Description
Size: 4.1 x 2.4 cm. 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. 3.3 V regulator circuit: LDO regulator output 3.3 V 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 2.2 mm, the module is easy to install positioning, to achieve inter-module combination. Package includes: 1 x Micor SD TF card module.
