DotStar FeatherWing - 6 x 12 RGB LEDs
PRODUCT ID: 3449
Description
A Feather board without ambition is a Feather board without FeatherWings! This is the DotStar
FeatherWing, a 6x12 RGB LED Add‐on For All Feather Boards! Using our Feather Stacking
Headers or Feather Female Headers you can connect a FeatherWing on top or bottom of your Feather
board and make your Feather board strut like a peacock at a rave.
Put on your sunglasses before staring into these 72 configurable RGB LEDs, they are super bright!
Arranged in a 6x12 matrix, each 2mm by 2mm sized RGB pixel is individually addressable. Only two pins
are required to control all the LEDs. On the bottom we have jumpers for the Data and Clock lines so you
can change them from the defaults. Works with any/all of our Feathers! You can cut the default jumper
traces and use any pins you like
To make it easy to start, the LEDs are by default powered from either the USB power line or Battery
power line, whichever is higher. Two Schottky diodes are used to switch between the two. This power
arrangement is able to handle 1 Amp of constant current draw and maybe 2A peak, so not a good way
to make a flashlight. It's better for colorful effects. A power MOSFET is set up and connected to the
ENABLE pin on the Feather so that when the Feather is disabled, the wing will also cut power.
