Scheda di sviluppo driver LED RGB WS2812 a 61 bit CJMCU 5050
US$9.99 US$16.99

D: I'm new at this. I guess all 5V and all Gnd connections need to be soldered together. You also have to solder the DO (digital out) connection of a ring to the DI (digital in) of the nextjQuery111308277786757960712_1644798969840 Am I right? Then on the outer ring, Gnd, 5V, and DI get connected to the arduino board. Does all that sound correct?
