f 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

Hardware Overview

The ISL29125 Breakout Board is quite simple in terms of parts. It consists of the sensor chip itself, two decoupling capacitors and 3 pull-up resistors for the I2C and interrupt lines.

The main header is what allows you to interface with the board. Simply connect power (3.3V) and ground to the designated vias. Connect the I2C lines – SDA and SCL – to the corresponding pins on your microcontroller. If desired, you can also connect the !INT pin to a interrupt pin of your microcontroller. Make sure you use 3.3V for power and logic. The chip is not 5V tolerant and will be damaged if you apply 5V to power or any of the inputs. Use a logic level converter if you’re controlling the chip with a 5V microcontroller.

If you want to disable the on-board 10kΩ I2C pullup resistors – in case you want to use those built into your microcontroller or other external pull-ups – simply cut the two traces between the three pads on the backside of the board. If you decide you want the pull-ups later, you can always solder the pads back together.

Now that you’re familiar with the board, let’s get it up and running.
