## Description

This is the cutest little microSD card reader/writer - but don't be fooled by its adorableness! It's wicked fast and we've tested these with up to 256 GB SDXC cards. Simply slide the card into the edge and plug it into your computer. No drivers are required, it shows up as a standard 'Mass Storage' device under any OS. You can swap cards while the USB port is kept plugged in. 

Comes with a handy little cord so you can attach it to your datalogger project. Also has a little plastic cover for the USB A connector part so it won't short against nearby electronics. 

Max read speed is 16 MB/sec, max write speed is 6 MB/sec - most microSD cards are not this fast so the bottleneck will be the card, not the reader 

**Does not come with a microSD card!** we do carry microSD cards in the shop that go great with the reader.
