#10Gtek# PCA9685 16 Channel 12-Bit PWM Servo Motor Board Module IIC for Arduino Robot or Raspberry pi
Description
The PCA9685 chip is wrapped in the center of the small boardPower input terminalGreen power indicatorIn 4 sets of 3-pin connectors, it is convenient for you to plug 16 servo motors at a time (the servo motor plugs are slightly wider than 0.1", so you can put 4 pairs of 0.1" connectors)Reverse polarity protection for input on terminal blockCascaded DesignPut a large capacitor on the V+ line (you will need it in some cases) The external input voltage depends on this 10V1000uf capacitorA 220 ohm series resistor is placed on all PWM output lines to protect them and drive LEDs easily.

Features:
- I2C interface, support up to 16 channels PWM output, 12 bit resolution per channel (level 4096), you can control the 16 way servo motor.
- Built-in 25MHz crystal oscillator, also be connected to external crystal oscillator, maximum 50MHz.
- Supports voltage: DC 5-10V, logic level: 3.3V.
- About 1.6khz adjustable PWM output, using only two pins, control 16 free-running PWM outputs, update rate at 60Hz can achieve 4us resolution.
- You want to make a robot, when we saw this chip, we quickly realized what an excellent add-on this would be.
