Features: Small soldering area. All pins are brought to the top level. 5V, GND, and Raw pins are exposed as well. SOIC place for IC. The mini breadboard has 170 tie points. Prototype Size:7cm x 5.5cm x 2cm . Mini breadboard size: 4.4 * 3.4 * 1cm . Package Included: 2 * Uno R3 Prototyping Shield Prototype Expansion Board 2 * Mini breadboard

Review: You can never have too many breadboards! - I do a lot of development on Arduinos and STMicroelectronics boards. Both have connectors that align with Arduino Uno V3 pin layouts. As a result, I have a LOT of breadboards laid out in different ways. Honestly, sometimes dealing with a full or half length bread board creates some added complexity, especially if the circuits I'm prototyping don't have many components. Sometimes it's easier to pop one of these on top of whatever dev board I'm using and wire up a quick prototype. I use my workbench for other things and it's easy to drop my dev board into a drawer with its circuits and get back to it another time. When I use a larger breadboard, I have to be careful of the wires connecting it to the dev board. Plus, if I want to see how a particular circuit, like a custom waveform generator, performs with multiple dev boards, it's much easier to pop one of these off and plug it into another dev board. No more disconnecting and reconnecting a few dozen wires just to test a custom wave form! It also reduces the chance of wiring errors going from one dev board to another. I bought 2 packs (4 boards total) and that seems to be plenty for my current projects. Overall rating: 5/5 stars
Review: It's worth the money - The quality I recommended

### ⭐⭐⭐⭐⭐ It's worth the money

The quality I recommended

### ⭐⭐⭐⭐ Fine for my use, but it's outdated and incomplete for the R3.
*by M***N on April 15, 2016*

As noted in another review, the topside pin sockets are inset so this will have to be your topmost shield. I knew this going in so no problem there. There's no passthrough for the ICSP header but there is a place to connect your own since it's in a completely different place on the shield. Again, no problem for me because I don't need it, but this may be a problem for others. The pins aren't very long. I need to stack it on top of a DMX shield so I had to get an extra set of stacking headers (refer to the photo). ... and it's those stacking headers that made me realize ... it's missing pins. The R3 has 3 extra pins (and one extra NC) that are not passed through. On the digital/PWM side, the AD4/SDA and AD5/SCL pins are missing, and on the Power block, it's missing the IOREF and an extra unused pin. Again, for me, none of this matters for my project, but it could be a problem for others. So with these deficiencies, why still 4 stars? Because it's cheap, it meets my needs perfectly, and got here quick.
