Pololu 3.3V 2.5A Step-Up/Step-Down Voltage Regulator S13V25F3 Brand_i2Audio SD socket on the bottomThis synchronous switching step up step down regulator from Pololu efficiently produces 3. 3 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 3. 3 V. The board measures 0. 9 0. 9, has a typical efficiency of 85% to 95%, and can supply typical continuous output
