The Qwiic Visible Spectrum Emitter is based on the MultiSpecLED design by Ben Krasnow, but with slight modifications. The LEDs used in this product are less powerful and are placed closer together. Sparkfun has also made the product Qwiic-compatible by designing it around the LP55231 I²C LED controller. This design ensures that the product can be used for a variety of applications that require a broad-spectrum LED emitter.
The emitter comes with a USB-C port that allows you to connect a high-current 5V power supply for the LEDs. The back of the board features exposed copper that can accommodate a self-adhesive copper heatsink for applications that require active cooling. The LEDs can function at about 80% PWM cycle without the need for an auxiliary heatsink or active cooling, however, if operated at higher than that, the board will heat up quickly.
The Qwiic Visible Spectrum Emitter can be controlled using example Arduino code available in the SparkFun LP55231 Arduino Library. This feature allows even those with minimal coding experience to operate the product effectively.
