Easy to use with Python libraries
Setting this up was incredibly easy. The Adafruit library works perfectly out of the box. It's a great learning tool for understanding PWM and I2C communication.

Solid performance
Does exactly what it says on the tin. The screw terminals are secure, and the board feels sturdy. Only wish it came with a detailed pinout diagram printed on the back.

Perfect for robotic arms
This board works flawlessly with my Raspberry Pi 4 project. The I2C interface saves so many GPIO pins, and controlling 16 servos simultaneously is smooth. Highly recommended for robotics enthusiasts.

Reliable and stable
I've been running this for weeks in an automated camera rig. No dropped frames or jittery movements. The separate power input for servos is a crucial feature that prevents brownouts.

Great value, minor soldering needed
The board functions exactly as described. You need to solder the headers yourself if you want to stack it directly on the Pi, but the instructions are clear. Good build quality for the price.

Excellent for multi-servo projects
Before this, I was struggling with software PWM on multiple pins. This hardware solution is precise and reliable. Stacking two boards to get 32 channels was seamless.
Q: Is this compatible with the Raspberry Pi 5?
A: Yes, it is fully compatible with the Raspberry Pi 5, as well as the 4, 3, and Zero models, provided you have the correct 40-pin GPIO header configuration.
Q: Do I need to install specific drivers?
A: No specific drivers are needed beyond enabling the I2C interface in raspi-config. You can use popular Python libraries like Adafruit_CircuitPython_PCA9685 to control the board immediately.
Q: What type of servos does this support?
A: This module supports standard 5V hobby servos that accept PWM control signals. It is not designed for high-voltage industrial servos or continuous rotation motors without specific modifications.
Q: Can this board be powered directly from the Raspberry Pi GPIO?
A: While the logic level is 5V compatible, we strongly recommend using an external 5V-9V power source connected to the servo power terminal for driving servos to avoid damaging the Pi due to high current draw.
Q: How many of these boards can I connect to one Raspberry Pi?
A: You can chain up to 62 boards on a single I2C bus by configuring different I2C addresses via the solder jumpers on the back of the board.
