Why are these called Arduino Compatible? <br />A1. The Arduino group demanded us to remove their logos and rename these products so that they do not lead customers to believe they are the same units sold by Arduino<br />Q2. Are these 100 percent compatible with the normal Arduino's? <br />A2. Yes， they really are completely compatible with normal Arduino's. Build quality looks the same and everything (studio， library， tools， etc) just works<br /><br />    Specifications<br />General<br />	 Type: Motor driver module                                                  <br />                        Model: 021602                                                	<br />Weight and Size<br />	 Product Weight: 17 g                                                  <br />                        Package Weight: 0.08 kg                                                  <br />                        Product Size(L x W x H): 5.6 x 3.2 x 1.1 cm / 2.20 x 1.26 x 0.43 inches                                                  <br />                        Package Size(L x W x H): 20 x 14 x 3 cm                                                	<br />Package Contents<br />	 Package Contents: 1 x Motor Driving Module                                                	<br /><br /><br /><br />                                                <br />
