PWM1 LOW Control/PWM input for OUT1

Two general-purpose MOSFETs (can be used as level-shifters or high-current outputs)

The band is an "off-the-shelf" band that holds the watch in pretty well

Addressable High-Density RGB 72-LED Strip, 5V, 0.5m (SK6812) POL_Original Zumo 32U4 Robot PWM1 LOW Control/PWM input forThis high density, 0. 5 meter long strip contains 72 RGB LEDs that can be individually addressed using a one wire interface, allowing you full control over the color of each RGB LED. The flexible, waterproof strip runs on 5 V and can be chained with additional SK6812 or WS2812B strips to form longer runs or cut apart between each LED for shorter sections.
