PCA9685 16 Channel 12-bit PWM I2C Servo Driver Shield for Arduino PIR it is the preferred isolatedPCA9685 PWM Servo Driver Shield interface PCA9685 (Compatible) You do not need to continuously send it signal tying up your microcontroller, its completely free running! It is 5V compliant, which means you can control it from a 3. 3V Arduino and still safely drive up to 6V outputs 6 address select pins so you can stack up to 62 of these on a single i2c bus, a total of 992 outputs thats a lot of servos or LEDs Adjustable frequency PWM up to about 1. 6
