DEVMO PCA9685 16 Channel 12-bit PWM Servo Motor Driver I2C IIC Interface Shield Module Compatible with Servo Ar-duino Raspberry Pi

**** The customer feedback regarding this PWM controller board reveals a largely negative experience, particularly among those using it in conjunction with microcontrollers like Arduino for controlling servos. While some users managed to get the board to respond to certain I2C addresses, a significant number reported malfunctions where the controller failed to produce any output despite proper connections and configurations. One reviewer expressed frustration over the lack of documentation, which left them guessing about troubleshooting the issues encountered. Critics have pointed out that the board does not appear to be an authentic product but rather a clone, causing concerns over its reliability and effectiveness for various projects. The absence of visual indicators, such as an LED to signify PWM or servo signals being sent, has left users in the dark when trying to diagnose functionality. Although there was an acknowledgement of the product's potential, many have been left disappointed by its inConsistency and overall performance. In summary, this PWM controller seems to struggle with basic functionality and offers little in the way of guidance or user support, ultimately leading many users to recommend buying an alternative product for reliable results. **
