Building circuits just got easier with these tiny circuit boards that make all those weird parts fit into a standard solderless breadboard. The pins are labeled, and each board has a scribble strip so you can remind yourself what it’s for.
The LED Crouton was designed for a four-lead 5mm RGB LED, but it can also fit two-lead LEDs like 3mm, 5mm or 10mm too. Match the flat side of the LED with the silkscreen and use the B and C pads.
1. Solder two 4-pin headers on the bottom of the board (make sure they’re straight)
2. Solder the LED on the top of the board, lining up the flat side of the LED with the flat side of the silkscreen
