Wiring Diagram

Linked below is a wiring diagram for the completed project. It includes data connections (all three of them!), power connections plus the ESP-32 camera and servos to move the head to aim the camera. Both the camera and Nano broadcast direct to WiFi so there is no data connection between them. Also note, while the Nano will tolerate a wide voltage range on its VINN, it is important to feed the PCA9685 VCC with 3.3v as this is the maximum for the Nano’s control lines.
