Treedix 10pcs Module Mini TF Card Read and Write Micro SD Card SPI Interface Compatible with Arduino

Features:· This module (MicroSD Card Adapter) is a Micro SD card reading and writing module. Through the file system and SPI interface driver, the microcontroller system can read and write files in the MicroSD card. The SD card library that comes with the IDE can complete the initialization and reading and writing of the card.· Onboard level conversion circuit, that is, the interface level can be 5V or 3.3V.· The power supply is 4.5V~5.5V, and the onboard 3.3V voltage regulator circuit.· Use this SD card module to easily, cost-effectively expand the Arduino storage space. The SD card module interface is a standard SPI interface, which can easily communicate with the Arduino SPI protocol.· Positioning holes: The module has 4 M2 screw positioning holes for easy installation, so as to realize the combination between modules. Specification: 1. 6 pins (GND, VCC, MISO, MOSI, SCK, CS), GND is ground, VCC is power supply, MISO, MOSI, SCK are SPI bus, CS is chip selection signal pin 2. 3.3V
