Open Colorimeter LED Boards

Open Colorimeter LED Boards

We designed a complimentary LED board with approximately the same form factor as the Adafruit light sensor board. The LED board is connected to the light sensor board via a 4-pin cable and JST SH connectors. The open hardware KiCad design files can be found here: https://github.com/iorodeo/i2c_led

Features

  • Dimensions: 25.4 mm x 20 mm x 1.6 mm
  • Two 4-pin JST SH connectors
  • Four M2.5 through holes for mounting to the cuvette holder
  • Surface mount LED and resistor. Any 0603 LED can be used here.

In addition to white light, we currently have the following 10 wavelength options available:
