1pcs/lot! 16-way PWM steering gear drive board PCA9685 controller robot IIC suitable for MG90S SG90 MG995 |

Introduction: This is a built-in PWM driver and a clock using i2c communication. This means that this will be very different from the TLC5940 series.

You don't need to constantly send signals to occupy your microcontroller!

It is 5V compatible, which means you can also control it with a 3.3V microcontroller and safely drive it to 6V output (3.4+ positive voltage is also ok when you want to control the white or blue LED) 6 address select pins enable You can hang 62 driver boards on a single i2c bus for 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 stepper motor,

This means 4us resolution at 60Hz update rate Configurable push-pull or open-circuit output Output enable pin can be quickly disabled

All output features:

l The PCA9685 chip is wrapped in the center of the small board

l Power input terminal l Green power indicator

l It is convenient for you to insert 16 servo motors at a time in 4 groups 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) l Reverse polarity protection of input on the terminal board l Cascade design

l Put a large capacitor on the V+ line (you will need it in some cases) The maximum voltage of the peripheral input depends on this 10V1000uf capacitor

l Put a 220 ohm series resistor on all PWM output lines to protect them and drive LED easily.
