Product Information
PWM servo actuator drive board module robot controller IIC interface
Model Number：M2021028
When you encounter that the PWM output pin of the microcontroller chip is not enough in a project, this pca9685 and 16 way steering gear can quickly help you solve this problem.
As long as your main control chip has I2C communication, you can make the main control chip communicate with pca9685 to realize the simultaneous control of multiple steering engines.
Pca9685 16 way steering gear adopts I2C communication, built-in PWM driver and a clock, which means that it will be very different from tlcg940 series. You don’t need to constantly send signals to occupy your MCU
It is 5V compatible, which means that you can also use 3.3V MCU to control and safely drive to 6V output (when you want to control white or blue indicator, you can also use 3.4 + positive voltage). The address selection pin allows you to hang 62 drive boards on a single I2C bus, with a total of 992 PWM outputs, which will be a very huge resource, about 1.6kHz FM PWM output, ready to output 12 bit resolution for stepper motor, configurable push-pull output or open circuit output, and the output enable pin can quickly disable all outputs.
Features
Pca9685 chip is wrapped in the center of the small board. The power input terminal and green power indicator are in four groups of 3-pin connectors, which is convenient for you to insert 16 servo motors at one time (the plug of servo motor is slightly wider than 0.1, so you can put 4 pairs of 0.1 connectors) for the reverse protection of input on the wiring board.
A large capacitor is placed on the V + line (you will need it in some cases). The large peripheral input voltage depends on the 10v1000uf capacitor. A 220 ohm series resistor is placed on all PWM output lines to protect them and easily drive the LED
