PCF8574 and I/O Bus Expanders

I2C bus and PCF8574

Every so often, a new innovation comes barrelling into the electronics industry and remains useful for decades to come. Almost 40 years after it was introduced, the inter-integrated circuit (I2C) protocol is still a popular low-speed signaling standard for interfacing between host controllers, sensors, slave components, and much more.

Data-Driven Circuit Design

PCB design—particularly designs involving circuits—requires the gathering and analysis of a lot of data.

Component Footprints for Hardware Start-Ups

Creating a custom schematic symbol in a SPICE program.

Creating a hardware start-up is perhaps one of the most challenging tasks an entrepreneur can take on, especially because a hardware start-up requires a vast amount of resources.

PCB design relies on accurate computer models of manufactured components. Since electronic designers need a wide variety of components to design their own devices, component libraries have become an indispensable part of modern CAD.

MSP430: Applications for Low Power MCUs

MSP430 applications on a PCB

When you think of embedded systems, plenty of different applications come to mind. Anything from a programmable microwave to an electronic control unit in an automobile qualifies as an embedded system. Each of these applications needs a different type of processor to provide its functions. For smaller devices like wearables and always-on products, you’ll need […]

PCB Supply Chain Management: Sustainable Guide

A PCB board

A PCB board A reliable PCB supply chain is crucial to ensure the continuous quality of manufactured electronics. Although this is a global issue, the most effective approach is to adopt a personal perspective. The idea of supply chain unification is not applicable today, as virtually every aspect of the supply chain is volatile. However, […]
