SongHe 16 Channel PWM/Servo Driver IIC interface-PCA9685 for arduino or Raspberry pi Shield Module servo Shield (2pcs)

This is perfect for controlling most common servos, but know what you're getting.It is NOT a servo DRIVER. This is a servo controller. This is just a board that you can configure with I2C commands to output PWM signals at certain frequencies and duty cycles. It does not actually convert or regulate any input voltages. Whatever voltage you put on VCC is going to the PWM controller and whatever you put on the screw-down terminal block is going to the servos.This board is based off of the PCA9685 LED controller. It works perfectly for my servos (MG996R and SPT5525LV-360). The modulation frequency range is actually 24Hz to 1526Hz.The output frequency is not high precision or high accuracy. My servo needed 330Hz, but 339 Hz was the closest setting because of the precision limits. Luckily the loose accuracy of the device resulted in the output actually being 328 Hz. The duty cycle on the other hand is usually within 0.1% of the desired value.Overall, it's done the job pretty well. No problems so far.

Fixed a board in ACNC by replacing it after it burnt the original board. Working well with this in it

I ordered these and they worked as a drop-in replacement for the Adafruit board driving the same chip. It worked flawlessly with no code changes required. The Adafruit library worked great. I like the header configuration as well as the mounting screws, as it provides alot of options for installation.For the price, these are great boards.

I'm only running small RC steppers "Servo" Motors. And I can't speak to the longevity of the drivers. But working is working. And I've got it paired with a Pi pico, so the hole thing is very small and lightweight

This product arrived on time and seems to work just fine. It was a good price and I am using it to control 13 servo motors through an Arduino. Good product.
