Grove - Servo is a bonus product for Grove lovers. We regulated the three-wire servo into a Grove standard connecter. You can plug and play it as a typical Grove module now, without jumper wires clutter. For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your using of the product.
But if you feel like a proto servo, please check out EMAX 9g ES08A High Sensitive Mini Servo. They are the same model, both of good quality and burden-free price.
Kit include: Servos Horns x3 & Screw x3
