I did this a while back:

https://synthiam.com/Community/Robots/ESP32-and-ARC-Arduino-and-PCA-9685-20320

This post did not have any relevant information so I removed it.

Yes, I modified the Mick's software and loaded it to my "Arduino uno", and it worked just fine with all the info above. You did watch the video? I used it with the ESP32

I put : // Creat object to represent PCA9685 at default I2C address Adafruit_PWMServoDriver pca9685 = Adafruit_PWMServoDriver(0x40);

Try loading Mick's software to an Arduino  "as is".

I not using a Lattepanda , but The instruction say: download the Arduino firmware below. You can program on the Arduino Leonardo that's built into the LattePanda. Adding this firmware lets you connect ARC to the local Arduino and directly control the GPIO.

DJ's instructions - Download Arduino Leonardo Firmware: EZ-Genuino_Leonardo.zip. Last updated 2022/08/24

I just used my Arduino uno with Micky's software modified, compile fine, I don't have my PCA 9685 here so I can't use it here at the farm, but I know it works

Most Arduino have a SDA or SCL

Remember - Nothing would move until I added a separate 5 to 7.5 v power supply, I use on the PCA 9685 above

Removed as no longer correct

did you get it to work yet?

I have not tried it yet I need to pull the Lattepanda out of my V1 head first and setup some type of test bed for it.  Space is a bit of an issue for me at the moment.

Sounds good,

I just tested the Arduino uno (with the Arduino code) and the PCA9685 with just 8 servos, as you can see, it works well
