This colorful rainbow is part of our weather series.
This is a rainbow solder-it-yourself through-hole kit that uses self-flashing red, yellow, green, and blue LEDs.
This board is part of our Alpenglow Beginning Soldering weather-themed series. This is a step up from our Happy, Angry, Chilly, and Surprising boards, featuring more LEDs and resistors! On this board you can practice using reference designators to match parts to their proper places on the PCB.
The radiant rainbow has the most LEDs out of all our weather boards with 11 LEDs. Instead of using just one CR2032 battery at 3V, we have included 2 CR2016 batteries that you stack (place in series) to create 6V and ensure that all the colors are bright and stay blinking for many hours! The purple soldermask combines with the red, yellow, green, and blue LEDs to create an almost full rainbow.
