5V, 2A Step-Up/Step-Down Voltage Regulator S13V20F5 Shipping:1 day Current consumption: 30 mA (typical)

Current consumption: 30 mA (typical) when enabled

if you want to power the board with batteries or a regulated wall supply

Plug the shield onto the board

with a couple levels of PWM dimming for increasing current

The VZCR pin is the voltage reference output pin and can be used as a zero current (0 A) reference

5V, 2A Step-Up/Step-Down Voltage Regulator S13V20F5 Shipping:1 day Current consumption: 30 mA (typical)This tiny synchronous switching step up step down regulator efficiently produces 5 V from input voltages between 2. 8 V and 22 V. Its ability to convert both higher and lower input voltages makes it useful for applications where the power supply voltage can vary greatly, as with batteries that start above but discharge below 5 V. The extra compact board measures 0. 35 0. 475 , has a typical efficiency of 85% to 95%, and can supply typical continuous
