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 […]

The New Fujitsu ReRam
https://www.electronics-lab.com/new-fujitsu-reram/
Resistive random-access memory (RRAM or ReRAM) is a type of non-volatile (NV) random-access (RAM) computer memory that works by changing the resistance across a dielectric solid-state material often referred to as a memristor. Fujitsu Semiconductor has just launched world’s largest density 4 Mbit ReRAM product for mass production: MB85AS4MT. Partnering with Panasonic Semiconductor Solutions, this […]
Build Your Own I2C Sensor
https://www.electronics-lab.com/build-i2c-sensor/
Since Raspberry Pi doesn’t have a built-in ADC (Analog to Digital converter) to read the voltage off from most of sensors, the best solution is to add I2C ADC chips and modules to your project. Paweł Spychalski faced this problem while building his own weather station that is based on Raspberry Pi. It collects various […]
Introduction to I²C and SPI protocols
https://www.electronics-lab.com/introduction-i%c2%b2c-spi-protocols/
byteparadigm.com has a nice introductory article on I2C and SPI protocols: Today, at the low end of the communication protocols, we find I²C (for ‘Inter-Integrated Circuit’, protocol) and SPI (for ‘Serial Peripheral Interface’). Both protocols are well-suited for communications between integrated circuits, for slow communication with on-board peripherals. At the roots of these two popular […]
