I would rather buy some APA102 strips now, use my RPi4 to drive them and use the existing power supply from the insanelight package to power the strips. I guess it has 50W. What would you recommend to buy? 30pcs/m or 60pcs/m strips?
As far as I read the LEDs do have a power consumption of 0.2W per piece, so the power supply should be fine for both in my setup with currently 94 LEDs (with 30pcs/m) even if I would double the number of LEDs.
Question already answered: LED power calculator - LED-Leistungsrechner does not allow for the 60pcs/m setup in my case, if I want to use the old power supply.
How can I make the connections longer? My RPi will not be behind the TV screen, hence I need to make the connection for power and controller wire longer.
