16 Channel PWM Servo Driver with I2C Interface

When you are in your project, encoun­tered a case where the micro-con­troller chip pwm out­put pin is not enough, then this PCA9685 16 road steer­ing to help you solve this prob­lem, as long as your main chip with I2C com­mu­ni­ca­tion func­tion, it is pos­si­ble to make the main chip and PCA9685 com­mu­ni­cate simul­ta­ne­ous­ly achieve a plu­ral­i­ty of ser­vo con­trol. It is a a use I2C com­mu­ni­ca­tion, built PWM dri­ve and a clock. This means that it will TLC5940 series are very dif­fer­ent. You do not need to con­stant­ly send sig­nals occu­py your micro­con­troller. It is 5v com­pat­i­ble, which means you can also use 3.3v micro­proces­sor con­trolled and safe dri­ving to 6v out­put.FeaturesAdjustable fre­quen­cy PWM up to about 1.6 KHzCon­fig­urable push-pull or open-drain out­putOut­put enable pin to quick­ly dis­able all the out­puts12-bit res­o­lu­tion for each out­put — for ser­vos, that means about 4us res­o­lu­tion at 60Hz update rate6 address select pins so you can wire up to 62 of these on a sin­gle i2c bus, a total of 992 out­puts — that’s a lot of ser­vos or LEDsPackage list16 Chan­nel PWM Ser­vo Dri­ver with I2C Inter­face x 1Wiki & External linksPCA9685 datasheet
