LEDstimator

LEDstimator is a tool for artists and makers planning Neopixel, Dotstar, APA-102, WS2801, WS2811, WS2812b and other smart LED pixel projects. Simply select the type of LED pixel module you would like to use and enter the required pixel count. LEDstimator will then show you minimum and maximum current and power draw for that number of LEDs, plus estimates of run time for a given battery type and capacity.

LEDstimator also has a handy DC voltage drop calculator. Enter the cable length and gauge (in metric or imperial units), required current carrying capacity and starting voltage and LEDstimator will calculate the final voltage at the end of your power wiring.

Quickly and easily run “what-if” scenarios, trading off pixel density, power supply rating, battery capacity and run time. Avoid costly design mistakes before ordering cabling, power supplies and batteries!
