Compact size
Good accuracy for the price. The module is very small which helped fit it into my tight enclosure.

Works with STM32
Integrated easily into my STM32 project. The UART communication is stable and the color readings are consistent.
5 FAQ
Q: Does it come with connecting wires?
A: No, the module comes with pin headers only. Cables need to be purchased separately.
Q: Do you provide an Arduino library for this?
A: We provide sample code on our GitHub repository which is compatible with Arduino IDE.
Q: What is the maximum detection distance?
A: For accurate color recognition, we recommend a distance of 5mm to 10mm from the target.
Q: Is this module safe to use with 5V logic?
A: Yes, the operating voltage range is 3.3V to 5.0V DC, so 5V logic is supported.
Q: Can this be used outdoors in sunlight?
A: It is recommended for indoor use. Direct sunlight may interfere with color accuracy.
