3X SPI Reader Mini SD Memory Card TF Memory Card Shield Module for Arduino

Material: PCB, metal Size: 4.1x 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 3.3 V level converter chip, mini SD card supply. A level conversion circuit: mini SD card in the direction of the signals in 3.3 V, the miniSD card in the direction of the control interface MISO converted signal also 3.3V, can universal AVR minicontroller system read the signal. mini SD card port: Since the bomb deck for easy card insertion and removal. positioning holes: 4 M2 screws positioning hole diameter of 2.2 mm, the module is easy to install positioning in order to achieve inter-module combination. Package includes: 3x Micor SD TF modules Only the above package content, other products are not included.
