SD Card Adapter Kit (#32313)

The SD Card Adapter Kit allows you to easily connect an SD Flash Memory Card to your PropellerTM chip
or other microcontroller. This adapter contains the components required for an SPI interface between
the host microcontroller and the SD memory card. The SD Card Adapter Kit includes a card detect switch
which allows you to detect when a memory card is physically present in the socket. It also includes a
switch to determine the read/write status of the inserted card, preventing accidental loss of data.
Mounting holes are available so you can install the adapter in your application.

Assembly Instructions

Step 1:

Locate the SD Card Adapter PCB and
the eight (8) 10 kΩ SMD resistors.
Solder the resistors to the bottom side
of the PCB as shown.

Step 2:

Locate the SD Card Socket and place
it on top of the PCB so that the
registration holes line up and solder it
in place as shown. Be very careful
when soldering the bottom pins on the
socket, which are very close together.
Avoid bridging these by using flux
when soldering.

Step 3 (optional):

If you plan on being able to plug your
SD Card Adapter into a breadboard
you will want to install the 10-pin SIP
header.

Locate the 10-pin SIP header in the kit
and solder it in place as shown.

You could also have soldered in a
ribbon cable or some other
cable/connection.
