Review on 🤖 MakerFocus I2C PWM Servo Motor Driver Module with 16 Channels, 12-bit Resolution, Compatible with Raspberry Pi 4, 3B+, 3B, Zero/Zero W/Zero WH, and Jetson Nano by Thomas Taylor

This servo hat appears to be a copy of Adafruit (aka PCA9685). It's missing at least one critical component - room for a large capacitor to help pull down voltage and absorb surges. Also, 5V on the Pi is shorted to 5V for the servos. Therefore, power surges will most likely kill your Pi, although you could be safe with micro servos. In my case, my standard size servos wrecked my Pi Zero after a few minutes. I spoke to the seller and they are friendly and helpful
