Description:<br />This module is compatible Arduino Shield interface. Directly plug in to the Arduino UNO motherboard， Arduino MEGA 2560 or other motherboard to extend space of data storage. Easily finish reading / writing operation via the file system. Widely used in digital phone albums， sensor long time / high frequency adopting system， text reader etc needs large amount of data storage; SPI interface: MOSI， MISO， SCK these three signal pins from ICSP interface<br /><br />  Main Features: <br />Standard Arduino expansion board interface<br />Compatible with Arduino UNO， Arduino MEGA2560 and other motherboards<br />On-board level conversion circuit， that is the interface voltage is 5V or 3.3V<br />Communication interface is standard SPI， supports SD / TF card SPI analog communication<br />Supports SD / SDHC / Micro SD / Micro SDHC (Please combined using with TF card adapter)<br />On-board 3.3V regulator circuit<br />Supports SD card up to 32GB<br />Supports Micro SD / TF card up to 2GB<br />Supports micro SDHC card up to 32GB<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% 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: SD card breakout board                                                  <br />                        Compatibility: Ardunio， Arduino Mega 2560                                                	<br />Connectivity<br />	 Connectors: ICSP， SPI                                                	<br />Electronic Components<br />	 Input Voltage: 4.5-5.5V                                                  <br />                        Operating Voltage: 3.3V                                                	<br />Weight and Size<br />	 Product Weight: 20 g                                                  <br />                        Package Weight: 0.070 kg                                                  <br />                        Product Size(L x W x H): 6.9 x 5.4 x 2.4 cm / 2.7 x 2.1 x 0.9 inches                                                  <br />                        Package Size(L x W x H): 8.0 x 6.0 x 4.0 cm                                                	<br />Package Contents<br />	 Package Contents: 1 x SD Card Board， 1 x User Manual                                                	<br /><br /><br /><br />                                                <br />
