this is a well made little board with a good socket on it. i have bought several different SD card boards for Arduino and this is the best so far. if you have room for a standard sized card holder, this is the best deal. it has pins for both 5 volt and 3.3 volt (after the on board v regulator) whereas other boards require you to stick 3.3 volts onto a circuit board trace or tiny surface mount tab. the socket is the push push type and works reliably. if you need a micro sized card holder you will have to spend a lot more money to get a good one. the cheap ones are unreliable. not too much to one of these boards but the details are critical if you want reliability.

Received this SD reader today. It arrived in the mail in good condition. Hooked it up to my Ardunio and plug the USB cable in. I notice the power LED on the Arduion was off. Check all my connections and everything was good. power the Ardunio up again and still no power. So I disconnected the SD reader and power the Ardunio up again. The Ardunion powered up and everything is fine. I proceeded to check the SD reader with a Ohm meter. Found a dead short between ground and 5V and CS pin and ground. I inspected the solder joints for the header and found a very poor soldering job. Too bad, the rest of the card is constructed well. Contacted the seller and hopefully get a replacement.

First off, this breakout is constructed well as far as the card mechanism itself. There is a 5v to 3.3v regulator on the pcb, the resistors present on the SPI appear to be used as voltage dividers, this is probably why it doesn't want to work with all cards due to the rise and fall causing jitter (noise).

A breakout with a level shifter chip like the TI HC4050M makes for a better and more stable choice but you will pay 2 to 3 times this price for the stability it provides.

Rather finicky board with no documentaiton. I spent about an hour trying different wiring combinations that I found around the web. Not sure if all units are assembled consistently. For me I finally got it to work with this layout:
3.3v and 5v connected to my Arduino Uno R3 along with both grounds.
CS to PIN 10
MOSI to PIN 11
SCK to PIN 13
MISO to PIN 12

The example sketch with Arduino IDE (CardInfo) was able to see the card. I needed to change cardsense to PIN 10 in the sketch. Also, only the pins closest to the card worked. The outer pins on the board did nothing.

I give it 5 stars on price, but 1 (no zero) star for quality, 4 stars for making it available. You have to know a bit about electronics to make it go, even though it is an incredibly simple design. And that is the source of all the problems people have with it.

While a lot of comments are about level shifting (check out Dennis Spanogle's comments!) I'm pretty sure that the electrical noise is the problem. Keep you line lengths shore and use (make) twisted pairs (braided trios).

It is fragile. OK, I'm abusive to my projects because I try to make things that will last. I've had mine exactly two days and I broke one of the leads to the SD holder. (How did I figure that out? There are four resistors, three capacitors and a very robust voltage regulator ... these are not easily fried. it was a broken trace or lead.) Tiny little buggers and when I tried to fix it I broke a half dozen more. Not only are the leads fragile, but the pc board itself is fragile. When I removed the header, I buggered the connection to the SCK line. (The plating of the plated through hole came out with the pin.)

Yet I was still able to fix it. I soldered wire-wrap wires to the contacts of a micro-SD to SD adapter, then soldered these to the appropriate places on the board. (Care must be take to not melt the adapter. Also note that contact 4 of the adapter is soldered to pads 4 and 5 of the board)

So I love the cheap price: There is no way I could have bought all the individual parts that cheap. It included is a board to which everything is mounted. Bottom line, if you can't do what I did, spend the the money to buy one from a company that would send you a replacement if it didn't work first time out of the box.

(How many stars should I give it? My rating is what it is because I would like you to know into what you are getting.)

Direct from China. Took almost a month to get it (was warned). Not a problem, arrived in time for the holiday.

Good for the price. A little confusion exists and not well described so here goes:
This card reader has a 3.3v regulator on chip. Supply 5 Volts to the 5 Volt pin and 3.3 volts is supplied to the SD Card and to the 3.3volt pin. You do not need to supply 3.3 volts.
All lines except CS have a 10k pull up resistor connected to the 3.3v on-chip regulator. To use with 5 Volt Arduino::
Connect 5 volts to the 5 volt line.
Connect a diode to each signal line except CS. The cathode should be connected to Arduino digital line. This lets the Arduino digital output pull down the card's line but prevents the Arduino from forcing 5 volts to the card's signal line. The on-board pull up resistor will pull the card's line high to 3.3 volts. ( Arduino pin ----|<--- Card reader pin )
For the CS line: connect a pull up resistor from the CS line to the 3.3 volt pin on the cards pin (connected to the onboard 3.3V regulator. 10K should work. Then connect a diode from the CS line to the Arduino digital pin as above.
This is easier than using a level converter.
