The microSDHC card is the smallest consumer-focused flash memory card in use today. It’s a variation of the standard SDHC card (short for Secure Digital High Capacity) and uses a similar set of electrical connections. That makes it possible to use microSD cards in standard SD card slots with the use of an adapter. MicroSD was introduced as a smaller alternative for portable electronics.
There is space for up to 32GB on a microSDHC memory card. Usually you have the choice of a card with 16 or 32GB. These memory cards are most commonly seen in smartphones and tablets. But they also work with action cameras, drones, and 360-degree cameras. What you record with it depends on the write and read speed of the card, but they’re usually videos of HD quality, for example.
