These incredibly small Dotstar APA102–2020 surface-mount LEDs are an easy way to add a lot of very tiny (but bright!) colourful dots to your project. They're mini versions of the ones in our digital DotStart strips and matrices with full chainable 2-wire control. They are just mind-bogglingly small. They are a mere 2mm x 2mm (way smaller than APA102-5050-RGB), which makes them pretty darn tiny so they might be a bit difficult to hand solder. SMT techniques with solder paste and hot air will work best here.
There are three LEDs inside, red green and blue. The RGB LEDs are controlled by a tiny chip that takes a 24-bit colour level via the clock and data in and then does all the PWM control for you. So you just 'set' the colour data once. Like DotStars (and the similar NeoPixels) you can chain them together, the output of one leading into the input of another for near-infinitely long strips.
Comes in a strip of 10 pieces. If you order more than one strip, it will come as multiple strips of 10, not one long strip.
Please note this is a surface mount part! It is possible to solder thin wires to the pads but its designed for use on a SMD PCB.
