Running 2 Neopixel Strips in parallel

Post by Brycek »

Hello!

I'm working on a project where I plan to have 2, 2 meter strips that need to act identically. I'm using an Arduino uno, and I'm wondering if it's possible to connect both strips to the same signal pin. Is there even a downside to running them on 2 separate pins?
I'm well aware of power requirements, so that won't be an issue.

Thanks in advance for your replies!

If you want to run two strips with identical patterns, then a 2x fanout from a single pin is certainly possible.
That will save both memory and time compared to programming them as 2 separate strips.

A fanout of 2 or 3 from a single pin is pretty reliable. beyond that, you need to look at buffering the signal.
