Warning: The WS2812B seems to be more sensitive than our original TM1804-based LED strips. We recommend connecting a capacitor of at least 100 μF between the ground and power lines on the power input and generally following good engineering practices when handling and using this product (e.g. take precautions against electrostatic discharge (ESD) and avoid making or changing connections while the circuit is powered). If the strip does get damaged, it is often just the first LED that is broken; in such cases, cutting off this first segment and resoldering the connector to the second segment brings the strip back to life.
