I use the Raspberry Pi3+ and pca9685 to control 20 standard servos. The power supply is 6v. However, when driving them, the height calculation error causes the servo to not move. As a result, the board burns here. I want to ask if it can be used?#pca9685

Hello X YY,

 

You may want to use separate power supplies to meet with the limiting values for the PCA9685. Please note table 13 and table 14 from datasheet where states the operating power supply voltage (VDD) range of 2.3V to 5.5V and supply current (IDD) is 6mA to 10mA; with a 5.5V tolerant inputs (VI/O).

 

I hope this information can be helpful.

 

Have a great day,

Paulina
