{{bloc-etroit|text=On the left side of the expansion board is a set of three pins surrounded by a box and labeled “5V”, “GND”, and “VOUT”. The “5V” pin is connected to the Raspberry Pi’s 5V power rail, while the VOUT pin provides access to the driver board’s motor supply voltage after reverse-voltage protection. If a suitable voltage regulator is connected to these three pins, it can generate 5 V to power the Raspberry Pi from the board’s motor supply voltage. We suggest using our S7V7F5 switching step-up/step-down regulator, which has a 2.7 V to 11.8 V input voltage range (similar to that of the DRV8835) and can supply up to 1 A of current to the Raspberry Pi.}}&lt;br /&gt;

&lt;br /&gt;
When adding a voltage regulator to the motor driver board, take care to orient it correctly: note that the motor driver board’s VOUT pin should connect to the regulator’s VIN pin, while the regulator’s VOUT pin should connect to the motor driver board’s 5V pin.&lt;br /&gt;
&lt;br /&gt;
There are several considerations to keep in mind when powering the Raspberry Pi through a voltage regulator in this way:&lt;br /&gt;
&lt;br /&gt;
* You must never connect a different power supply to the Raspberry Pi (including through its USB Micro-B receptacle) while the regulator is connected, as doing so will create a short between the voltage regulator’s output and the external power supply that could permanently damage the Raspberry Pi, the regulator, and/or the power supply.&lt;br /&gt;
* Your motor power supply must be an acceptable voltage for your regulator (as well as for the DRV8835).&lt;br /&gt;
* The regulator should be able to handle the power requirements of the Raspberry Pi. The Model B+ typically uses a few hundred milliamps at 5 V, although its current draw can exceed 1 A if it is also supplying power to USB devices and other peripherals. While linear regulators like the 7805 might fit in the regulator mounting location, they could generate excessive heat or shut down at higher input voltages and output currents. We recommend using a switching regulator (like our S7V7F5, as mentioned above).&lt;br /&gt;
