Aluminum alloys can contain Chromium
To put it simply we are a small company and do not have the resources to test every single part, so we list every thing as hazardous. Please recycle all electronic parts responsibly and under no circumstance eat, drink or smoke these parts and wash your hands after touching!
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!
