Q:
Is this the CJMCU-2812B or CJMCU-2812? Pictures indicate that it is the “B” version but dimensions indicate it IS NOT “B”

These are WS2812B 5050 RGB LEDs, sum 61pcs, on 5 rings. Sizes of the rings I have received: 24pcs LED: outer diameter is 86mm, inner diameter is 72mm. 16pcs LED: outer diameter is 68mm, inner diameter is 54mm. 12pcs LED: outer diameter is 50mm, inner diameter is 35mm. 8pcs LED: outer diameter is 32mm, inner diameter is 18mm. 1pcs LED: outer diameter is 14mm. Works well.

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 nextjQuery1113019821581354292372_1644801580205 Am I right? Then on the outer ring, Gnd, 5V, and DI get connected to the arduino board. Does all that sound correct?
