The Ethernet Shield for Arduino is based on the Wiznet W5100 and connects your Arduino-compatible board to the internet a few minutes. Simply plug this module onto board, connect it to your network with an RJ45 cable (not included) and follow a few simple instructions to start controlling your world through the internet.
The DFRobot Single Relay blocks the number of electronic modules. It can be used in interactive projects. It can also be used to control the lighting, electrical and other equipments. The modular design makes it easy to expand with the Arduino board (not included). The Relay output state by a light-emitting diode. It can be controlled through the digital IO port, such as solenoid valves, lamps, motors and other high current or high voltage devices.
A relay is an electrically operated switch, which has a control system (also known as the input circuit) and the controlled system (also known as the output circuit), usually used in automatic control circuit.It is actually "automatic switch" ,using a small electric current to control a larger current.
This is 8 digital bits serial LED display. It features a flick free display and 3-Wire interface which allows more than 2 modules can be serial linked. With our interface shield, this module can be plug and play.
This is an I2C DAC module that outputs 0-25mA current. It offers more accurate 4-20mA current output after calibration, which can be used with most 4-20mA...

We've done all the hard work; leaving the final steps for you to set up your OctoPrint Server and print remotely from your 3D printer! All you have to do is insert it into your Raspberry Pi with your printer and follow this tutorial.
DFRobot I2C ADS1115 16-bit ADC module can accurately collect and convert analog signals. Through this ADC module, Raspberry Pi can easily use a wide range of Gravity...
The DFRduino Ethernet Shield V2 is finally released. This new version supports Mega both 1280 and 2560. And it supports Micro SD card read/write as well. The ethernet shield is fully functional now. The V2 Ethernet Shield is fully compatible with Arduino Ethernet Shield. With the offical ethernet library, you can do exactly the same thing as the original one. But at a more affordable price.
"Greenhouse Effect" is melting the Earth ice core every minute and creating dangerous icebergs. By knowing the exact concentration of CO2, we can do somehing to reduce the CO2 and to protect our Earth. For that reason, this CO2 sensor is designed by DFRobot engineer. This is the first CO2 sensor in Arduino market. The output voltage of the module falls as the concentration of the CO2 increases. The potentiometer onboard is designed to set the threshold of voltage. As long as the CO2 concentration is high enough (voltage is lower than threshold), a digital signal (ON/OFF) will be released.
Most project of Arduino may need more than two voltage supply. When feed with from 4.5-35V, this power shield able to provide a voltage range from 1.25-12V with 3A peak current.
Stop fiddling with micro SD card sockets in the back of your latest gadget during development, and give yourself a little more elbow room with this Small Micro SD...
The DFRduino Nano USB Microcontroller V3.1 (ATMega 328) is a breadboard ready version of the Arduino mini with integrated USB. The Nano has everything that the Diecimila has (electronically) with more analog input pins and an on-board +5V AREF jumper. The Nano automatically senses and switches to the higher power supply, so there is no need for a power select jumper.
DFRduino Mega1280 is a microcontroller board based on the ATmega1280. It has 54 digital input/output pins, 16 analog inputs, 4 UARTs (hardware serial ports), a 16...
Combines the power of screw shield and prototyping shield. This Proto Screw shield offers a better way to do prototyping. The Screw terminal can be screwed directly to the terminal on the thread and is reliable and convenient. It can be plugged into the Arduino controller. You can use this shield to save yourself from the bad port connection. Feel secure with this arduino-compatible screw shield.
This is a digital tilt switch. It can be used as a simple tilt sensor. Simple plug to our IO/Sensor Expansion board, you can make amazing interactive projects.
FireBeetle ESP32-E, specially designed for IoT, is an ESP-WROOM-32E-based main controller board with dual-core chips. It supports WiFi and Bluetooth dual-mode communication...
This is a basic breakout board for the FTDI FT232RL USB to serial IC. The pinout of this board matches the FTDI cable to work with official Arduino and cloned 3.3V Arduino boards. It can also be used for general serial applications. The major difference with this board is that it brings out the DTR pin as opposed to the RTS pin of the FTDI cable. The DTR pin allows an Arduino target to auto-reset when a new Sketch is downloaded.
This is a new version of the FTDI breakout board features an Atmega8U2 programmed as a USB-to-serial converter, the same chip found on the Arduino Uno.
