Adafruit 16-Channel 12-bit PWM/Servo Driver - I2C interface (PCA9685) _BF25_10 This makes the ChronoDot very

This makes the ChronoDot very well suited for time critical applications that cannot be regularly synchronized to an external clock

solder closed the square jumper on the back

coaxial cable

up to 2A/channel

inside are three visible LEDs: a power LED (letting you know its plugged in and working) and RX/TX LEDs that you can use to help debug your connection

Adafruit 16-Channel 12-bit PWM/Servo Driver - I2C interface (PCA9685) _BF25_10 This makes the ChronoDot veryYou want to make a cool robot, maybe a hexapod walker, or maybe just a piece of art with a lot of moving parts. Or maybe you want to drive a lot of LEDs with precise PWM output. Then you realize that your microcontroller has a limited number of PWM outputs! What now? You could give up OR you could just get this handy PWM and Servo driver breakout. When we saw this chip, we quickly realized what an excellent add on this would be. Using only two pins,
