Описание
The H-bridge TB6612FNG is an efficient motor driver in a small and SSOP24 housing. Pololu company has met the expectations of users and created a module containing TB6612FNG chip and passive components needed for its proper operation. Signals are provided on traditional pins (2.54 mm pitch). The module can be plugged into contact board or connected with wires.
All logic signals are internally pulled to ground. The maximum PWM frequency is 100 kHz.

The TB6612 chip can be used as a controller for Pololu micromotors. If the motors will be exposed to stalling, it is recommended to merge the channels 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
Schematics
The module contains a soldered bridge with goldpin leads, with standard 2.54mm spacing. There are also filtering capacitors on the board, which makes the proper connection with the microcontroller sufficient for proper operation. The schematic is available at this address.
We also offer other motor controllers including separate TB6612 chip.
