16 Channel 12-bit PWM/Servo Driver-I2C interface PCA9685 module Raspberry pi shield module servo shield shield

   This is a use i2c communication, with built-in PWM drive and a clock. This means that it will have a very different and TLC5940 series. You don't need to constantly send signals to take up your SCM!

   It is 5 V compatible, which means you can also use a 3.3 V single-chip microcomputer control and drive safely to 6 V output (when you want to control white or blue light may use 3.4 + positive voltage)

   6 address selection that you can put the 62 driver pin board hung on a single i2c bus, a total of 992 road PWM output. It will be a very large resources.

   About 1.6 Khz frequency modulation PWM output

   Output 12 resolution for stepper motor, which means that at 60 hz update rate can reach 4 us resolution

   Configurable push-pull output or open circuit output

   The output enable pin can disable all output quickly

   PCA9685 chip was wrapped in the middle of the small plate

   L power input terminals

   L green power light

   L in four groups of 3 pin connector convenient you an insert 16 servo motor, servo motor plug slightly wider than 0.1 ", so you can put 4 to 0.1 "joint)

   L input reverse polarity protection in a patch panel

   L cascade design

   L V + online placed a large capacitance (in some cases you will need) peripheral input voltage depends on the 10 largest v1000uf capacitance

   L all PWM output line put a 220 ohm resistor to protect them, and can be easily drive leds.
