This is a unique ring - it has a florid body with 24 controllable LEDs. Maybe it will drive the inspiration out of you to make a glowing magic ring! There is a 1*1 square hollow-out in the middle of this module, where you can place a Grove - Encoder in and make it a rotary visual encoder!
24 LEDs, about 5.5 mA drive current for each channel.
Controllable LEDs with florid effects
Current: 5.5mA (for each LED)
Dimension: 4.5cm (ring diameter)
Net Weight: 12g
