Questions tagged [led-strip]
LED Strips come in two designs, both on Flex Printed Circuits (FPC). 1. Simple LED + Resistor versions, typically with multiple parallel segments of three LEDs with matching resistors. 2. Digitally controllable with embedded controllers. Data is wired in series while power is paralleled by segments or pixels. Both have different and similar application challenges.
