Arduino OPENJUMPER TF Card Read Write Storage Module

Arduino OPENJUMPER TF Card Read Write Storage Module

Description:     
- The TF card reader module is an interactive media device to store the most commonly used memory modules, using the SPI interface. Modules can be connected via the DuPont line sensor expansion board, preparation of the corresponding program can achieve a variety of sensors (such as temperature and humidity sensor, light sensor, GPS, etc.) data logging function, TF card data read by the reader, it can easily be analyzed using the module and with two LED lights to indicate TF card working condition.     
 
Specifications:     
- the working voltage: 3.3V-5V     
- means of communication: SPI     
- TF deck forms: from the pop-up     
- Size: 25X35mm     
 
Pin definition:     
- CD: card detection / high (no card) / low (card inserted)     
- CS: TF card selection / low (selected by default)     
- MOSI: SPI data input / high     
- MISO: SPI data output / high     
- SCK: SPI clock / low     
- VCC: Power supply positive terminal / NA     
- GND: power supply negative terminal / NA     
 
Indicator Description:     
- when the card is not connected to the power supply when an LED lit, indicates that the module power supply is normal.     
- after inserting the card lit the LED starts flash, indicating TF card has been inserted
 - another LED flashes is communicating.     
 
Wiring:     
- CD: the user can be used to detect whether the card is inserted, do not use the time to connect (routine does not use)     
- CS: TF card selected, the routine must be connected to the 4th leg (in the absence of other SPI devices without connection)     
- MOSI: connect to MOSI port at UNO and pin-compatible board for the 11th     
- MISO: MISO is connected to the mouth, in the UNO and the board for the 12th pin compatible     
- SCK: connect to SCLK port in UNO and pin-compatible board for the 13th     
- VCC: Power supply positive terminal connected to 5V     
- GND: power supply negative terminal connected to the negative power supply, GND
