Micro SD Card Reader Module

The module of the reader of micro SD cards with goldpin connectors – 2.54 mm pitch. It communicates with the main board via SPI interface. It works with a supply voltage from 3.3 V to 5 V.

Pin Configuration of Micro SD Card Adapter Module

The module contains 6 pins for power and communicating with the controller. The table below describes the pin type and role of each pin on the module.

Sensor maintenance

The SD card communicates using the SPI bus. Most of the microcontrollers, including those used in Arduino, AVR,have hardware to verify this interface.

Specification

• Supply voltage: 4.5 V to 5.5 V
• Integrated voltage regulator: 3.3 V on SPI pins
• Current: about 80mA
• Interface: SPI
• Pins’ pitch: 2.54 mm
• Mounting holes M2: spacing of 38 mm and 20 mm
• Module dimensions: 42 x 24 mm
