{"product_id":"dfrduino-uno-r3","title":"DFRduino Uno R3","description":"\u003cp\u003eThe DFRduino Uno V3.0 from DFRobot is a compact physical world computing board for learning or development. It is a simple microcontroller board fully compatible with the Arduino UNO R3 and Arduino IDE open-source development environment. This environment implements the Processing \/ 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).\u003cbr\u003e\u003cbr\u003eThis board features the ATmega16U2 programmed as a USB-to-serial converter. An added bonus is that our DFRduino is still using the DIP package AVR Chip. You could remove it to update or reprogram the chip's firmware, or even place it on a finished, more compact project. The cool thing about our new DFRduino microcontroller is that the headers use different colours to feature I\/O ports of different types:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eRed for Power Section\u003c\/li\u003e\n\u003cli\u003eBlue for Analog I\/O\u003c\/li\u003e\n\u003cli\u003eGreen for Digital I\/O\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThese colours match our sensor cables. This makes it really easy to figure out where to connect sensors or to identify which side is Analog (blue) or Digital (green).\u003cbr\u003e\u003cbr\u003eThe 'Arduino Uno' is a microcontroller board based on the ATmega328. It has 14 digital input\/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a robust printer-style USB cable or power it with an AC-to-DC adapter or battery to get started.\u003cbr\u003e\u003cbr\u003eThis board added SDA and SCL pins that are near the AREF pin and two other new pins placed near the RESET pin, the IOREF that allow the shields to adapt to the voltage provided by the board. In future, shields will be compatible both with the board that use the AVR, which operate with 5V and with the 'Arduino Due' which operate with 3.3V. The second one is a not connected pin, that is reserved for future purposes.\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMicrocontroller: ATmega328 (DIP Package)\u003c\/li\u003e\n\u003cli\u003eOperating Voltage: 5V\u003c\/li\u003e\n\u003cli\u003eInput Voltage (recommended): 7 ~ 12V\u003c\/li\u003e\n\u003cli\u003eInput Voltage (limits): 6 ~ 20V\u003c\/li\u003e\n\u003cli\u003eDigital I\/O Pins: 14 (of which 6 provide PWM output)\u003c\/li\u003e\n\u003cli\u003eAnalog Input Pins: 6\u003c\/li\u003e\n\u003cli\u003eDC Current per I\/O Pin: 40 mA\u003c\/li\u003e\n\u003cli\u003eDC Current for 3.3V Pin: 50 mA\u003c\/li\u003e\n\u003cli\u003eFlash Memory: 32 KB of which 2KB is used by bootloader\u003c\/li\u003e\n\u003cli\u003eSRAM: 2 KB (ATmega328)\u003c\/li\u003e\n\u003cli\u003eEEPROM: 1 KB (ATmega328)\u003c\/li\u003e\n\u003cli\u003eClock Speed: 16 MHz\u003c\/li\u003e\n\u003cli\u003eSize: 75 x54 x15 mm\u003c\/li\u003e\n\u003cli\u003eEnvironment Friendly: Rohs Compliance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eATmega328P datasheet\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePackage Contents\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1x DFRduino Uno \u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DFRobot","offers":[{"title":"Default Title","offer_id":48623711551706,"sku":"cdz1789676578113","price":10.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0824\/8318\/3834\/files\/dfrduino-uno-r3_1.jpg?v=1789676586","url":"https:\/\/memoryfoamwear.shop\/products\/dfrduino-uno-r3","provider":"My Store","version":"1.0","type":"link"}
