The H bridge TB6612FNG is an effective driver of engines in a small package SSOP24. The company Pololu went out to meet the expectations of users and created a module containing the layout of the TB6612FNG , and is also necessary for the correct functioning of the passive components.
|For users available Arduino library to facilitate module maintenance.|
|VCC||food logical parts|
|AO1 AO2||the output of the channel And|
|BO1 BO2||output channel B|
|PWMA||the PWM signal of the channel, And|
|PWMB||the PWM signal of channel B|
|STBY||you must pull up to VCC to turn on the system, a low state (default) puts the system in sleep mode (energy saving)|
|AIN1, AIN2||direction control channel And|
|BIN1, BIN2||direction control, channel B|
All signals, the logic is internally pulled to ground. The maximum PWM frequency is 100 kHz.
|The motor rotates at the maximum given speed using PWM (different from 0) in a clockwise direction.|
|The motor rotates at the maximum given speed using PWM (not equal to 0) in a counterclockwise direction.|
The system can serve as a TB6612 driver mikrosilników Pololu. If the engines will be put on hold, we recommend combining the channels for greater loading efficiency. For this you need to connect the following conclusions:
The module contains soldered a jumper to conclusions goldpin, with standard pitch of 2.54 mm On the PCB and placed the filter capacitors, which makes that to work properly the system is quite relevant connections to the microcontroller. The scheme is available at this address.
