The level conversion circuit board that can interface level is 5V or 3.3V
Communication interface is a standard SPI interface
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 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,
Micro SD card toward the direction of the control interface MISO signal is also
converted to 3.3V, general AVR micro controller system can read the signal;
mounting holes: 4 M2 screws positioning hole diameter of 2.2mm, easy to
install positioning, to achieve inter-module combination.
