Modul micro SD card reader and writer ini memungkinkan microcontroller untuk membaca dan menuliskan data ke micro SD card layaknya seperti sebuah hand phone. Modul ini menggunakan standar komunikasi SPI interface.
Fitur : Supports micro SD card (<=2G), micro SDHC card (<=32G) (high-speed card) Level conversion circuit board that can interface level is 5V or 3.3V Power supply is 4.5V ~ 5.5V, 3.3V voltage regulator circuit board communication interface is a standard SPI interface 4 M2 screw positioning holes for easy installation
Control Interface : A total of six pins (GND, VCC, MISO, MOSI, SCK, CS), GND to ground, VCC is the power supply, MISO, MOSI, SCK is the SPI bus, CS is the chip select signal pin.
Level conversion circuit: Micro SD card into the direction of signals into 3.3V, MicroSD card toward the direction of the control interface MISO signal is also converted to 3.3V, general AVR microcontroller system can read the signal
Positioning holes is four M2 screws positioning hole diameter of 2.2mm, the module is easy to install positioning, to achieve inter-module combination.
Perhatian : Barang sudah di QC oleh pabrik. Jadi tidak kami test terlebih dahulu. Mohon perhatikan pemasangan dan tegangan jangan melebihi batas dan jangan terbalik. No retur dan no komplain. Membeli berarti menyetujui.
