A case for the narrow "two hole" version of the TCS3472 PCB from aliexpress/ebay.
You'll need to cut the two flanges of the PCB to make it fit. See the photos for cabling and assembly.
Use a 9x3 strip of perfboard cut to size for the I2C connectors and pins.
The two extra pins can be used to either
- make the LED and INT pins available -> connect the LED and INT pins or
- disable the built-in LEDs with a jumper or external switch -> connect the LED and GND pins
BTW: If you, like me, wonder about the difference between TCS3472 and TCS34725 - there is none, the latter is just the variant of the chip with address 0x29 and flexible, i.e. non 1.8V, I2C bus voltage.
Materials and methods
I used PETG as it is more flexible, PLA might break when you push both parts together.
Both parts can be printed without supports, if rotated accordingly.
