LED RGB 5 مم 3 ألوان (كاثود مشترك) عبوة من 10

Came with clear pinout info printed on the bag, so I didn’t have to guess which leg was red, green, or blue. The 2.8-3.2V forward voltage on green and blue matched my 3.3V logic perfectly.

The blue channel at 460-465nm is exactly what I needed for a nighttime project, and the common cathode pinout made wiring it into my existing setup a breeze. All ten LEDs lit up evenly on the first try, which is rare for a budget pack.

The red channel sits at 1.9-2.2V while green and blue need more, so I had to adjust my resistor values per colour—good thing the spec sheet was clear. It’s a solid pack for breadboarding, and the 515-520nm green is genuinely bright.
