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...

VP Process Inc has recently released a new series of Raspberry Pi DIN rail mountable "Hardened" interfaces. The first release is the PI-SPI-DIN-RTC-RS485, which is available in three mounting versions: DIN Rail Clips, DIN Rail Enclosure, and PCB Spacers. The basic specifications...

In order to be able to upload Arduino sketches directly to the ATtiny84 over USB without the need to use a programming device, Shawn Hymel, an electrical engineer at Sparkfun Electronics, had published a guide showing how to install the micronucleus bootloader, which supports virtual USB...

circuitbasics.com has published a series of tutorials on the most popular communication protocols, like UART, I2C, SPI etc. Check them on the links below. Basics of UART Communication Basics of the I2C Communication Protocol Basics of the SPI Communication...

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...

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...

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...

The Tiny Lisp Computer is a self-contained computer programmed in Lisp. Some programming examples are included in the author's website. This article describes a self-contained computer with its own display and keyboard, based on an ATmega328, that you can program in Lisp. You can use...
