3 cent PMS150C MCU drive 300 WS2812B LED’s
Driving 300 WS2812B RGB LED’s with “the 3 cent microcontroller” – the Padauk PMS150C. The 3 cent Padauk PMS150C is.. Interesting to say the least. First of all there’s a lot this little MCU doesn’t do. It doesn’t have a lot of code space (1K Word), it doesn’t have a lot...
