адресуемый WS2812B LED с радиатором (10mm*3mm) 5 штук

Достоинства: высокое качество, smd светодиоды на подложке удобно паять крепить,

Самое главное достоинство адресуемые, никаких резисторов на каждый цвет.

без резистора тоже работает, пишут для того что бы не выжечь первый светодиод, сколько не тестировал без резистора не получилось вывести из строя светодиод, но в проект, установил резистор)
