User Manual

DotStars are 5 Volt devices. They

may

respond to 3.3V

signals, but this is not a guaranteed thing. If using a 3.3V

controller (Feather, Raspberry Pi, etc.), add a logic level

shifter to boost 3V logic to 5V…something like a

74AHCT125 (https://adafru.it/e5g) on the data and clock

pins.
