digital Buffer
https://www.electronics-lab.com/article/digital-buffer/
Digital Buffer The digital buffers are used in digital circuits for the amplification of digital signals in order to drive high current loads. Besides current amplification, the digital buffers provide isolation between input and output circuits where output is connected to some high-power load such as a relay, lamp or solenoid, etc. The digital device […]

This is an isolated analog input module that is useful for interfacing Analog signals of various types originated from analog sensors and field devices. The module is very useful for in-process controls, factory automation, industrial applications, etc. Interfacing an analog voltage, an analog sensor to Arduino or other various microcontrollers with optical isolation is very […]
How to isolate RS485 – smaller size and high reliability
https://www.electronics-lab.com/isolate-rs485-smaller-size-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 industrial environments. RS-485 is a common communications port in most industrial applications such as factory automation, […]
SPI Isolation Board
https://www.electronics-lab.com/spi-isolation-board/
The isolated SPI module is designed for applications, where SPI signals need to be transferred over longer distances than usually. It is based on Linear’s LTC6820. The board is designed as two layer stack-up, with GND plane on the bottom layer and signal traces and components at the top layer. Signals and power are supplied […]
Isolated USB-to-UART converter
https://www.electronics-lab.com/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 components into their computers on a daily basis […]
