Runs on a single AAA battery for many hours (even 'nearly dead' batteries will work)
The PWM is built into each LED-chip so once you set the color you can stop talking to the disk and it will continue to PWM all the LEDs for you
we suggest it for use with single board computers (or desktop/laptops
Max current draw per RGB LED: ~60mA (20mA max per Red
Pololu 5V, 9A Step-Down Voltage Regulator D24V90F5 tv-b-gone Runs on a single AAAThis synchronous switching step down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 5 V while allowing a typical continuous output current of up to 9 A. Typical efficiencies of 80% to 95% make this regulator well suited for higher power applications like powering motors or servos, while high efficiencies are maintained at light loads by dynamically changing the switching frequency, and an optional shutdown pin
