I have two Arduinos connected to a RPi. Each of the Arduinos has a single PCA9685 connected via SDL/SDA cable.
Do I need to have a different ID for each PCA9685 (set up in the individual sketch as well)?

Hi Toni,
Welcome back!!
If 1 Arduino and 1 PCA9685 are the only devices connected on each bus then you’ll be fine to leave the addresses (ID’s) unchanged.
