Output voltage: DC 5V / 3.3V ATmega328P No USB cable version This version can not compatible with OS system Features: Open the original schematic design, free development software interface download, also allow your needs to be modified, easy and convenient to download the program. Can simply use sensors, all kinds of electronic components connection (such as LED lights, buzzer, buttons and photosensitive resistance, etc.), make all sorts of interesting work. Using high-speed microprocessor controller (ATMEGA328), development interface and environment are all very simple, easy to understand, very suitable for beginners to learn. Description: Digital I / O: 0 - 13 Analog I / O: 0 - 5 Support ISP download function Input voltage: DC 5V ~ 9V (No external power supply when connected to the computer) Output voltage: DC 5V / 3.3V Using Atmel Atmega328 microprocessor controller How to use: 1. Download the IDE arduino Link: http: http://arduino.cc/en/Main/Software (Copy to open) 2. Download the USB chip driver Link: http://www.5v.ru/zip/ch341ser.zip (Copy to open) 3. Plug in UNO development board, the driver will be installed automatically 4. Select the UNO from the die 5. Select the COM port 6. The best choice first, arduino come with routine procedures, burn into it. Package included: 5 x UNO R3 Development Board

Output Voltage: DC5V / 3.3V / USB Atmega328P ATmega16U2 With USB cable version Description: UNO R3 board is 100% compatible with original Arduino, now it has perfect quality and performance. Arduino is an open-source physical computing platform based on a simple i/o board and a development environment that implements theProcessing/Wiring language. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g. Flash, Processing, MaxMSP). The open-source IDE can be downloaded for free (currently for Mac OS X, Windows, and Linux). This is the new Tosduino Uno R3. In addition to all the features of the previous board, the Uno R3 now uses an ATmega16U2 instead of the ATmega8U2 chip. This allows for faster transfer rates, no drivers needed for Linux or Mac (inf file for Windows is needed), and the ability to have the Uno show up as a keyboard, mouse, joystick, etc. Note: The TOSduino Uno R3 requires the Arduino 1.0 drivers folder in order to install properly on some computers. We have tested and confirmed that the R3 can be programmed in older versions of the IDE. However, the first time using the R3 on a new computer, you will need to have Arduino 1.0 installed on that machine. The small chip is ATmega16U2, the 28 pin DIP socket chip is ATmega328-pu. Performance description: Digital I / O digital input / output terminal: 0 to 13. Analog I / O Analog inputs / outputs: 0 to 5. Support ISP download function. Input voltage: No external power supply when connected to the computer USB, external power supply 5V ~ 9V DC voltage input. Output voltage: 5V / 3.3V DC. Using Atmel Atmega328 microprocessor controller. Package included: 5 x UNO R3 5 x USB cable

Description: Working Voltage: 5V(DC) Static Current: Less than 2mA. Output Signal: Electric frequency signal, high level 5V, low level 0V. Sensor Angle: Not more than 15 degrees. Detection Distance: 2cm-450cm. High Precision: Up to 0.3cm Input Trigger Signal: 10us TTL impulse Echo Signal: output TTL PWL signal Mode of connection: VCC trig(T) echo(R) GND Use method: Supply module with 5V, the output will be 5V while obstacle in range, or 0V if not.The out pin of this module is used as a switching output when anti-theft module, and without the feet when ranging modules. Note: the module should be inserted in the circuit before been power, which avoid producing high level of misoperation;if not, then power again. Module Working Principle: 1. Adopt IO trigger through supplying at least 10us sequence of high level signal. 2. The module automatically send eight 40khz square wave and automatically detect whether receive the returning pulse signal. 3. If there is signals returning, through outputting high level and the time of high level continuing is the time of that from the ultrasonic transmitting to receiving. Test distance =(high level time * sound velocity (340M/S) / 2. Note: This module is not suitable to connect with electric power, if you need to connect this module with electronic power,then let the GND terminal of this module to be connected first,otherwise, it will affect the normal work of the module Package Included: 5 x HC-SR04 Ultrasonic Module Distance Measuring Transducer
