Specification: _x005f_x000D_ Origin: Mainland China _x005f_x000D_ Type: Module _x005f_x000D_ Condition: New _x005f_x000D_ Model Number: PWM Servo Driver Board _x005f_x000D_ 1. The PCA9685 chip is wrapped around the center of the board. _x005f_x000D_ 2. Power input terminals _x005f_x000D_ 3. Green power indicator _x005f_x000D_ 4. Easy for you to plug in 16 servos at a time in 4 sets of 3-pin connectors (servo motor plugs are slightly wider than 0.1", so you can put 4 pairs of 0.1" connectors) _x005f_x000D_ 5. Reverse polarity protection for inputs on the terminal block _x005f_x000D_ 6. Cascade design _x005f_x000D_ 7. Place a large capacitor on the V+ line (you will need it in some cases) The external input voltage depends on this 10V1000uf capacitor. _x005f_x000D_ 8. Put a 220 ohm series resistor on all PWM output lines to protect them and can easily drive LEDs. _x005f_x000D_ Product Size: 62.00x25.00x13.00mm/ 2.44x0.98x0.51inch _x005f_x000D_ 1.This is an i2c communication with a built-in PWM driver and a clock. This means that this will be very different from the TLC5940 series. You don't need to keep sending signals to occupy your microcontroller! _x005f_x000D_ 2. It is 5V compatible, which means you can also control it with a 3.3V microcontroller and safely drive it to a 6V output (when you want to control a white or blue light with a 3.4+ positive voltage is also possible). _x005f_x000D_ The 3.6 address select pin allows you to hook up 62 driver boards to a single i2c bus for a total of 992 PWM outputs. That would be a very large resource. _x005f_x000D_ 4. about 1.6Khz adjustable frequency PWM outputs _x005f_x000D_ 5. 12-bit resolution for stepper motor ready outputs, which means 4us resolution at 60Hz update rates _x005f_x000D_ 6. Configurable push-pull outputs or open-circuit outputs _x005f_x000D_ 7. Output enable pin to quickly disable all outputs _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ Note: _x005f_x000D_ Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! _x005f_x000D_ Please allow 1-2cm measuring deviation due to manual measurement. _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ _x005f_x000D_ Included: _x005f_x000D_ 1* PWM Servo Driver Board 1.
