Raspberry Pi 3B+ Servo Motor Controller PWM Kit, 2-DOF Pan-Tilt HAT for Raspberry Pi Light Intensity Sensing Control Camera Movement I2C Interface, Onboard PCA9685 Chip 12-bit PWM Resolution
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. Specific acrylic board to fix the Raspberry Pi camera, make it easy to install
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.
