Example: The large power connector on an Arduino, though not needed for most uses that I've had, does get in the way of that part of the protoboard right above it. You will notice things with placement that didn't popup earlier. Eagle is great for a preliminary overview, but physically seeing it in reality helps even further. Use the Eagle PCB design program to interactively place different parts on the board, and see if they will fit where you think they should go.ģ) Do several dry runs of placing parts. Headers just get in the way - so put them on dead last.Ģ) Download the Eagle design files first instead. That's because often when one is mounting parts, you need to be able to come in from various sides to put soldering iron to solder, wire, and part. As a matter of fact, soldering the headers on is the absolute last thing you want to do. Let me outline my suggestions:ġ) Don't put it together when you first get it. Otherwise, you are likely to make mistakes. That was time well spent, and I would recommend others do the same. Since I have to be quite careful with the very limited funds that I can spend on my 'toys', I spent a couple of months planning out how to use this kit before I even got it. It's extremely flexible, as I discovered when I was outlining how to use it. First of all, let me state that it's obvious to me that a lot of thought went into designing this product. The SparkFun ProtoShield Kit does not come pre-assembled. Note: Since this product is a kit, assembly and a basic knowledge of soldering will be required. On this test area you will find soldering areas for the two yellow 3mm LEDs (as well as pins to control and power them), two 330 Ohm resistors, a 10K Ohm resistor, and a pushbutton. We have also moved the prototype testing components (those used to make sure your circuit works effectively) off of the "mainland" of the shield and onto a ProtoSnap styled, removable PCB. For those that prefer the standard prototyping pads, we left the other side (near the BlueSMiRF and Serial UART ports) as is. Once you add a component, simply add a solder jumper between holes to make a connection. On the underside of the shield you will be able to see open jumper pads between each through hole to make a connection like a breadboard. One of our favorite features with this version of the ProtoShield Kit is the solderable-like breadboard prototyping area! Half of this area was designed with a breadboard in mind. While you can probably do the same with breakout boards, shields will allow you to do it easier and more efficiently.The SparkFun ProtoShield Kit lets you customize your own Arduino shield using whatever circuit you can come up with and then test it to make sure everything is working the way it should! The SparkFun ProtoShield Kit is based off the Arduino R3’s footprint that allows you to easily incorporate it with favorite Arduino-based device. Since they stay in place, they are more appropriate for finished projects, especially if you plan on moving them often.Īnother benefit of Arduino shields is that they are built for more complex functions, like GPS and cellular communication systems. They require much less wiring and have fixed functionality for their connections. Shields are essentially building blocks for your projects. In comparison, a breakout board can easily be moved. A shield won’t budge much once it’s connected. There’s a reason for that, and it’s because of the connectivity. An Arduino shield will be roughly the same size as the Arduino, while a breakout board is usually smaller. The first thing you’ll undoubtedly notice is the size. While they might do similar things, there are significant differences between them. If you already know something about breakout boards , you might wonder why there are both shields and breakout boards. It is taller than headers and thus blocks another shield from fitting properly. In other words, it can stack onto others, but won’t allow others to stack onto it.īig and bulky components are also a dead giveaway that the shield doesn’t allow stacking. If there are none, or they don’t seem aligned correctly, that shield likely doesn’t allow stacking. Keep in mind that not all shields are stackable. This allows you to add even more functionality to your Arduino. If everything is inserted correctly, the shield won’t budge when moved.Īs mentioned before, shields can attach or stack on one another. When attaching a shield to an Arduino board, you will plug shield pins into Arduino’s headers. You plug components and wires in them.Īrduino shields will have long pointy metal pieces on the bottom called pins. When looking at the sides of an Arduino board, you will see two black plastic rows with holes on top.
