Main Features:<br />● L3G4200D + ADXL345 + HMC5883L + BMP085 chip<br />● Communication: IIC protocol<br />● Installation hole: 3 mm<br />● Power supply: 3V - 5V<br /><br /> 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 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 />	 Compatibility: Ardunio                                                	<br />Weight and Size<br />	 Product Weight: 0.038 kg                                                  <br />                        Package Weight: 0.09 kg                                                  <br />                        Product Size(L x W x H): 2.8 x 1.8 x 0.3 cm / 1.1 x 0.71 x 0.12 inches                                                  <br />                        Package Size(L x W x H): 20 x 14 x 2 cm                                                	<br />Package Contents<br />	 Package Contents: 1 x 9-Axis Module                                                	<br /><br /><br /><br />                                                <br />
