NOTE: This product compatible with Raspberry Pi 3 Model B+, Raspberry Pi 4 Model B, and Jetson Nano.
Not compatible with Raspberry Pi 400, Raspberry Pi Pico and Raspberry Pi Compute Module 4.
This is a 2-DOF pan-tilt hat based on Raspberry Pi 40PIN GPIO. It can directly be used once plugged into the Pi board’s GPIO. Meanwhile, the board makes the Raspberry Pi GPIO pins led out for your convenient use. With the I2C interface adopted, the module allows your Pi to control the camera movement and light intensity detection only using 2 signal lines. The on-board PCA9685 chip can output 12-bit resolution PWM to control the rotation of the pan-tilt. In addition, it comes with onboard TSL25911FN and built-in ADC that could make responses to light similar to human eyes, which is helpful for enhancing module performance; The on-board voltage level translators make it compatible with 3.3V/5V operating level. There is a specific acrylic board for fixing the Raspberry Pi camera on this product.
Through actual tests, it is proven that this module is compatible with all series types of Raspberry Pi and works well with the Jetson Nano board. It can do the 2-DOF motion in the horizontal and vertical directions, which is suitable for image monitoring/recognition and tracking when installed a camera. Besides, when combining an IR sensor or Ultrasonic distance sensor, it can be turned into a detection device to make a robot sense and avoid the surrounding obstacles. Of course, you can use it with other various sensors to complete your interactive works by Raspberry Pi or Jetson Nano.
Note:
1.The Pan-Tilt HAT is unassembled, you need to get it done by yourself.
2.Raspberry Pi board and Camera are not included.Assembly

Jargon buster
Plain-language definitions for the technical terms used above.
- 12-bit resolution
- 12-bit resolution means the sensor’s measurement is divided into 4096 possible digital values. Higher resolution can make small changes in motion or tilt easier to detect, as long as the sensor range and noise are suitable for the project.
- ADC
- An analogue-to-digital converter reads a changing voltage and turns it into a number the microcontroller can use. It matters when connecting analogue sensors such as light, sound, or variable-resistor sensors.
- Ambient light sensor
- A sensor that measures the general brightness of light falling on it, similar to how a device can adjust screen brightness automatically. It matters when you want a project to react to room lighting, daylight, shadows, or covered/uncovered conditions.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
