Description: The SparkFun Level Shifting microSD Breakout is quite similar to the SparkFun microSD Transflash Breakout, but with the included level shifting hardware, this board allows you to utilize a microSD card at Arduino’s SD library’s top speed on a 5V system. With this small breakout board, that is not much bigger than your fingernail, adding mass storage to your project will never be easier.
With the additional feature of being 3.0V to 5.0V tolerant for ease of use, discrete level shifting is no longer required. This breakout is also a bit unique in that it level translates all of its outputs back to the level of the hardware it’s connected to.

It arrived really quickly, the only thing I had to get some pins for trying it, I thought they were included. In any case, they are always really cheap in your habitual Chinese supplier.
I used this on my AVC vehicle to figure out the length of straights and direction of turns, as well as figure out how sensor data looks while the car is on the track.
This breakout plus Sparkfun’s SD arduino library makes it super quick and easy to keep logs.
A couple of things to watch out for: If you had been using your uSD card in a Raspberry Pi, the SD library won’t know how to handle it. Reformat the card and you’ll be fine. Small writes normally take between 10 and 20 microseconds on my card (using a teensy 3.2), but occasionally hundreds of milliseconds.
Bad connection between the holder and the card causing intermittent errors.
Sorry to hear you’re having problems with this. If you contact our tech support team, they should be able to help you resolve it.
Exactly what I needed for a quick and permanent prototype. The included level-shifter on the bottom of the board makes it compatible with both 3V and 5V circuits.
