mikroElektronika microSD Click User manual

1. Introduction
Need more additional memory? We’ve got
just the thing for you. microSD Click is an
accessory board in mikroBus™form factor. It
features a microSD card slot for microSD cards
used as a mass storage media for portable
devices. Industry standard SPI interface
ensures simple communication at high data
rates. Use it for reading or storing data like
music, text les, videos and more. Board is
designed to use 3.3V power supply only.
On board ferrite voltage supply lter ensures
stable operation.
Once you have soldered the headers your
board is ready to be placed into desired
mikroBUS™ socket. Make sure to align the
cut in the lower-right part of the board
with the markings on the silkscreen at the
mikroBUS™ socket. If all the pins are aligned
correctly, push the board all the way
into the socket.

4. Using microSD Cards
Board contains the slot for standard
microSD cards. Once power is turned on,
power LED will indicate that board is in
operation. Data is read and written to the
card using industry standard SPI interface.
Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder the
pins carefully.
Turn the board upside down, so that
bottom side is facing you upwards. Place
shorter parts of the header pins in the
both soldering pad locations.
