P34-RGB05P02N3P1IMA03-CC

## Description

The P34-RGB05P02N3P1IMA03-CC is an addressable RGB LED from Shenzhen H-Great Optoelectronic in a 3.4 x 3.3 x 1.9 mm PLCC-6 SMD package. It integrates a constant-current driver IC with 8-bit PWM control (256 grayscale levels per channel) and a single-wire serial data interface running at 800 Kbps. The device supports daisy-chain cascading via DIN/DOUT for LED strip and matrix applications.
