I am very new to Raspberry pi, especially electrical components. And when I am working with hooking up a digital LED light strips, I am planning to plug it into a 16 channel PWM/Servo hat. But I stumbled into these two similar things (Hat, and a driver). My question is what is actually the difference between a Servo Hat and Servo driver. As you can see from the item description below: https://www.adafruit.com/products/815 https://www.adafruit.com/products/2327
After looking at the description, it seems like they are offering the same functionalities (Serving 16 channels of 12-bit PWM output), but I am just wondering what would be the difference besides the placement of the hat and driver.
