Data logging micro SD TF card reader board shield module SPI Arduino, Raspberry PI
Ideal for data
logging for any Arduino, Raspberry, PIC or any other microcontroller projects.
Module features are
as follows:
- Support Micro SD/SDHC cards
- Standard SPI communication interface
- power supply is 4.5-5.5V, 3.3V voltage regulator
circuit board
- 4 M2 screw positioning holes (2.2mm) for easy
installation
Connection instruction:
Pins: GND, VCC, MISO, MOSI, CLK, CS; GND to ground,
VCC is the power supply, MISO, MOSI, SCK are 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.
