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.

Great for beginners
Lots of tutorials online. Took me a bit to understand the power requirements but works well now.
Q: How many boards can I chain together?
A: You can chain up to 62 boards using the address jumpers.
Q: Can I power the servos directly from the Arduino?
A: No, please use an external 5V power supply for the servos to avoid damaging the board.
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?
A: The frequency is adjustable, typically set between 50Hz for servos to 1600Hz for LEDs.
