PCA9685pw module 12-bit PWM/ Servo Shield 16-way servo drive module AB5

PCA9685pw module 12-bit PWM / Servo Shield 16-channel servo drive module AB5 Product Features Has a built-in clock I2C control PWM driver. This means that unlike the TLC5940 series, you do not need to send signals continuously to bundle your microcontroller - its completely free! It complies with the 5V standard, which means you can control it with a 3.3V Arduino and still safely drive outputs up to 6V (which is useful for wanting to control white or blue LEDs with a 3.4+ forward voltage) 6 address select pins so you can stack up to 62 such buses on an i2c bus for a total of 992 outputs - which is a lot of servers or LEDs Adjustable frequency PWM up to about 1.6 KHz 12-bit resolution for each output - for servo, this means 4us resolution at 60Hz update rate
