Tiniest possible arduino

[thesko]

Recently I've discovered this design for a 0.4" x 0.4" arduino compatible board:

My proposal:

• a similarily sized Tinyduino, possibly powered by a small battery cell
• a neopixel addon board which can be soldered to the bottom side of the board (using spacers)

Recently, I came across the schematic for a tiny arduino-compatible board measuring just 0.41 by 0.41 millimeters (0.4 by 0.41 inches), called a Tinyduino, and perhaps powered by a coin-cell battery. baldi's basics

really? great

So cool

Cool thank you.

Your proposal for a Tinyduino-like board with an add-on NeoPixel module sounds like an excellent compact design concept!

Using a small battery cell is a great idea, but make sure to consider power management to maximize battery life, especially with neopixels, which can draw significant current.
