PhysicalDimensions

The pins on the pin header are spaced 100 mil apart. The PCB is 1.34 inches long on the sides
parallel to the pins on the pin header and 0.8 inches long on the sides perpendicular to the pin
header.
FunctionalDescription
The Pmod Color utilizes the TCS3472 to detect color in the near vicinity. While communicating with
the host board via the I²C protocol using an I²C address of 0x29 users can measure color. A user
controlled white LED is also provided to help illuminate the color of interest; the LED is very bright so
it is recommended that users do not stare at the light.
