This board provides four red/green bicolor LEDs that switch colors using a surface mount hex inverter. Designed to span the center gap in your breadboard, it provides a simple way to add four LEDs that are always illuminated and change color when you change their power. Connect ground and 5V on one side, connect four digital pins on the other side and set them high or low to flip between colors. The idea here is you have four LEDs that are all illuminated in green when everything is normal, but when you need to indicate an error you can flip the green to red.
Everything's attached. LEDs are big 5mm models but otherwise, the resistors, capacitor, and hex inverter are surface mounted.
The LEDs are red and green; pick the option on the right for what the default state is. You might notice down in the bottom right of the PCB itself there's a place to cross off "R" or "G" so if you order two different models you can tell which is which. And just in case I later get some blue/white bicolors, or you have some yourself, there's a "B" and "W" to mark off as well.
This square board, with its rounded corners to protect your fingers, is only 0.8 by 0.8 inches, or about 20 x 20 millimeters.
