6 LED Circle G2

The 6 LED Circle G2 is a 2.0" by 2.6" double-sided circuit board with a mounting pin on the back side. It has 6 single or bi-color LEDs that will display various user-selectable patterns. There is an IR emitter and receiver for two way communication to other blinkie boards. This blinkie design was introduced in 2012 at Musecon

The 6 LED circle was the 1st blinkie design we created. It was super successful, and we ran through the original set of circuit boards. When it came time to order a new set, we made a number of improvements.

Some of the changes we made over the old design:

• New battery solution, using the longer-life CR2032 batteries.
• Rounded corners.
• A larger pin back.
• A design supports up to 10mm LEDs.
• Made the circuit traces a little wider.
