Frequently Asked Questions: <br />Q1. 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% 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: Stepper motor driver module                                                  <br />                        Model: L293D                                                	<br />Electronic Components<br />	 Architecture: Arduino                                                  <br />                        PCB Size: 69 x 53 mm                                                	<br />Weight and Size<br />	 Product Weight: 0.035 kg                                                  <br />                        Package Weight: 0.050 kg                                                  <br />                        Product Size(L x W x H): 6.9 x 5.3 x 2.0 cm/ 2.7 x 2.1 x 0.8 inches                                                  <br />                        Package Size(L x W x H): 9.0 x 7.0 x 3.0 cm                                                	<br />Package Contents<br />	 Package Contents: 1 x Motor Control Shield                                                	<br /><br /><br /><br />                                                <br />
