In addition to all the features of the previous board, the Uno now uses an ATMega16U2 instead of the ATMega8U2 chip. This allows for faster transfer rates and more memory. No drivers needed for Linux or Mac (inf file for Windows is needed and included in the Arduino IDE), and the ability to have the Uno show up as a keyboard, mouse, joystick, etc.\u003c\/p\u003e \u003cp\u003e3.3VV\/5V Supply Voltage and IO Voltage is optional.\u003c\/p\u003e \u003cp\u003e\u003cbr\u003eMore 3.3V modules supported, such as Xbee module, Bluetooth module, RF module, GPRS module, GPS module, LCD5110 Backlight and so on, but the original version can only support 5V IO.\u003c\/p\u003e \u003cp\u003eController uses \u003cstrong\u003eSMD MEGA328P-AU chip\u003c\/strong\u003e.\u003c\/p\u003e \u003cp\u003eAdd A6\/A7 port.\u003c\/p\u003e \u003cp\u003eSainSmart R3 can directly use the electronic building blocks on I \/ O port and elicit G, V, S.\u003cbr\u003e\u003cbr\u003eThe Uno R3 also adds SDA and SCL pins next to the AREF. In addition, there are two new pins placed near the RESET pin. One is the IOREF that allow the shields to adapt to the voltage provided from the board. The other is a not connected and is reserved for future purposes. The Uno R3 works with all existing shields but can adapt to new shields which use these additional pins.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e   ATmega328-AU microcontroller\u003c\/li\u003e \u003cli\u003e    Input voltage - 7-12V\u003c\/li\u003e \u003cli\u003e    5V Electric current : 500MA\u003c\/li\u003e \u003cli\u003e    3.3V Electric current : 50MA\u003c\/li\u003e \u003cli\u003e    14 Digital I\/O Pins (6 PWM outputs)\u003c\/li\u003e \u003cli\u003e    8 Analog Inputs\u003c\/li\u003e \u003cli\u003e    32k Flash Memory\u003c\/li\u003e \u003cli\u003e    16Mhz Clock Speed\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eThe SainSmart LCD4884 Shield \u003c\/strong\u003eprovides 48x48 display. This LCD shield can apparently meet your needs to display much information. It can display English, Chinese, even images. It also integrates a 5 DOF joystick. The shield has 6 Digital IO and 5 Analog IO. This 3 pin connector has a temperature sensor which can help indicate the temperature.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eThe SainSmart Prototype Shield\u003c\/strong\u003e is a great kit to new  users and geeks who have sparkling ideas. You can choose to do soldering in the soldering area. You can also make good use of the mini breadboard which can save your time of soldering. Try any circuit you want to the Arduino. You also can choose to use your own breadboard.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eThe Ultrasonic Module HC-SR04 Distance Sensor\u003c\/strong\u003e are 4 pins : VCC , Trig, Echo, GND . So it's a very easy interface for controller to use it ranging. The all process is: pull the Trig pin to high level for more than 10us impulse, the module start ranging;finish ranging. If you find an object in front , Echo pin will be high level , and based on the different distance, it will take the different duration of high level. So we can calculated the distance easily :\u003cbr\u003eDistance = ((Duration of high level)*(Sonic :340m\/s))\/2\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003ePackage Content:\u003c\/strong\u003e\u003cbr\u003e\u003cem\u003e1 SainSmart Uno for Arduino\u003c\/em\u003e\u003cbr\u003e\u003cem\u003e1 SainSmart LCD4884 Shield\u003c\/em\u003e\u003cbr\u003e\u003cem\u003e1 SainSmart Prototype Shield (with Breadboard Jump Wires)\u003c\/em\u003e\u003cbr\u003e\u003cem\u003e1 SainSmart HC-SR04 Distance Sensor\u003c\/em\u003e\u003c\/p\u003e \u003cp\u003e\u003cspan style=\"color: #ff0000;\"\u003eDocument:\u003c\/span\u003e\u003c\/p\u003e \u003cp\u003e\u003ca href=\"https:\/\/s3-ap-northeast-1.amazonaws.com\/sain-amzn\/20\/20-011-906\/LCD4884s.rar\" target=\"_blank\" rel=\"noopener noreferrer\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003eDownload Link\u003c\/span\u003e\u003c\/a\u003e\u003c\/p\u003e","brand":"SainSmart","offers":[{"title":"Default Title","offer_id":49290309828762,"sku":"20-011-C77","price":25.9,"currency_code":"GBP","in_stock":true}],"url":"https:\/\/coretarps.co.uk\/products\/sainsmart-uno-r3-sainsmart-graphic-lcd4884-shield-sainsmart-prototype-shield-with-breadboard-jump-wires-hc-sr04-ultrasonic-distance-sensor","provider":"My Store","version":"1.0","type":"link"}
