Large LED stripe with 1500 WS2812B

[BrunoMerz]

I plan to drive 1500 WS2812B LEDs with either ESP8266 or ESP32. I know that power supply is not easy but I'm sure I get it working. But I'm not sure wether ESP is fast enough and especially if Adafruit Neopixel library can drive so many LEDs. Up to now I implemented one project with Wemos D1 mini V3.0 and 175 WS2812B without any problem.
Any hints would be very helpful.
Thanks

Speed isn't an issue as long as it's capable of generating the data signal. More pixels just means it take longer to update them, the "speed" of the signal is fixed. Memory is a bigger concern and 1500 pixels will need about 4.5K. I can't find a memory size for the ESP8266 but the ESP32 has 520K which, clearly, is plenty. Power will be your biggest requirement.

If you haven't yet, see https://learn.adafruit.com/adafruit-neopixel-uberguide for advice on powering loads of pixels.

Processor speed is generally not a factor when communicating with the pixels since the WS2812 protocol has a fixed frequency. So the time to update 1500 pixels is about the same regardless of your processor speed. https://learn.adafruit.com/adafruit-neo ... aq-2894689

For higher speeds, you might consider a different type of pixels or a parallel strip DMA solution: https://learn.adafruit.com/adafruit-neo ... aq-2894690
