could not drive more than 625 pixel LEDs with Arduino UNO
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.
