Main Features:<br />With temperature compensation <br />Communication: IIC / SPI<br />Power supply: DC 3 - 5V<br />Auto offset compensation<br />Max. output frequency: 220Hz <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 />	 Model: CJMCU-85                                                  <br />                        Material: CCL + Element                                                	<br />Weight and Size<br />	 Product Weight: 0.002 kg                                                  <br />                        Package Weight: 0.06 kg                                                  <br />                        Product Size(L x W x H): 1.9 x 1.5 x 0.3 cm / 0.75 x 0.59 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 Sensor Module， 1 x Pin                                                	<br /><br /><br /><br />                                                <br />
