5V, 2A Step-Up/Step-Down Voltage Regulator S13V20F5 hub-module 2 x AAA LR03 batteriesThis powerful 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 board measures 8. 9 mm 12. 1 mm, has a typical efficiency of 85% to 95%, and can supply a typical continuous output
