WS2812b LEDs control

[sibha]

Hello RevPi Community,

I have a short question regarding the controlling of the WS2812b LED strips. I have a RevPi Core along with a RevPi DO, as RevPi doesn't have any GPIO pins, and I would like to ask that whether I would be able to control the LED strips with the RevPi DO. As I have seen that I need 800 KHz datastream for the Adafruit WS2812b LEDs but the maximum I could achieve with the RevPi DO is around 400 Hz.

Does anyone have an answer or a suggestion for me that I could really use. I've tried the videos but not enough luck with them.

Thanks & Regards

Hi sibha, with the DO or DIO you won't be able to transfer a protocol frame. So this won't do with this RGB led setup.
But there is the RevPi Connect that has the Con Bridge. Have a look at the schematic here:
