A product for Arduino that works with official Arduino boards.nbsp;
This is a i2c-controlled PWM driver board with a built-in clockïŒŒ which is quite different from TLC5940 series. You donrsquo;t need to continuously send signals and occupy your MCU.
5V compatibility, which means that you can use 3.3V MCU to control and drive the output up to 6V (when you want to control the white or blue indicator light, 3.4V+ is also OK).
6 address select pins allownbsp;you to connect 62 driver boards to one i2C bus, total 992 channels of PWM output.
About 1.6KHz frequency modulation PWM output.
Get 12-bit resolution output ready for stepping motor, which means that the 60Hz update rate can reach to 4us resolution.
Configurable totem-pole output or open-collector output.
Output enable pin can quick disable all outputs.
PCA9685 chip is at the center of the board.
With power input terminal.
With green power indicator light.
Convenient to insert total 16 servos at the same time (the plug of servo is a little large than 0.1quot;, so you can put 4 pairs of 0.1quot;nbsp;connectors).
With reverse polarity protection for input.
Put a bulky capacitor on the V+ line (sometimes you need it).
Put 220 ohm resistance components onto all PWM output lines, so asnbsp;to protect them, and you can easilynbsp;drive the LED.
