Teyleten Robot PCA9685 16 Channel 12 bit PWM Servo Motor Driver I2C IIC Module for MG90S SG90 MG995 Compatible with Arduino Raspberry Pi (2pcs)

Using this to control a bunch of servo blast gates in a dust collection system. It works well.

I was going to use a 9685 shield but it made the stack too high so went with the module, made my life a lot easier

Below is the code for I2C from python running on Le Potato. The servo numbering starts at zero not one. The rest of the board is amazing. everything is clearly marked and the colored PWM channels are very helpful. import time from adafruit_motor import servo from adafruit_pca9685 import PCA9685 from adafruit_extended_bus import ExtendedI2C as I2C i2c = I2C(1) pca = PCA9685(i2c) pca.frequency = 60 servo1 = servo.Servo(pca.channels[0]) for i in range(180): servo1.angle = 180 - i time.sleep(0.03)

Works as intended. Pins got bent in transit which made attaching the servo wires slightly difficult. Functionally, no issues once the pins were straightened, but it could have been packaged a little better so that didn’t have to be dealt with. Overall, good value for the money.

great, fully functional easy to use, long lasting, great for price, they are small and don't have a loud presence, very durable and can take whatever i throw at them, quiet efficient presence

Works as expected and build in good quality. This ships without any kind of documentation or code so you have to look up the chip programming yourself. Only downside is the oscillator is not accurate so you have to measure it.

One of them gave off a poof of smoke before it failed so I threw the other one away and went back to using another type of servo controller.

Powered in, and Grounded on the Green Terminal, When I plugged in a servo, the power would then go out the 3.3 Pin. I fried two PI's because of this. Do not buy. The circuits are not separate.

The items were exactly what I needed for my project
