In this blog, we’re going to introduce the more than 20 the most useful Arduino shields to help you extend more possibilities for your Arduino projects.
What is Arduino Shield?
The Arduino Shield usually has the same pin position as the Arduino development board and can be stacked and plugged into the Arduino to implement specific functions.
Although it is convenient to plug in the components on the breadboard, you are required to use some electronic knowledge to build various circuits. Using the expansion board can simplify the circuit construction process to a certain extent, and build your own project more quickly.
With the help of Arduino shields and senor expansion boards, you only need to connect various sensors and modules to the shield through the connection cable. For example, if you use the network expansion board, you can easily let the Arduino get the network communication function.
Arduino Shield is one of the most commonly used Arduino peripheral hardware. Let’s take a look at which shield we should get started with first 🙂
You can find a wide range of Arduino shields on our website. According to the function, it is divided into
Arduino Uno is the most popular Arduino board so far, however, it is sometimes frustrating when your project requires a lot of sensors or Leds and your jumper wires are in a mess. The purpose of creating the Grove – Base Shield is to help you get rid of breadboard and jump wires. With the rich grove connectors on the baseboard, you can add all the grove modules to the Arduino Uno very conveniently!

Camera Shield is the first shield board that support photograph, it is based on the solution of VC0706 + OV7725, the former is a high performance camera processor with enhanced image processing functions and it embedded the hard-wired JPEG codec, and the latter is a high-performance ¼ inch, single-chip VGA camera and image processor in a small footprint package. We have written our library to control the Camera Shield via UART/SPI, which makes it possible to take picture easily by your Arduino board. Come on and use it to take a photo!
The new version of XBee Shield is a standardized and stackable shield compatible with Arduino. You can easily stack any modules from the Bee series onto it, and build a wireless network for your project. In spite of that, it is also equipped with the function of level conversion, which enables a double-way conversion between high & low IO levels. The reserved digital pins facilitate users to select the TX/RX port using jumper caps.
The W5500 Ethernet Shield can be used to provide your projects with internet connectivity. W5500 enables users to have the Internet connectivity in their applications just by using the single chip in which TCP/IP stack, 10/100 Ethernet MAC and PHY embedded. The shield also has two Grove connectors and a microSD card socket to support projects which require storing large amounts of data from Grove sensor.
The shield covers a wide range and transmit strong signals with the newly, stable on-board antenna.
- Featured with RN171 TCP/IP module, the WiFi shield allows your Arduino/Seeeduino to connect wireless networks up to 802.11b/g.
- The RN171 module supports TCP, UDP, FTP and HTTP communication protocols, which meet the needs of most wireless and Internet of Things (IoT) network projects, such as smart home networks, robots controls and personal weather stations.
RS232 Shield is a standard communication port for industry equipment. This module is base on MAX232, which is a dual driver/receiver that includes a capacitive voltage generator to supply TIA/EIA-232-F voltage levels from a single 5-V supply. The shield integrates DB9 connectors (female) that provide a connection to various devices with RS232 interface. Also, the RS232 headers will facilitate your connections and commissioning. It provides the welding areas to make full use of extra space on it, which is highly convenient for prototyping.

It integrates a series of external interfaces,such as CAN, Ethernet, USB and 4 standard Grove sockets, all together on a single board.The Mbed Shield is also compatible with other standard Arduino Shields, providing you an even more powerful extension for your Mbed.
Arduino Display shield
This is a multifunctional Arduino/Seeeduino/Arduino Mega compatible resistive touch screen. It can be used as a display device or sketch pad. Compared with the previous version, 2.8’’TFT Touch Shield V1.0, we replaced the screen driver with a more professional chip, ILI9341 driver, providing different pin-saving SPI communication without sacrificing the data transmitting speed. Due to the communication method change, programs developed for the original version need modifications before being transplanted to the new version. With an SD card module integrated also on this shield, this shield reserves great room for other expansions to your project.
E-Ink screen also known as E-paper screen, we have released several E-Ink screens of various sizes, including grove E-Ink module, raspberry pi E-Ink hat.
The 2.7” Triple-Color E-Ink Display is an Arduino E-Ink display shield, which contains 264×176 pixels, and can display white/black/red for each pixel. This shield communicates with Arduino via the SPI interface and it reserves a Grove I2C interface for use with other modules. With the help of a comparison circuit, the module achieves self-adaption of the 3.3V and 5V voltage system.
Small e-paper shield is a driver shield for e-paper of small sizes. It’s capable of driving e-papers of 1.44 inch, 2.0 inch and 2.7 inch and supports more than 170 langusges. The upper surface of this shield is left flat and clean to give great support to the e-paper attached to it. If you are considering a lightweight and comfortable to read display, e-paper would be a good choice.
It is the smallest Arduino display module you can find so far.
You could connect it to Ardunio micro directly without doing any PCB layout and also available for other controllers.
Motor Shields for Arduino

It lets you drive two DC motors with your Arduino/Seeeduino board, controlling the speed and direction of each one independently. You can also measure the motor current absorption of each motor, among other features.
The onboard DC/DC converter supports a very wide range of input voltage and can provide a 5V power supply for the microcontroller board with 100mA maximum current. So, you just need one power supply to drive the motors and power up the logic circuit.
