Unlike the other microcontroller stuffed in an SD card platform — the Electric Imp, [kodera] is, for the most part, respecting the standard pinout for SD cards.

The report of our 1-GB microSD card is shown below as an example. If this experiment is not successful, recheck the hardware and memory card format. If your memory card characteristics are reported in ...

An SD card measures 32 by 24 by 2.1 mm, ... Despite the much smaller size, microSD cards have the same underlying architecture, including the same electrical pinout connections.

Piccolino is being marketed as the world’s first compact Arduino with integrated OLED, WiFi, SD Card together with +32K SRAM. “Piccolino is essentially an Arduino on steroids.

The Arduino Nano itself is the most basic and oldest of the group, and just like its many iterations, it's designed to work primarily with breadboards, making it a great tool for prototyping.
