- Rounded Edges so they don't snag on clothing
- Teeny tiny but with 4 holes large enough to mount them on things using thread, safety pins, etc
- Clearly labeled connection points on front and back
- built in decoupling cap
- 0.1" headers to use with any 0.1" connector which is very common.
- Does not use SMD pads which tend to lift and ruin an LED
