New Product Ideas / Re: Tiniest possible arduino

« on: December 12, 2024, 02:36:55 AM »

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)

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.
