Specification: Origin: Mainland China Type: Module Condition: New Model Number: LED Module Lamp bead module Lamp bead power: 3W Lamp bead forward current: 650MA Lamp bead forward voltage: 3.2-3.6V (2.0-2.6V for red/yellow light) Working voltage: DC3.3V-5V Lighting angle: 12-140 degrees Working temperature: -20-60℃ Altitude attenuation: 5000 hours of work, attenuation of 3% Lifespan: about 50000 hours Size: 30mmx22mx8mm/1.18x0.87x0.31inch PCB board hole diameter: 5mm This is a commonly used LED module, which uses 3W warm white LED components. When controlling, you only need to input a high level at the positive pole and signal terminal of the LED module, and the negative pole is grounded, and the LED will automatically light up. This module is compatible with various single-chip control boards, such as for Arduino series single-chip microcomputers, and can be directly connected to the single-chip microcomputer for use. Note: Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-2cm measuring deviation due to manual measurement. Included: 1 x  LED Module
