Dotstar 128 LED Bar - Basic Circuit

by latkinso42 on Mon Sep 17, 2018 3:09 pm

Hi,

I have recently purchased the Dotstar 128 LED Bar. I understand that its not a traditional strip and was looking for a guide or example circuit to incorporate it to both a Raspberry Pi and then an Arduino. There are lots of references to similar led strip, but as to always leave enough doubt (with all the variations) about how it should be worked into a circuit. Does any one have a basic circuit diagram for this specific Dotstar 128 LED Bar? - Thanks!

Connections are the same as for any Dotstar confuiguration: GND, +5v, Clock and Data: https://learn.adafruit.com/adafruit-dot ... s?view=all
The only thing to watch out for are the power requirements and heat limitations as noted in the product description:

https://www.adafruit.com/product/3776
. . . you could turn on all the LEDs on at full brightness and draw about 6 Amps but you'll overheat and damage the LEDs. So instead, keep your brightness at 50% or don't light up to many LEDs. Keep the power usage at under 15W (3A @ 5V)
