ESP32 and PCA 9685 - using 3 servos for now - can add up to 16 servos on one PCA 9685 module - can connect many PCA 9685 together for100s of servos :-)
I modified some code I found
Can display the 3 motors results on the ARC serial monitor

here it is with the Arduino with the PCA9685 - to control each servo individually
Downloaded Mickeys andDJ's firmware from here https://synthiam.com/Support/Hardware/Adafruit-16-Servo-Shield
I modified their code, added: Adafruit_PWMServoDriver pca9685 = Adafruit_PWMServoDriver(0x40);
for one PCA9685, if you want 2 PCA9685 just change the hex to (0x41) or 3 PCA9685 (0x42) and on and on...
in setup I added:
// Initialize PCA9685
pca9685.begin();
// Set PWM Frequency to 50Hz
pca9685.setPWMFreq(50);
If your Arduino does not have a SDA or SCL
use:
Analog 4 -> SDA
Analog 5 -> SCL
GND to GND
VCC to 5v from Laptop computer
make sure you add a separate power supply - 5 - 7.5 V to the PCA9685 for the servos
ARC connect Arduino at 57600 baud n settings
easy connection
works very good
EzAng
just tested it again , works well
separate 5 to 7.5 v power supply, I use into the PCA 9685
Arduino 5v - GND - from laptop - make sure the you use 57600 (in settings) when you connect to the Arduino from ARC
try all D0 to D15

Used it tonight with the Arduino code and the PCA 9685 and connected to ARC com5 -
Nothing would move until I added a separate 5 to 7.5 v power supply, I use into the PCA 9685
