DRV8833 motor drive module can directly replace tb6612 drive module, and pins are basically compatible.
Features:
Size: 22*19mm
Input voltage: 2.7V 10.8V
Output current of single H-bridge: 1.5A, which can drive two DC deceleration motors.
Built in over-current protection, short-circuit protection, under voltage locking and over temperature protection. With low power sleep mode.
Application: it can drive DC motor under 1.5A and 4-wire stepping motor.
Pin description:
Ani1: logic input control port of AO1, level 0-5V.
Ain2: logic input control port of AO2, level 0-5V.
Bni1: logic input control port of Bo1, level 0-5V.
BIN2: logic input control port of Bo2, level 0-5V.
AO1 and AO2 are one H-bridge output ports, which are connected to two pins of a DC motor.
Bo1 and Bo2 are two H-bridge output ports, which are connected to two feet of another external direct motor.
GND: ground.
VM: chip and motor power supply pin, voltage range 2.7 V 10.8 v.
STBY: grounded or suspended chip does not work, no output, connected to 5V; level 0-5V.
NC: empty feet

Basically compatible with tb6612 module pin.
Usage of DRV8833:
Drv8833 is double drive, that is, it can drive two motors
The IO ports controlling the two motors are as follows
STBY port is connected to IO port of single chip microcomputer, and the zero clearing motor stops completely. Set 1 to control the forward and reverse rotation through ain1 ain2, Bin1 and BIN2
VM connected to power supply within 12V
GND won't say much
Drive 1 way

AIN1 0 0 1
AIN2 0 1 0
Stop reverse forward
A01
AO2 connected to two pins of motor 1
Drive 2 ways
Pwmb connected to PWM port of single chip microcomputer
Truth table:
BIN1 0 0 1
BIN2 0 1 0

Bo2 connected to two feet of motor 2
Dual Motor Driver 1A TB6612FNG Microcontroller
Description:
The TB6612FNG motor driver can control up to two DC motors at a constant current of 1.2A (3.2A peak). Two input signals (IN1 and IN2) can be used to control the motor in one of four function modes - CW, CCW, short-brake, and stop. The two motor outputs (A and B) can be separately controlled, the speed of each motor is controlled via a PWM input signal with a frequency up to 100kHz. The STBY pin should be pulled high to take the motor out of standby mode.
Logic supply voltage (VCC) can be in the range of 2.7-5.5VDC, while the motor supply (VM) is limited to a maximum voltage of 15VDC. The output current is rated up to 1.2A per channel (or up to 3.2A for a short, single pulse).
Board comes with all components installed as shown. Decoupling capacitors are included on both supply lines. All pins of the TB6612FNG are broken out to two 0.1" pitch headers; the pins are arranged such that input pins are on one side and output pins are on the other.
Features:
Power supply voltage: VM=15V max, VCC=2.7-5.5V
Output current: Iout=1.2A(average) / 3.2A (peak)
Standby control to save power
CW/CCW/short brake/stop motor control modes
Built-in thermal shutdown circuit and low voltage detecting circuit
