Dotstar Power supply connection

Post by fcardone_ucsd_edu »

Greeting,

Can I power the Dotstar string from either end of the strip?

I want to power a Dotstar string of LEDs and I notice that each end of the strip has extra power supply wires (2 (5V and GND)). I understand that one end is clock and data out and and the other end is clock and data in, but I want to know if the power supply lines on either end are the same.

Thank you,
Frank

You can connect from either end - or both. Providing power at multiple points minimizes any voltage drop along the strip.
