PCA9685 I2C 16 Channel 12 Bit PWM Controller Board

PCA9685 I2C 16 Channel Programmable 12 Bit PWM Signal Generator Board

Servo Motor Driver Circuit Module IIC Robot Arm Arduino Raspberry Pi 1.6kHz

     Thanks to this board you can add an extra 16 PWM outputs to your Arduino or other microcontrollers. It can be used in 16 channel led or servo motor driving applications. It provides 16 adjustable pwm output controls over 2 Pin serial communication. It has 12 Bit resolution. It can operate with DC 3.3V and 5V supply voltage. It has 3 Pin male motor connection output sockets. These sockets are suitable for connecting standard servo motor cables. This way servo motors can easily be plugged into and removed from the board directly.

     Thanks to the connection pins found on both ends of the board, it has a structure that can be attached to one another. Thanks to the terminal block connection on it, you can apply external supply from the V+ line. Reverse voltage protection is available. There is no need to drive the board continuously. With the 25 mhz crystal on the board it produces the output signals without interruption. It can continue doing this job for days.

     Important Note: On some board versions of this product, the V+ supply given over the terminal block is not directly connected to the servo motor outputs. For this reason the servo motors may not work despite power being given to the terminal block. In this use, the servo supply must additionally be given from the V+ line on the 6 pin header at the edge. If desired, by making an external connection between the terminal block V+ line and the servo motor V+ line, use with a single supply can be provided.
