Soldered PWM & Servo Driver 16-Channel 12-bit PCA9685 breakout

This breakout drives up to 16 hobby servos or PWM-controlled outputs from a single I2C (a two-wire bus for talking to chips) connection, built around the NXP PCA9685. Each of the 16 channels has 12-bit resolution (4096 steps) and keeps its own PWM signal running once you set it, so your microcontroller does not have to hold the timing itself. A separate screw terminal powers the servos, so motor current never shares the rail with your logic supply.
