LED Boards
Current-controlled LED boards for using with the Open Colorimeter instruments. They can also be used for any applications using STEMMA/Qwiic to incorporate a specific-wavelength LED. LED boards are available in a wide-range of UV, Visible and IR wavelengths.
Open Hardware Design
- PCB Size: 25.4 mm x 20 mm x 1.6 mm
- Two 4-pin JST SH connectors
- Four M2.5 through holes for mounting
- Surface mount or radial LED mounted in the center
- On-board voltage regulator enables operation from 3.3V to 5V input voltage
- Active 16mA (or 24mA) constant current LED driver which maintains stable LED current
LED Measurements & Specifications
We collect spectral data for each LED board using an Ocean Optics spectophotometer. For convenience all of this information is available in the gallery linked below. In addition to measured data, you can also find more LED specifications from the manufacturer and links to datasheets.
