But for those who fancy experimenting with the format it’s still possible to make a basic card reader using LEDs and light sensors, as [Nino Ivanov] has done using an Arduino Uno as the brains.

A maker developer has squeezed an Arduino onto an SD card. He was inspired by Intel’s Edison compute module and he tried to go one better. The result is the SDuino, an ATMega328P processor-based ...

You may need to format an SD card or micro SD card for several reasons on your Mac, whether it be for your smartphone, Raspberry Pi mini PC, Arduino project, digital camera or games console.

There’s also an SD card thrown in for good measure, making this one of the best tracking and data logging shields for the Arduino.
