This simple board breaks out the pins of a microSD card connector to a 0.1″ pin spacing that is compatible with standard perfboards, solderless breadboards, and 0.1 connectors.

MicroSD memory cards (originally known as TransFlash) provide a compact and inexpensive way to add gigabytes of non-volatile storage to a project. All SD cards support communication over the SPI (Serial Peripheral Interface) bus, making it straightforward to interface one of these cards with an SPI-capable microcontroller.
