New user here, but going big. I am planning a project running 4 x 7 metre WS2812 B 60/m LED strips, entire project run by a RPi, each strip controlled by a separate power supply and fadecandy. There will be power injection every 2 metres or so. Data will be fed to each 64 IC section.
My question is: In the Adafruit NeoPixel Überguide, a capacitor (1000 µF, 6.3V or higher) across the power connection is recommended at the start of an LED strip. Should I put a capacitor in wherever there is power injection?
I’ve done a number of searches which bring up the use of a capacitor, but haven’t found anything that talks about capacitors and power injection.
