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 onboard 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 onboard voltage level translators make it compatible with the 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.
To assemble the Pan-Tilt hat you have to follow these steps:
