Adafruit DiMeCard 8 microSD Card Holder [ADA3664]
Mary Poppins had her TARDIS-like carpet bag. 90s kids had their Pokémon card binders. But we have the next best thing: DiMeCard, a super-slim 8-piece microSD storage card. The most useful thing you didn't know you needed.
If you're working with single board computers like the Raspberry Pi or BeagleBone - or maybe you're doing a lot of datalogging or photography work, you know that your microSD cards can multiply like tribbles. And those cards are so small you can't mark them with what they're for. That's where this card-card comes in handy. For IT or photography work, where you need cards on the go, it fits nicely into your purse or wallet. For daily use, you can toss it on your desk, it's large enough it won't get lost or slip underneath your keyboard.
Our customized Adafruit memory card holder features a colorful Raspberry Pi GPIO pinout diagram on one side, and 8 write-able panels to note memory card contents on the other.
Each card is retained by an internal spring clip, so you'll hear and feel a satisfying click when the microSD card is inserted and positively locked in. This is a safe way to avoid any bending strain on the chip inside the memory card. DiMeCard's lanyard hole has already been tested by 'swinging it' at 100 RPM without any cards falling out.
Note: Lanyard and microSD cards not included.
