Description
Product Introduction:
- 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.
- It is 5V compatible, which means that you can also use a 3.3V microcontroller to control and safely drive to 6V output (when you want to control the white or blue indicator light, 3.4+ positive voltage is also possible)
- 6 address selection pins allow you to handle 62 driver boards on a single i2c bus, with a total of 992 PWM outputs. That would be a very large resource.
- About 1.6Khz adjustable frequency PWM output, ready to output 12-bit resolution for stepping motors, which means that the update rate of 60Hz can reach 4us resolution.
- Configurable push-pull output or open-circuit output, output enable pin can quickly disable all outputs.
Product Features:
- PCA9685 chip is wrapped in the center of the small board
- Power input terminal
- Green power indicator
- It is convenient for you to insert 16 servo motors at a time in 4 sets of 3-pin connectors (the plug of the servo motor is slightly wider than 0.1″, so you can put 4 pairs of 0.1″ connectors)
- Reverse polarity protection of the input on the wiring board
- Cascade design
- Place a large capacitor on the V+ line (you will need it in some cases). The larger external input voltage depends on the 10V1000uf capacitor
- A 220 ohm series resistor is placed on all PWM output lines to protect them, and can easily drive the LED.
