MicroSD reader 3V SPI/SDIO

Module with microSD card socket. Perfect for adding massive amounts of storage to a microcontroller. Unlike other similar modules, this one can access the SD card using both SPI (one data pin) and SDIO (four data pins, much faster). Please note that this module does NOT have any level shifting or voltage regulator, so it can only be used with 3.3V systems (both supply voltage and signal levels).

Dimensions: 25.4 x 22.8 x 3.5mm
