This is a breakout for the SOIC version of the 74HC595 shift register IC. Clock in data and latch it to free up IO pins on your micro. All pins from the IC are broken out to standard 0.1" spaced headers. The Serial in and out pins are on opposite sides of the board with the remaining pins carried over so that multiple shift register boards can be chained together.
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.

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Makes experiencing with 74595 SiPo mcuh easier, you don't need to check datasheet all the time whether you made right connections, this chip can be quite confusing at a start, but very handy once you get hold of it. These can be daisy-chained if 8 O/P isn't enough. Good extra about this product is that it's breadboard friendly, only takes quite chunk off from prototyping space, but it's worth it. Underside of pcb is flat, so you can also install it without spacers needed, only there are tracks there so beware of S/C if you place this on metal surface. That said though, pcb quality is great, so S/C won't be issue at least anytime soon
Price is bit pricey if you need only to use this, but makes job easier to use this board
Have been trying for months to get the max 7219 to work in a linear LED display with the Arduino Uno rev 2. But the 7219 is made to be used in a matrix or a 7 segment display. It was thought the fact that the 7219 handled 64 LEDs and the 74HC595 did eight gave the 7219 a great advantage. But breaking the 7219 out created a rat's nest of wiring. Whereas the 74HC595 with Digikey's S5482-ND female 7position right angle connector with the S1111E-07-ND 7 position right angle connector modularized the construction making testing and assembly of a line of 340 LEDs much simpler.
Pin 7 ser-out invert N.C.
They worked as advertised. I received 6 and they all worked. Easy to use and interact with.
As someone who is a little newer to electronics I found the pin out confusing as it the labels on this breakout didnt match the pinout on the 595's in terms of names. I ended up figuring out what was what by using a continuity meter and testing each of the 595's pins to each output. Still easy to use!
The breakout form factor makes soldering the part very easy.
I did receive the boards in a short amount of time, but I did actually pay for that. The boards were in good shape, but I did find that the only tutorial was for the parallel in and serial out. I did attempt to put together all examples of how to wire them up with no success. So, I did email SparkFun. Their response was prompt, but they did not have any solution. They did acknowledge that there wasn't a tutorial for this board and could not provide any assistance. I've use many of their boards with no issues, but for those boards, there were many tutorials. Unfortunately, there aren't many tutorials out on the web for this board and SparkFun doesn't have one either. At the least, I was surprised to not get any further assistance from SparkFun. This is very disappointing. If you check out the board's page at the time of this review, you will find a "Get Started With The Shift Register Guide" where it discusses shift registers in general, but the only wiring discussion/example is for the other board with slightly different pins. I am abandoning the SparkFun board and using the basic chip.
Thank you for your review. I think you might be confused about how the breakout is supposed to work though. Hopefully the data below will clear things up for you. SER_IN is the same as pin 14 on the IC L_Clock is the same as 12 on the IC Clock is the same as pin 11 on the IC /OE is the same as pin 13 on the IC /Reset is the same as pin 10 on the IC and SER_OUT is the same as pin 9 on the IC
The board is laid out with the outputs on the bottom edge of the board and power and inputs are on each side so that you can daisy chain more than one board together.
