Tech specs
The Arduino Ethernet Shield 2 allows an Arduino Board to connect to the internet. It is based on the (Wiznet W5500 Ethernet chip). The Wiznet W5500 provides a network (IP) stack capable of both TCP and UDP. It supports up to eight simultaneous socket connections. Use the Ethernet library to write sketches that connect to the Internet using the Shield. The Ethernet Shield 2 connects to an Arduino Board using long wire-wrap headers extending through the Shield. This keeps the pin layout intact and allows another Shield to be stacked on top of it.
The most recent revision of the board exposes the 1.0 pinout on rev 3 of the Arduino UNO Board.
The Ethernet Shield 2 has a standard RJ-45 connection, with an integrated line transformer and Power over Ethernet enabled.
There is an onboard micro-SD card slot, which can be used to store files for serving over the network. It is compatible with the Arduino Uno and Mega (using the Ethernet library). The onboard micro-SD card reader is accessible through the SD Library. When working with this library, SS is on Pin 4. The original revision of the Shield contained a full-size SD card slot; this is not supported.
The Shield also includes a reset controller, to ensure that the W5500 Ethernet module is properly reset on power-up. Previous revisions of the Shield were not compatible with the Mega and needed to be manually reset after power-up. The current Shield supports a Power over Ethernet (PoE) module designed to extract power from a conventional twisted pair Category 5 Ethernet cable.
PoE module features as follows:
- IEEE802.3af compliant
- Input voltage range 36V to 57V
- Overload and short-circuit protection
- 12V Output
- High efficiency DC/DC converter: typ 85% @ 80% load
- 1500V isolation (input to output)
NB: the Power over Ethernet module is proprietary hardware not made by Arduino, it is a third party accessory. For more information, see the datasheet
The Shield does not come with a built in PoE module, it is a separate component that must be added on. Arduino communicates with both the W5500 and SD card using the SPI bus (through the ICSP header). This is on digital pins 10, 11, 12, and 13 on the Uno and pins 50, 51, and 52 on the Mega. On both boards, pin 10 is used to select the W5500 and pin 4 for the SD card. These pins cannot be used for general I/O. On the Mega, the hardware SS pin, 53, is not used to select either the W5500 or the SD card, but it must be kept as an output or the SPI interface won't work.
Note that because the W5500 and SD card share the SPI bus, only one at a time can be active. If you are using both peripherals in your program, this should be taken care of by the corresponding libraries. If you're not using one of the peripherals in your program, however, you'll need to explicitly deselect it. To do this with the SD card, set pin 4 as an output and write a high to it. For the W5500, set digital pin 10 as a high output.
- The Shield provides a standard RJ45 Ethernet jack.
- The reset button on the Shield resets both the W5500 and the Arduino Board.
- The Shield contains a number of information LEDs:
- ON: indicates that the Board and Shield are powered
- 13 is the Arduino standard built in LED
- ACT: flashes when RX or TX activity is present
- LINK: indicates the presence of a network link and flashes when the Shield transmits or receives data
In this picture below we have tagged the yellow ACT, the green LINK,, the 13 Built in LED and the ON LED.
This shield also hosts Tinkerkit compatible connectors as follows:
- 2 TinkerKit connectors for two Analog Inputs (in white), connected to A2 and A3.
- 2 TinkerKit connectors for two Aanlog Outputs (in orange in the middle), connected to PWM outputs on pins D5 and D6.
- 2 TinkerKit connectors for the TWI interface (in white with 4 pins), one for input and the other one for output.

I'm excited to share the details of my BT Arduino Tank project, which incorporates some impressive 3D-printed components. While the main chassis of the tank was not 3D-printed, I utilized this technology to create two crucial parts: the enclosure for the motor driver and the compartment housing the remaining electronics. Additionally, I 3D-printed a cannon for an added touch of customization. The enclosure for the motor driver served as a protective housing, ensuring that the L298N motor driver module was securely mounted and shielded from external elements. By designing and 3D-printing this part, I could precisely fit it to the tank's specifications, providing a neat and organized arrangement of the electronics. In the same vein, the compartment for the remaining electronics, such as the Arduino Nano Every and the HC-05 Bluetooth module, was also 3D-printed. This enclosure offered a clean and organized solution for housing these components, safeguarding them while maintaining easy access for maintenance or modifications. Lastly, to enhance the tank's appearance and add a touch of personalization, I designed and 3D-printed a cannon. This custom-printed cannon perfectly complemented the overall design, making the tank even more visually appealing. By strategically incorporating 3D printing into specific parts of the project, I achieved a balance between functionality and customization. The precision and versatility of 3D printing allowed me to create tailored enclosures and a unique cannon, elevating the overall aesthetic and practicality of my BT Arduino Tank project.
KITT (Knight Industries Two Thousand) was a fictional car based on a 1982 Pontiac Trans Am in the Knight Rider television series. KITT featured an artificial intelligence, voiced by the legendary William Daniels, and some iconic styling. Savall21 built a replica RC KITT and used Arduino boards to add sound and light effects that he can trigger with the RC transmitter. This is a custom RC car created by Savall21 using a Tamiya TT-02 kit and a resin 3D-printed body shell. The controller/transmitter is a Jumper T18, which has a customizable touchscreen interface. Savall21 programmed his own widget for that touchscreen. It mimics the fictional KITT control panel and lets the user select different sound effects and activate the iconic headlights. The T18 sends commands to an FrSky XR8 radio receiver located in the car. The FrSky receiver communicates with two Arduino Nano Every boards via the S.Port. The first Arduino controls the sound effects, which play through a DFPlayer Mini MP3 player module. The FrSky receiver simply sends a numerical code to the Arduino, which then activates the corresponding audio clip. The second Arduino drives a strip of WS2812B individually addressable RGB LEDs for the headlights and taillights. The user can control the headlights directly, while the taillights automatically come on any time the throttle is below 50%. For fans of Knight Rider and RC vehicles, this is the ultimate project. The car looks fantastic and the Arduino effects add polish to the build.
