- Nice and compact. - Nice build quality. - Very bright. - Easy to connect and to work with. - Works nicely with PWM control.
None. works as advertized.
There are no resistors mounted on the board. They are not needed of you are working with microprocessors like the Arduino. They work directly on the PWM output pins of the Arduino (3,3V). At 3,3V the LEDs are very bright, and get warm, but extremes are not exceeded.
