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: Flight controller， GPS receiver module                                                  <br />                        Compatibility: Ardunio                                                 <br />Weight and Size<br />  Package Weight: 0.220 kg                                                  <br />                        Package Size(L x W x H): 10.0 x 8.0 x 7.0 cm                                                 <br />Package Contents<br />  Package Contents: 1 x Flight Controller， 5 x Cable， 1 x GPS Module， 1 x 6-pin Connection Cable (20cm)， 4 x Shielding Plate                                                 <br /><br /><br /><br />                                                <br />
