This is the SparkFun RJ45 MagJack Breakout, a simple board that will provide you with a way to put an ethernet port into your breadboard. The SparkFun RJ45 MagJack Breakout is the same one found in our very own mbed Starter Kit and breaks out each pin from the ethernet jack. This rev of the breakout is equipped with the RJ45 MagJack connector already soldered to the board which mean you no longer need to solder the connector to the board yourself or worrying about buying them separately!
The on-board RJ45 ethernet jack has a built in transformer (magnetics), status LEDs, and shielding all for better reliability when you use it. As stated before, each pin from the RJ45 MagJack has been broken out, including: P1-P8 (Pins 1-8), Y+ (Yellow LED Positive), Y- (Yellow LED Negative), G+ (Green LED Positive), G- (Green LED Negative), and SH (Shield).
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 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.

This product is a single RJ45 jack breakout PCB. I will not comment on its MagJack properties - including the transformers which I presume are for Power over Ethernet applications. I did not buy it for that feature which others may find useful. I wanted a small RJ45 breakout PCB that I could mount and that would allow me access to the 8 standard RJ45 pins. This product achieves smallness and offers access to each of these 8 primary RJ45 pins. That satisfied my use. it has other solder pins which I assume are for the transformer and LEDs and that may interest others with more sophisticated needs.
What I like about this product:
2. 2 clearance holes for mounting this PCB
3. Breakout solder pad access to all internal RJ45 jack pins.
4. well labeled.
5. attractive red PCB color. (just kidding. don't care about the color). 6. Build quality looks good.
I looked around and this was one of the smallest RJ45 breakout PCBs I found. So, good for them. I will buy them for my application.
I would like to see them make PCBs with 2, 3, and 4 RJ45 jacks with solder pad breakouts in which the RJ45 jacks are NOT in parallel but in which each Jack is individually addressable. That I could not yet find.
Overall, seems like a good example of a RJ45 breakout PCB.

Pin 1 & 2 are shorted. I'm not sure if I'm just misunderstanding the product, but I wanted a simple way to connect to the pinout of a cat5 cable. You can not achieve that with this product.
