b'voltage on VIN will be about 4.65V. However, if you power the RedBoard through the barrel jack (highlighted in the picture), the VIN pin will reflectC106that voltage. For example, if you were to power the barrel jack with 9V, theC106 SCLC106 SDAvoltage out on VIN would also be 9V.RX TX 13 AREF3.3V GNDNotice that the voltage range listed on theIOREF I/O 135V 12RESETRedBoard near the barrel jack is 715V.3.3V ~11S T A R TS O M E T H I N G ~105VThis means that the recommended inputGND ~9POWER ANALOG IN ON 8voltage should always be at or aboveGNDVIN DIGITAL (PWM ~) 77V or should be at or below 15V.

To make working with ICs easier and to make them breadboard-compatible, they are often added to a breakout board, which is a printed circuit board that connects all the ICs tiny legs to larger ones that fit in a breadboard. The motor driver board in your kit is an example of a breakout board.The guts of an integrated circuit, visible after removing the top.90 : circuit 5a'
