Raspberry Pi with WS2812b strips

Former Member

Hi

       I am looking for advice regarding feasibility and future errors that I may face for my project. I am trying to control 300 led strips from Adafruit available at http://www.adafruit.com/products/1138

 

These strip require an input at voltage level 5V. I know that I must use a 3.3V to 5V voltage converter  to keep both strips and Pi safe.

 

IS there anything that I should be careful about?

 

Please help.

  • You might damage your 'pi if you connect a 5V signal to your 'pi. Don't connect the "DOUT' signal of your strip to your 'pi.

    You might not reliably transfer data from the PI to the 5V circuits because the "high" of the 'pi is only 3.3V. Officially the required level is "at least 3.5V". But in practise it will work reliably with the 3.3V that the 'pi provides.

     

    So: My suggestion is: Just go ahead and try it.
