Description: The Arduino Mega now has its very own prototyping shield! The SparkFun MegaShield mates with the Arduino Mega board and gives the user a prototyping area, two general LEDs, and, most important of all, the Arduino Mega reset switch is brought to the top level. The shield also works with our small breadboards if you don’t want to solder to the prototyping area.
This comes in kit form and must be soldered together by the end user. Please note - we do not ship assembly instructions! All soldering is through-hole (relatively easy) but always check your component orientation before soldering!

The headers didn’t fit into the PCB until the sides were sanded down. Once that was done, the shield would get stuck in the Arduino and took a lot of careful pulling to release it. I had planned on using this to quickly attach and detach the circuit from the Arduino, so this product was completely unusable.

potential risk of shorting over usb jack and no pads to connect to arduino header pins…not sure what the point is without that…
Thanks for the feedback. I’ll pass this along to our Engineers for consideration if this item comes up for revision.

-Includes a green and red LED, but doesn’t label which is which and they are super-bright… a bit overkill for status lights. -5 v bus runs right over the USB connector, creating a shorting hazard. With proto board seated fully, this section of the board can’t be used anyway as it is touching the USB connector. -Kit includes only 8 pin headers. One must be cut to length for the 6 pin spot (yet a 6 pin header is available in the Uno kit) and the other extra must be cannibalized to make two 2-pin connectors to cap off the large block on the end of the board. Not hard if you have good small side-cutters, but I cringe to think of using anything larger. -No breakouts for the headers; either need to make connections through the top or solder on the bottom. This would be nice for at least the main headers along the side, but who knows… maybe that would cost too much space.
Overall it works, but there are pitfalls.
I appreciate Sparkfun releasing the Eagle files as an Open Source resource. However, it appears that the names of the pads are in some cases reversed. This is very confusing. The symbolic names of the pads are in the opposite order than the silk screen. Since nothing is wired to these on this board, it doesn’t matter, but if you are using this as base for designing your own PCB, it is very confusing.
The board is valuable but as another reviewer pointed out, you are going to end up with wires going into the female headers anyway. I am a beginner, but as others have suggested, it might be better to do pure breadboarding and then uses this design as the basis for a shield in the form of a custom PCB.
