This is a unique board recommended by a SparkFun customer. When playing with microSD, you sometimes need to view what the SPI traffic is doing, whether for hacking or debugging. The SparkFun microSD Sniffer allows you to hook up an external device, such as a logic analyzer or microcontroller, to view what signals are being passed back and forth. Insert one side into a regular uSD socket and a uSD card into the on-board socket, simple as that.
All necessary pins are broken out to an 8-pin 0.1" pitch header.
This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

I ordered two (2) TOL-09419 (Sparkfun microSD Sniffer). Both units do not work properly. The edge connector that connects to the host microSD has the following problem: 1. The connector does not engage and does not latch on to the host microSD properly. It disengages easily. The hook on the edge connector of the Sniffer is not shaped or sized properly to latch with the host microSD. 2. The edge connector itself is very thin, It would not make proper connections to the terminal connector of the host microSD. If it did make connections contact with the host because of problem #1, connection is very intermittent.
These problems have been verified by one of your engineers. The implementation could be improve greatly.
I rate your support service 5-stars. They acknowledge that it could not be fixed right away and refunded the full cost to my account.
Good quality, works as described
You must shim liberally to make it work.
Makes tinkering with microSD easy.
Electrically, it works great, no problems. Mechanically, it could be better--
1- It doesn't latch into the card slot. The milling to make the "hook" part of the pcb is not very good. I have to wrap some tape around everything to keep it from popping out all the time.
2- It's too wide for my application. The usb port for my device is right next to the card slot. I had to cut the molding off the cable and shave the pcb a little so that I could plug both in at the same time.
The pads don't align in the socket and it doesn't latch properly.
Sorry to hear you weren't satisfied. I have arranged a refund for you. Have a nice day!
Very practical, the right size for use and good looking
Worked out perfectly for my generic Allwinner based tablet. I was experimenting with a custom recovery and got to the point where I needed more debug information. I ordered this breakout board, soldered on a header, and connected it up to my SparkFun USB TTY serial device. It was amazing and I was so glad when it worked right away. I was able to get the tablet into fastboot and fixed my problem.
