If you’ve had ideas for a project that depends on the ability to sense different spectrums of visible light and react based on those measurements, the ISL29125 breakout board may be just what you need. The ISL29125 breakout board makes it very easy to sense and record the light intensity of the general red, green, and blue spectrums of visible light while rejecting IR from light sources. You can then use these color sensor readings for the purposes of logging and finding patterns, or creatively calculate and make control decisions in your electronic projects.
Each pin from the ISL29125 has been broken out to allow you to interface with it, SDA, SCL, 3.3V, GND, and even an optional INT pin is available for use. The ISL29125 Light Sensor operates at 3.3V but if you plan on using this chip with a 5V microcontroller make sure to use a logic level converter.

Jargon buster
Plain-language definitions for the technical terms used above.
- ADC
- An analogue-to-digital converter reads a changing voltage and turns it into a number the microcontroller can use. It matters when connecting analogue sensors such as light, sound, or variable-resistor sensors.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- GND
- GND is the ground or reference connection (0 V) for a circuit. When connecting two devices together, their grounds must be joined so both agree on what counts as a low or high signal.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
