DigiKey is offering several of their TechZone electronics magazines available free online. One publication which looks interesting is the Microcontroller Solutions Magazine. Its not a glorified advertisement or catalog, but contains articles on both basic and advanced MCU topics such as “Understanding Microcontroller Performance Analysis Techniques” and “Developing Next-Generation Human Interfaces Using Capacitive and Infrared Proximity Sensing” found in the current issue.
You can check out this publication and others available for e-subscription at Digikey TechZone.
Authors take note, as Digikey TechZone is also accepting article submissions. You can get their Media Kit here.
