Good Value Board
Works as expected but you need to solder the headers yourself. Documentation could be clearer.

Perfect for Robot Arms
Used this for a 6-DOF arm and all servos move smoothly. The I2C connection saves so many GPIO pins.

Works but Warm Under Load
The board functions well but gets warm when driving multiple high torque servos. Add a heatsink.

Great for LED Projects
Not just for servos! Used it to drive PWM LEDs for a lighting rig. Very versatile.
5 FAQ
Q: Is this compatible with Raspberry Pi 4?
A: Yes, it works with all Raspberry Pi models featuring GPIO headers. Use the Adafruit library.
Q: Can I control more than 16 servos?
A: Yes, you can stack up to 62 boards using address jumpers for a total of 992 channels.
Q: What is the maximum current per channel?
A: Each channel can handle up to 25mA. For higher current servos, use an external power supply.
Q: What library do you recommend?
A: We recommend the Adafruit PCA9685 library for Arduino and Python examples for Raspberry Pi.
Q: Does it come with header pins?
A: The board typically comes with separate header pins that require soldering for custom setups.
