WayinTop PCA9685 PWM Servo Motor Driver Module 16 Channel 12 Bit I2C Interface for Arduino Robot

【The PCA9685】is a 16-way steering gear control; Power supply voltage is DC5-10V; All PWM output lines have a 220 ohm series resistor protection with which can easily drive LED.
【I2C Interface】It offers an I2C interface to easily communicate with control boards, which makes it very easy to use for Arduino or similar programmable boards that support the I2C protocol.
【Highly Outputs】On the upper right of the board there are six jumpers that allows to change the default I2C address, which is 0x40 (in binary 0b0100 0000) up to 0x7F (in binary 0b111 1111). As a result, you can chain multiple boards together, achieving up to 992 PWM outputs with 62 chained boards.
【Widely Applications】 Can be used to control steering gear, robots, LEDs, motors and other equipment.
