On customer's request we can deliver the layout with soldered goldpin connectors. For this purpose, please leave the information in the commentary to the order. |
Description
The two-channel H-bridge TB6612FNGisa powerful controller capable ofcontrollingtwo DC motors. The module contains a soldered-on system with goldpin leads, with a standard 2.54 mm raster. On the board there are also necessary passive elements, which makes that for proper operation of the system it is enough to connect with microcontroller or starter kit e.g.Arduino.
For Arduino users there is a library availableto makethe moduleeasy touse. TB6612 chip can serve as a controller of Polol micro motors.If the motors will beexposed to stoppage, it is recommended to connect channels in order to achieve higher current efficiency.

All logical signals are internally pulled to ground. The maximum PWM frequency is 100 kHz.
For higher current capacity (2 A), both channels can be connected. To do so, connect :
- AO1 to BO1
- A02 with BO2
- PWMA with PWMB
- AIN1 with BIN1
- AIN2 with BIN2
Diagram
The module contains a soldered bridge with goldpin leads, with a standard 2.54 mm grid. Filtering capacitors are also placed on the board, which makes the proper connection to the microcontroller sufficient for the system to work properly.
Othermotor controllers, including a separateTB6612, are also available.
