Perfect for robot arms
Worked flawlessly with my Arduino Uno. The library is easy to use and the servos move smoothly.

Good value
Does what it says. Wish the terminal blocks were included for power input, but otherwise solid.

Smooth servo control
No jitter on my servos. I2C communication is stable even with long wires.

Q: Is a library available for Python?
A: Yes, there are several Adafruit compatible libraries available for Raspberry Pi.
Q: Does this support continuous rotation servos?
A: Yes, it works with standard and continuous rotation servos.
Q: What is the PWM frequency range?
