Boardoza OPT4048 Color Sensor Breakout Board

The Boardoza OPT4048 Color Sensor Breakout Board is a high-precision optical sensing solution designed for accurate ambient light and color measurement. Based on the Texas Instruments OPT4048, it provides high-resolution color sensing, ambient lux measurement, and correlated color temperature (CCT) calculation. Its advanced 26-bit measurement architecture and automatic full-scale range detection allow it to accurately measure both very low and very high light levels without requiring manual calibration or range switching.

Designed for reliable operation in demanding environments, the OPT4048 features excellent infrared rejection, making it suitable for use behind dark or tinted optical covers. The board supports continuous and one-shot measurement modes, programmable conversion times, threshold detection, interrupt generation, CRC-protected(Cyclic Redundancy Check) data, and a high-speed I²C interface for dependable data acquisition. These features make it ideal for smart lighting, automatic display brightness control, camera white balance, environmental monitoring, medical devices, and industrial optical sensing applications.
