We carry several data logging products which have microSD sockets on them: OpenLog Artemis and the Qwiic OpenLog to name but two. They're great for logging data to a microSD card, but when it comes to reading the logged data quickly you usually have to pop out the microSD card and plug it into your computer. But what if you're developing an embedded system and you don't want to or aren't able to eject the microSD card. Enter the SparkFun Thing Plus Dual-Port Logging Shield!
