Hi all - I’m looking to downsize… go small. What are the smallest programmable LEDs you know about?

SK6812MINI 3535 are the smallest I know of: http://www.aliexpress.com/item/addressable-2m-60LEDs-m-DC5V-SK6812MINI-3535-led-pixel-strip-NON-waterproof-with-60pixels-M-WHITE/32665636543.html

@Jason_Coon Im just about to order a ton of these myself!!

I really want some of these but want 30 leds/meter… guess I could just turn on half of them? How much are you getting them for?

@Justin_Eastman Have you seen these? https://www.adafruit.com/products/2954

@Justin_Eastman Im ordering the 144PM ones for $15.8USD per meter

Interesting, thanks everyone. There are some options!

I’m still on the hunt for a narrow Arduino to run them off. Anyone ever found anything on a board 10mm or less on it’s narrowest dimension?

@Robert_Atkins check these out https://www.aliexpress.com/item/Nano-V3-ATmega328-CH340G-Micro-USB-Pin-headers-NOT-soldered-Compatible-for-Arduino-Nano-V3-0/32664577152.html?spm=2114.13010608.0.94.5UE157 they are juts under 20mm width

You can use an ATTiny85 chip on its own, it’s less that 10mm across.

@Christian_Eaton A bare ATTiny chip doth not an Arduino board make :-). And @Leon_Yuhanov , at around 17mm wide, that’s double the kind of width I’m looking for. The ultimate goal is to make an LED “levitation wand”, and I’d want it to be something like 12mm OD tube.

@Robert_Atkins ​ You can program an ATTiny chip to light up a string of LEDs… I’ve got one in front of me doing just that!

@Robert_Atkins I just saw this on Tindie, looks to be less than 10mm: https://www.tindie.com/products/bobricius/beanduino-attiny85-super-small-digispark-clone/

@Robert_Atkins This one is just over, at 10.16mm: http://www.watterott.com/de/Wattuino-Nanite85

It’s cool that they’ve got built-in USB for easy programming, but it’s just a break-out for the ATTiny chip: anything that can do, you could do with just the chip on its own.

@Robert_Atkins , I just saw another one, meant to be soldered inline and powered from the strip: https://www.tindie.com/products/Danjhamer/chromatab

Oh that’s pretty cool! Thanks for the pointer.
