ARCELI 16 Channel PWM/Servo Driver IIC interface-PCA9685 for Raspberry pi shield module servo shield

• It is 5V compatible, which means you can control it from a 3.3V microcontroller and still safely drive up to 6V outputs (this is good if you want to control white or blue LEDs with forward voltages of 3.4 or more)
• 6 address select pins so you can connect up to 62 of them on a single i2c bus, total 992 outputs
• Adjustable frequency PWM up to approx. 1.6 KHz; Configurable push-pull or open-drain output manufacturer
• 12-bit resolution for each output - for servos this means a resolution of about 4us at a refresh rate of 60 Hz

Feature: An I2C controlled PWM driver with integrated clock. This means that unlike the TLC5940 family, you don't have to constantly send a signal that binds your microcontroller. 1. Output activation pin for quickly disabling all outputs 2. Terminal block for power supply (or you can use the 0.1 inch breakouts on the side) 3. Reverse polarity protection on terminal block input. 4. Green Power Good LED 5. 3-pin connectors in groups of 4, so you can connect 16 servos at the same time (servo plugs are slightly wider than 0.1 inches, so you can only stack 4 next to each other on a 0.1 inch head 6. Chain-ready design. 7. A place to place a large capacitor on the V+ line 8. 330 ohm series resistors on all output lines to protect them and make driving LEDs trivial 9. Soldering jumper for the 6 address selector pins. Package: IIC interface for 1 x 16-channel PWM / servo driver
