The Raspberry Pi is a wonderful little computer, but one thing it isn't very good at is controlling DC Servo Motors - these motors need very specific and repetitive timing pulses to set the position. Instead of asking the Pi Linux kernel to send these signals, pop on our handy HAT or Bonnet.
These boards add the capability to control 16 Servos with perfect timing. They can also do PWM up to 1.6 KHz with 12 bit precision, all completely free-running.
Works with any servo that can be powered by 5V and take 3.3V logic level signals.
The Adafruit 16-Channel 12-bit PWM/Servo HAT or Bonnet will drive up to 16 servos or PWM outputs over I2C with only 2 pins. The on-board PWM controller will drive all 16 channels simultaneously with no additional Raspberry Pi processing overhead. What's more, you can stack up to 62 of them to control up to 992 servos - all with the same 2 pins!
Best of all, we even have a Python library you can use, so you'll be up and running instantly, to make your robotic creation com to life. The Adafruit PWM/Servo Driver is the perfect solution for any project that requires a lot of servos!
