Hi, everyone!
Am I understand correctly that Raspberry Pi 4B board has 28 GPIO pins (0-27), thus, it allows us to control 28 servos simulatenously without using any additional hats ?
Of course, assuming that power supply to servos is external and there is a shared ground.
Bachground info: I am working on robotics projects and at first I was planning to use control 20+ servos via (one or two) PCA9685 connected to 4b board. But then I realised that there might not be any need for that if I can do it directly on the 4b board.
Also, would there be any downsides connecting 20+ servos directly to RPi 4B as opposed to doing it via PCA9685 ?
Thanks in advance for any comment!
