Arduino I2C motor shield TB6612 + PCA9685

Product detailed description

The new version of the motor shield for Arduino UNO, Leonardo, ADK/Mega R3, Due, Diecimila and Duemilanove allows to control 2 stepper motors or 4 DC motors together with two servo motors. Communication with the Arduino motherboard takes place using the I2C bus, so only two data pins are needed for control. Two more pins are needed to control two servos. The servos are controlled directly from the motherboard Arduino and are also powered from it. The total number of data pins is therefore 4. This is a significant saving of pins on the Arduino board, and also due to the fact that the I2C interface was chosen for communication, the shield can be combined with other different shields. The Shield can also be stacked to control up to 64 stepper motors or 128 DC motors. There are 5 jumpers on the board for I2C address selection. Since the servomotors are controlled directly from the Arduino motherboard, only two are available in any case, on pins D9 and D10.

The basic circuit is PCA9685, which is used for communication via the I2C interface with the Arduino board and controls stepper and DC motors using two TB6612 drivers.

Remark:

• This product is not a standalone functional unit and may require professional installation.
• Product images are for illustration purposes only and may sometimes differ from the actual appearance of the item. However, this does not change its basic properties.
• After mounting the shield, please check that the pins from the bottom side do not touch the component housings on the bottom plate! This could cause a short circuit and destroy the shield or even the motherboard. Goods damaged in this way are not covered by the warranty!
