16-Channel Servo/PWM Shield

Description

Building a robot with a ton of servos or a project that need 16 independently dimmable LEDs? This shield is for you! This shield is based on the PCA9685 16-channel PWM IC. It lets you assign a separate duty cycle to each of the 16 channels to control a servo or dim an LED.
