There are hundreds of Arduino shields on the market these days, and going through each will turn this article into a lecture. Take a look at Adafruit for some good examples. Some shields include an array of plated holes for soldering through-hole components, while others are designed for a very particular application and are not expandable. If you’re buying a premade shield, you’ll find that not all of these modules are extensible.

Shields generally communicate using SPI, I 2 C, or serial communication, and some use interrupts or analog inputs. Some Arduino shields are designed to use every pin, while some shields leave open pins. Typical shield form factor for an Arduino Uno An example footprint for an Arduino Uno shield is shown below. Power and ground pins are located on one eight pin header, the analog pins are placed on a six-pin header, and the digital pins are placed on the opposite side with an eight-pin and ten-pin header. Note that this is not generally the case with a custom shield, which is normally fabricated for a specific set of functions.Īrduino shields have the same form factor as that of a standard Arduino board. If you use a through-hole shield, you can add more components to the board or rework it as needed. For a small manufacturing batch, you’ll find that they are cheaper compared to custom PCB. Shields are relatively inexpensive to buy or design.
Signals are sent from the GPIO pins or other MCU interface, and multiple shields can be stacked together to form a complex system. The layout of a shield board will be compatible with a basic Arduino board, which means they can be plugged in straight away. Arduino shields provide some important advantages: There are a number of capabilities you can add to an existing Arduino, such as Wi-Fi, Bluetooth, motor control, a camera, or other features. What is Arduino Shield Design?Īrduino shields are small circuit boards that sit on top of existing Arduino boards and contain additional components to boost the capabilities of the system.
#Arduino shields how to
Here’s what you need to consider in Arduino shield design and how to create a custom shield for your new product. If you’re more adventurous, you can create your own shield board that plugs directly into an Arduino module. If you are lucky, you might be able to find an existing shield that will hold your additional components. The other option is to take all the additional components and make an Arduino shield. You’ll also have to replicate Arduino’s functionality in your custom board, or you’ll have to clone an Arduino board.Īrduino shield design with expandable memory and an LCD display First, you could make a custom board that might be more organized, but will require some time to design.
Congratulations! If only a couple of ICs and additional circuitry could be added to your Arduino to make it look like a finished product. You probably have a great idea that you tested using your Arduino, breadboard, and what looks like a bird’s nest of connectors, and it works great.
