Xmas Tree

Depending on what month you are viewing this description, you are either just in time, a little early, or perhaps really early for next Christmas.

It's a beautiful green circuit board, 3.8" by 3", with detailed silk screening for the branches and presents. 20 LEDs for the ornaments. This blinkie design was introduced in 2014 at Musecon 4 In 2018 we updated the design to use two single battery holders, and the newer 16F18313 chip.

• Twenty 3mm LEDs
