Pan-Tilt HAT

Forget having to use a fixed camera in your Pi projects by giving it pan-and-tilt motion using this ready-assembled module that fits right on top of the Pi.

  • Pan-tilt module (180 degrees motion through each axis) with two servos
  • HAT with two servo channels, one PWM or NeoPixel RGB (or RGBW) LED channel
  • Right-angled header pre-soldered to underside of HAT for servo and LED channels
  • Slot to route servo, LED, and camera cables through
  • Acrylic mount to hold Pi camera and NeoPixel strip (with diffuser) in place
