Overview:
This is a 2-DOF pan-tilt kit designed for Raspberry Pi. With onboard PCA9685 PWM chip and TSL2581 ambient light sensor, it allows the Pi to control camera movement and sense light intensity through I2C interface.

Note: Raspberry Pi and camera are NOT included!!!

Features:
Raspberry Pi connectivity, compatible with Raspberry Pi Zero/Zero W/Zero WH/2B/3B/3B+
I2C interface, only 2 pins are required for moving and light intensity sensing
Onboard PCA9685 chip, provides 12-bit resolution PWM signal for moving control
Onboard TSL2581FN light-to-digital converter, with embedded ADC, provides a value that approximates the human eye response to assist the module
Onboard voltage level translator, compatible with 3.3V/5V operating voltage
Specific acrylic board to fix the Raspberry Pi camera, make it easy to install
