||Your STEM/STEAM students will be smarter than Arduino!
|This adapter and its companion 17573 PL can help students make sense of coaxial power connectors. Measurements and the metric system in general is a subject in itself. But just getting a STEM/STEAM project to power up reliably is a key to encouraging student success! Many Arduino accessories, surprisingly, are incorrectly sized, often confusing 2.5 mm and 2.1 inside diameters. Sometimes the connection works anyway, but a responsible teacher seriously interested in the future of technology will make sure her students see the differences in good design, engineering, and quality control!|
