Then, with 5 volts set, add a 3.3-volt regulator to it such as the AMS1117. If you are using a mixture of 5 and 3.3 volts in a circuit, you will initially set the DC to DC buck-boost converter to 5 volts. The above circuit will provide consistent VCC from battery packs of a wide voltage range. TB6612FNG and Arduino Power Supply XL6009 DC Buck-Boost Circuit Furthermore, when the batteries become weaker, the DC motors can cause significant voltage drops across the power supply. This voltage drop can cause the Arduino board to reset. So, depending on the type of onboard regulator, you may have to recharge the battery pack sooner to avoid affecting the 5-volt regulator output.
With the battery pack configuration as above, there is going to be less headroom for the dropout voltage on the Arduino onboard 5 Volt regulator.

You can reach full battery discharge and still have enough headroom for Arduino 3.3 volt regulator dropout voltage. A battery pack with either two 3.6 volt Li-Ion/Li-Po or six 1.2 volt NI-MH cells in series will work for this setup.

Hence you can use the 3.3-volt version of the Arduino Pro Mini.

The TB6612FNG motor driver can operate on 3.3 volts. Arduino pins have to be configured as outputs to control the motor driver. Therefore, you can tie the TB6612FNG driver standby pin to VCC. The pins on the Arduino boards (ATMEGA) default to inputs. However, take note of the PWM connections, because these connections require specific Arduino pins to provide PWM. The Arduino compatible boards can connect directly to the motor driver. TB6612FNG Arduino Connection Motor Driver and Arduino Pro Mini Circuit Furthermore, if you are using a microcontroller with unpredictable pin states on bootup, you can use standby mode to ‘manually’ enable the motor driver following pin state initialisation. You can enable the dc motors by connecting the motor driver standby pin to Vcc supply. However, use the stall current rating from DC motor specifications as a guide to match other DC motors with this motor driver. The TB6612FNG can support four medium power Micro Metal Gearmotors in a four-wheel drive robot vehicle design.

If you are also interested in Raspberry Pi robot vehicles, view the following post for attaching this motor driver to a Raspberry Pi: So, if you use this motor driver with an Arduino Pro Mini and an NRF24L01 wireless module, you have a very powerful compact module for a programmable, wireless control robot. This breadboard friendly driver board will fit inside some of the smallest robots available, especially when connecting wires are soldered directly to the pads. Therefore, review this guide for pinouts and example circuit diagrams for 3.3 Volts and 5 Volts.
