Pinouts

Signals have been pinned out on traditional pins (2,54 mm pitch). Nogoldpinpins are soldered to the module, they can be purchased separately.

Pin Description
VCC Power supply for logic part.
VMOT Power supply for motors.
GND Ground.
A01 A02 Channel A outputs.
B01 B02 Channel B outputs.
PWMA PWM signal of channel A.
PWMB PWM signal of B channel.
STBY Should be pulled up to VCC to turn on the system, low state (default) switches the system to sleep state (low power consumption).
AIN1, AIN2 Controls the direction of channel A.
BIN1, BIN2 Controls the direction of channel B.

All logic signals are internally pulled to ground. The maximum PWM frequency is 100 kHz.

The TB6612 chip can be used as a controller forPololu micromotors. If the motors will be exposed to stalling, it is recommended to merge the channels in order to achieve higher current capacity. To do this, connect the following leads together:

  • AO1 with BO1
  • A02 with BO2
  • PWMA with PWMB
  • AIN1 with BIN1
  • AIN2 with BIN2
