Good value, needs calibration

The hardware quality is solid. You do need to spend some time calibrating the white balance for your specific lighting conditions, but once set up, it performs well.

Reliable component

I've bought three of these now for different prototypes. They are consistent across units and handle voltage fluctuations well. Highly recommended for hobbyists.

Perfect for Arduino Projects

This sensor works flawlessly with my Arduino Uno. The I2C library is easy to use, and the color readings are surprisingly accurate for such a small module. Great for sorting projects.

Works but tricky for beginners

The sensor itself works, but I struggled a bit with the I2C address configuration. Would be nice if the documentation included more troubleshooting steps for common connection issues.

Excellent sensitivity

I used this on a line-following robot that needs to distinguish between colored paths. The sensitivity is excellent, and the integrated LED helps in low-light environments.

Fast shipping and great docs

Arrived quickly and was well-packaged. The pinout is clearly labeled, and there are plenty of example codes available online for various microcontrollers.

5 FAQ

Q: What is the maximum update rate for color readings?

A: The update rate depends on the integration time setting. At the fastest setting (2.4ms), you can achieve roughly 400Hz, though lower rates provide better accuracy.

Q: Is a 5V logic level safe for the I2C pins?

A: Yes, the board includes a voltage regulator and level shifting, making it safe to use with both 3.3V and 5V microcontrollers.

Q: Do you provide a Python library for Raspberry Pi?

A: We do not host our own library, but this sensor is fully compatible with the popular Adafruit CircuitPython TCS34725 library, which works perfectly on Raspberry Pi.

Q: Does this board come with header pins soldered?

A: No, the board is shipped with unsoldered header pins to allow for flexible mounting options. You will need to solder them yourself.

Q: Can this sensor detect colors through glass?

A: It can detect colors through clear glass, but the accuracy may decrease depending on the thickness and tint of the glass. Direct line of sight is recommended for best results.
