Is the chip you are looking to prototype with only available in a SMD pinout? This 5050 LED breakout allows for any single 5050 LED chip to be used on a solderless breadboard while taking up the minimum amount of breadboard space possible. This board is compatible with a variety of 5050 LEDs including the APA102 (Dotstar), WS2812 (NeoPixel), SK6812, and numerous conventional LEDs. Just solder your chip to the board and solder on some headers and you are good to go!
