Raspberry Pi boards have only a handful of pins actually capable of hardware PWM, which becomes a real constraint the moment a project needs to drive more than a couple of servos independently. This HAT sits directly on the Pi's GPIO header and takes over all the servo timing itself, communicating over I2C and freeing the Pi from having to generate PWM signals in software - a method that's both less precise and more CPU-intensive than dedicated hardware. Sixteen channels at 12-bit resolution give enough headroom for a genuinely multi-servo robotics build, from a robotic arm to a hexapod, all controlled from simple I2C commands.
