You can also solder your motor leads and other connections directly to the board for the most compact installation

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

5V, 2A Step-Up/Step-Down Voltage Regulator S13V20F5 Shipping:1 day The VZCR pin is theThis 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
