Kindly Help

I’m amazed you got 625 pixels out of an UNO. You’ll need to move up to an ARM chip. Choices include ESP32, Teensy (which has a LOT of support), ESP8266 and probably others.

Depending on your project, another option would be to use another UNO/Nano (or whatever AVR board) and use it for a separate set of pixels.

@Manoj_Tripathi the Arduino Uno has 2kb pf SRAM. 625 pixels are using 625*3=1875 bytes. So you are limited by the ram of the Arduino Uno.
So indeed you need to upgrade your mcu.

Don’t know how,but its working
