Review on 🔌 Black NeoPixel Digital RGB LED Strip - 30 LED by Adafruit [ADA1460] by Cory Miles

Difficult to plan in advance for integration with other components. Because this product does not use a single specific chip specification. Users are told to expect a random LED strip among the WS2812b and SK6812, which have wildly different voltage limits. If you plan for the wrong minimum or maximum voltage levels for the rest of your project, the LED strip will either not turn on or, worse, will be damaged. Not to mention that the production documentation often says contradicting things about the true limitations of the device. They usually don't bother to distinguish between the minimum and maximum VCC levels (the available pin that the user connects to) and the internal VDD level. This is all very confusing, even for a simple project. To get around this, users should plan to use a separate 5V boost/pull/regulation module to power this device. If you integrate a 5V microprocessor, you can simply keep using the 5V regulated supply line for this LED strip, or use the microprocessor's VCC output with a compatible RAW input. This 5V voltage level is also backward compatible with older LED chips. eg WS2812.
