HiLetgo 2pcs PCA9685 16 Channel 12-Bit PWM Servo Motor Driver IIC Module for Arduino Robot

I have an Arduino project that requires six servos. This 16 channle servo driver is amazing. It worked flawlessly out of the box. My difficulty was that the driver uses I2C communications and that made it difficult to use the Arduino as a master since my I2C network has the Arduino as a slave. And it then became a tradeoff of using six of the Arduino outputs to drive the servos direcly, or continue with a modified I2C network and have ten channels not used. It would be nice to have this product available in an eight channel version. But, as designed, this is an amazing product. Highly recommended.

Delivered on time, packaged well. Tested and works as intended. Great value for the money. Will recommend. Needed this for a robot project.

Prompt delivery, product exactly as described. Will use this vender again.

I’m running an Arduino project that needs six servos, and this 16-channel driver worked flawlessly right out of the box. Super easy to set up and seriously impressive. The only hiccup was that it runs on I2C, and in my setup, the Arduino is a slave on the I2C network—so getting it to play nice meant either reworking the network or using six Arduino outputs directly. Kinda wish there was an 8-channel version to avoid wasting the extra ports, but honestly, this thing is rock solid as-is. Highly recommend it if you need reliable servo control.

These are cool motor drivers; they're built with fairly decent quality. You can control anything with a PWM input too, like LEDs. You can also cascade these to control over 900 servos, lol! However, some of the pins came bent; probably got bent out of shape during shipping, although reshaping them isn't too tricky with needle nose pliers, and they function.I have 2 6v servos controlled through a PCA9685 using a Arduino Uno R3 as a platform for controlling the servos with 2 10k potentiometers. Pretty neat, although there is zero documentation that come with these, so unless you've already got some information about using these you might be in a situation where you'll need to do research to supplement the lack of documentation. Luckily the Arduino community provides essential hidden knowledge to the public regarding electronics, usually free of charge, and helps to demystify these useful electronic modules.I can't imagine why a manufacturer wouldn't want an informed public to know of the usefulness of the product they're producing, which is to be sold, but these aren't too hard to work with, and looking into how to do interesting things with these isn't too tough either with all the open source projects out there that call for using these.

Good product, good seller

FYI, 3mm mounting screws will not work on these boards. Go buy some 2.5mm screws if you don't have any. The mounting holes have metal sleeves, so "drilling them out" might damage the board.Search for "Adafruit PCA9685 16-Channel Servo Driver" for some excellent hookup instructions.

Both drivers don’t work.
