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.
"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.
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...
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.
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 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.
This is Version 2.0 of the Xboard. The main improvement is that it now operates at 5V, making it compatible with most sensors and I2C protocol with out the need of a voltage level converter. The XBoard is a unique Arduino board which features a WIZnet ethernet port, an XBee socket, and an ATMega328. This board will add wireless XBee control as well as internet connectivity to your projects. Its great for anything from home automation to robot control. The possibilities are endless!
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.
The Dreamer Nano V4.0 is a surface mount breadboard embedded version of the ATMEGA 32U4 with integrated Micro USB. It has everything that Arduino Leonardo has (electrically).Physically, it is just missing power jack to save space.
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...
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.
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.
