SD Card

Secure Digital, officially abbreviated as SD, is a proprietary, non-volatile, flash memory card format the SD Association (SDA) developed for use in portable devices. Because of their small physical dimensions, SD cards became widely used in many consumer electronic devices, such as Arduino, digital cameras, camcorders, video game consoles, mobile phones, action cameras such as the GoPro Hero series, and camera drones.
