![]() ![]() The cable is available as a USB Type A/B or USB Type B/C or Type B/C Right. A USB cable is available separately should you require it. The Arduino Uno R3 features a USB Type B connector for programming, power, and application monitoring for connection to a host computer. The genuine Arduino Uno and this model incorporate an ATmega16U2 processor for onboard communications eliminating the need for intermediate drivers or patches. Other boards utilize an intermediate onboard driver (such as a CP2102) to interface the Arduino UNO to the USB port, which requires a unique extra driver. Unlike other boards that require a particular driver, the Arduino IDE immediately recognizes this board without the need for additional drivers. Our Arduino Uno R3 is fully compatible with the genuine Arduino Uno. The Arduino Uno R3 is completely compatible with the genuine UNO R3 and no special drivers are required. Power External: Through 2.1mm barrel jack (7v to 12v DC)ĭigital I/O Pins: 14 (of which 6 provide PWM output)Ĭlock Speed: 16 Mhz Setup and Configuration Power 5V: Provided through USB Type-B Port See our complete line of Arduino-compatible devices. The other unit (see UNO R3 with CH340) has the same functionality but uses a CH340 UART for the USB interface and is less expensive. ![]() ![]() One is a replica of the original UNO R3 (see UNO R3 with ATmega16U2), which does not require any extra drivers. We offer two versions of the Arduino UNO R3 compatible devices. ![]() The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet). Due to the low cost, you can tinker with your Uno without worrying too much about doing something wrong. Arduino Uno R3 Compatible ATMega328P+ATMega16U2. It contains everything needed to support the microcontroller simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started. It features 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header, and a reset button. The recommended range is 5v to 12v for Arduino Uno.Arduino UNO R3 Fully Arduino Uno R3 CompatibleĪrduino Uno R3 is a microcontroller board based on the ATmega328P. If using more than 12V, the voltage regulator may overheat and damage the board. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may be unstable. The board can operate on an external supply of 6 to 20 volts. Also leads from a battery can be inserted in the GND and VIN pin headers of the Power connector. The adapter can be connected by plugging a 2.1mm center-positive plug into the board’s power jack. While the Arduino UNO can be powered via the USB connection or with an external power supply, the power source is selected automatically.Įxternal (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. Instead, it features the Atmega16U2Atmega8U2 up to version R2) programmed as a USB-to-serial converter. The Uno differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Using the board is also very easy, simply connect it to a computer with a USB cable or power it with DC adapter or battery to get started. It contains everything needed to support the microcontroller. This Board has 14 digital input/output pins, 6 analog input pins, Onboard 16 MHz ceramic resonator, Port for USB connection, Onboard DC power jack, An ICSP header and a microcontroller reset button. The Arduino Uno R3 is a open source microcontroller board based on the ATmega328 chip. ![]()
