16-CH Servo Motor Controller/PWM Servo Driver Board for Arduino Robot

- A product for Arduino that works with official Arduino boards. - This is a i2c-controlled PWM driver board with a built-in clock， which is quite different from TLC5940 series. You don’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 allow 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 0.1", so you can put 4 pairs of 0.1" connectors).- With reverse polarity protection for input.- Cascade design.- Put a bulky capacitor on the V+ line (sometimes you need it).- Put 220 ohm resistance components onto all PWM output lines, so as to protect them, and you can easily drive the LED.GeneralModelN/AQuantity1 setMaterialFR4SpecificationEnglish Manual / SpecYesPacking List1 x Servo controller boardPackage Weight:0.018kg (0.040lb)Package Size:6.2cm x 2.6cm x 1.2cm (2.36in x 0.79in x 0.39in)
