1/19/2024 0 Comments Features of arduino uno r3It's intended for DIY, artists, designers, hobbyists, and anyone interested in creating interactive projects. Consult the manufacturer’s documentation or contact your reseller for more information.Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. They may use USB-to-serial chips that require additional drivers. Most Arduino-compatible “UNO” boards available today are based on the Arduino UNO R3 and can be used with the main Arduino Uno (Arduino AVR Boards) core. There exists a variety of clone and derivative boards, as well as other products marketed as “Arduino-compatible”, with “UNO” in the name. This limited edition UNO board comes in a smaller form factor, and has a USB-C connector.Īrduino-compatible “UNO” boards by other manufacturers Store page: Arduino UNO Mini Limited Edition Not to be confused with the Arduino UNO WiFi Rev2.īoard core: Arduino Uno Mini (Arduino AVR Boards) The u-blox NINA-W102 enables Bluetooth® and Wi-Fi connectivity.īoard core: Arduino Uno WiFi (Arduino AVR Boards)Ī version of the UNO R3 with an ESP8266 Wi-Fi module. The only UNO board that comes with an ATmega4809 microprocessor instead of an ATmega328P. When selecting your board in Arduino IDE it’s important to differentiate between Arduino Uno Wifi (Arduino AVR Boards) and Arduino Uno Wifi Rev2 (Arduino megaAVR Boards), and select the correct one for your board. Noticeably, the UNO WiFi Rev2 features an ATmega4809 microprocessor instead of the ATmega328P microprocessor used on the original UNO WiFi and all other UNO boards. It is sometimes refered to as the “R1” or “Rev1” version to distinguish it from later versions.īoard core: Arduino Uno Wifi Rev2 (Arduino megaAVR Boards) This revision added a resistor pulling the ATmega8U2 HWB line to ground, making it easier to set to DFU mode. This means it cannot easily be replaced like on the standard UNO R3.ĭocumentation: Arduino UNO Rev3 with Long PinsĪ version of the UNO R3 with longer pins on the bottom. On the SMD (Surface Mounted Device) version of the UNO R3, the ATmega328 microprocessor is soldered directly on the board. See also: Overview of the Arduino UNO Components The ATmega8U2 USB-to-serial chip was replaced with ATmega16U2.1.0 pinout: Added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board.Revision 3 of the board has the following new features: Today, the Arduino UNO R3 is the main successor to this line of boards, and the most popular official Arduino UNO board.īoard core: Arduino Uno (Arduino AVR Boards) Uses the Arduino Uno board core from the Arduino AVR Boards package.While “Arduino UNO” was also the name of the first Arduino UNO board model, it is now more often used to refer to any board with these characteristics: They use a different board package (Arduino UNO R4 Boards).īoard core: Arduino Uno R4 WiFi (Arduino UNO R4 Boards)īoard core: Arduino Uno R4 Minima (Arduino UNO R4 Boards).Unlike previous UNO boards, they do not use 8-bit AVR processors.The new Arduino UNO R4 Boards use a Renesas RA4M1 32-bit Arm® Cortex®-M4 processor.
