This is SK6812IC SMD3535 RGB programmable led strip
We made the new strip one meter length considering voltage drop
2X0.5M soldered together, it makes the led's 4.9mm centres so that solder gap would be ok as you would not notice it.
The width is 7mm, because my client used it in a small model (Miniature Ferris Wheel Ride)

He is very Professional guy and serious about this model

Lastly, we put the pads on the rear on the PCB and will have more space on the front for the LED and Capacitor
