A32 Micro SD Card module

این ماژول یک کارتخوان SD (با ارتباط SPI از طریق درایور سیستم فایل) است. مشخصات ماژول مطابق زیر است:

Support Micro SD Card (<=2G)- Micro SDHC card (<=32G) (high-speed card)
The 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
Size: 4.1 x 2.4cm

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

3.3V regulator circuit:
LDO regulator output 3.3V as level converter chip- Micro SD card supply

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

Micro SD card connector:
Since the bomb deck for easy card insertion and removal.

Positioning holes:
4 M2 screws positioning hole diameter of 2.2mm- the module is easy to install positioning- to achieve inter-module combination
