16-Channel 12-bit PWM/Servo Drive shield module I2C PCA9685 For Arduino NEW
- It is an i2c-controlled PWM driver with a built-in clock. It is not necessary to continuously send the signal by tying the microcontroller, it is completely free!
- It conforms to 5V, which means that you can control it from a 3.3V microcontroller and continue to drive up to 6V output (this is useful when you want to control white or blue LEDs with 3.4+ voltages ahead )
- 6 address selection pins so you can connect up to 62 of these on a single i2c bus, for a total of 992 outputs.
- PWM adjustable frequency up to about 1.6 KHz.
- 12-bit resolution for each output - for servos, which means about 4 seconds of resolution with a refresh rate of 60 Hz.
- Configurable push-pull or open-drain output.
- Output enable pin to quickly disable all outputs.
- The PCA9685 chip is wound in the middle of the panel.
- Terminal block for power supply input (or the 0.1 'breakouts on the side can be used)
- Protection against inversion of polarity on the input of the terminal board
- LED with good green power
- 3-pin connectors in groups of 4 so you can connect 16 servos simultaneously (the Servo connectors are slightly wider than 0.1 'so that you can stack 4 one next to the other on 0.1' header.
- 'Chain-able' design.
- A place to place a large capacitor on the V + line (in case you need it)
- 220 ohm series resistors on all output lines to protect them and can easily drive LEDs.
