KEYESTUDIO 16-Channel 12-bit Servo Motor Driver Board I2C Interface for Arduino R3 Controller

I got this for a robotic arm project that I am working on and it works well. It makes connecting many servos to a microcontroller much easier. It uses the IIC protocol for communications so it is a bit different to code for when you are used to coding and wiring each individual servo to the microcontroller itself, but once you get one servo working, the rest is a breeze. I would definitely recommend this item for more advanced projects. It saves a bunch of time and hassle in the long run.

Awesome thank you

A little bit of a learning curve, but once you get used to the library then it works fine. Not very clear which library should be used so I had to do some extra research to find out that the adafruit library was the right one.

Worked well for a robotic arm project. I used it with MG996R servo motors.

Really well designed board with huge potential. Layout is simple. Easy to use, even for beginners. Well packaged. Will be purchasing more for my next few projects.

Haven't built the project, yet, but I'll probably have some Keystudio proto boards elsewhere in the project, so having this servo board will be perfect.

Fits on. Board perfectly

If anyone is having trouble getting this to work, the driver comes with an unpopulated spot for an electrolytic capacitor. The value you need is roughly 100uf x the amount of servos you have connected. If you're using 4 servos then a 470uf 6.3v electrolytic capacitor will do the job. 10, 1000uf 6.3v, you get the idea. You can go over in both values, 4 servos with a 1000uf 16v electrolytic capacitor, for example, but it will struggle if the capacitance is too low, and will ruin the capacitor if you use a voltage lower than 6.3v. Other than that issue, the board works fine and suits my needs. But instructions detailing that need should be included with the board for beginners.

このシールドをunoに重ねてもさらにピンが拡張接続できる構造は良いのですが、 接触圧が弱く接続がスカスカの箇所があり、拡張ピンから信号を取り出した時にノイズが乗ってしまいがちでした。 とりあえずピンをテープで固定して使用しています。今後機能安定のため信号線は半田付けにしなければならないかもしれません。

Produit parfait et conforme à la description

I have two now. This is a shield, so fits neatly on the arduino (others require cabled connections). We’ll packaged, prompt delivery.

Parfait pour mon projet

Works great on my Uno
