If this is your first experience with electronics and coding, the UNO is the most robust board you can start playing with. The UNO R3 is the most used and documented board of the whole Arduino family. The UNO R3 is a microcontroller board based on the ATmega328P. It has 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. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.<br>Differences with other boards<br>- The UNO R3 differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Instead, it features the Atmega16U2 (Atmega8U2 up to version R2) programmed as a USB-to-serial converter.<br>Revisions<br>- 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. In future, shields will be compatible with both the board that uses the AVR, which operates with 5V and with the Arduino Due that operates with 3.3V. The second one is a not connected pin, that is reserved for future purposes.<br>- Stronger RESET circuit.<br>- Atmega 16U2 replace the 8U2. Means a higher transfer rate and memory.<br>Communication<br>- The Uno has a number of facilities for communicating with a computer, another Uno board, or other microcontrollers. The ATmega328 provides UART TTL (5V) serial communication, which is available on digital pins 0 (RX) and 1 (TX). An ATmega16U2 on the board channels this serial communication over USB and appears as a virtual com port to software on the computer. The 16U2 firmware uses the standard USB COM drivers, and no external driver is needed. However, on Windows, a .inf file is required. The Arduino Software (IDE) includes a serial monitor which allows simple textual data to be sent to and from the board. The RX and TX LEDs on the board will flash when data is being transmitted via the USB-to-serial chip and USB connection to the computer (but not for serial communication on pins 0 and 1).<br>Memory<br>- The ATmega328 has 32 KB (with 0.5 KB occupied by the bootloader). It also has 2 KB of SRAM and 1 KB of EEPROM<br>.<br>Technical specs<br>- Model: UNO R3 (Revision 3)<br>- Microcontroller: ATmega328<br>- Atmega16U2 (NOT CH340) for USB/Serial Interface; No extra driver needed<br>- Operating Voltage: 5V<br>- Input Voltage (recommended): 7-12V<br>- Digital I/O Pins: 14 (of which 6 provide PWM output)<br>- Analog Input Pins: 6<br>- DC Current per I/O Pin: 40 mA<br>- DC Current for 3.3V Pin: 50 mA<br>- Flash Memory: 32 KB (ATmega328) of which 0.5 KB used by bootloader<br>- SRAM: 2 KB (ATmega328)<br>- Digital I/O Pins: 14 (of which 6 provide PWM output)<br>- EEPROM: 1 KB (ATmega328)<br>Hardware Specification<br>- Included USb cable length: 51.5cm<br>- Board Color: Blue<br>- Net weight:51g<br>- Gross contents weight: 61g<br>Included in this package<br>- 1 x ATmega328P Atmega16U2 Board<br>- 1 x USB Cable<br>- 4 x Pin Headers<br>Shipping & Payment<br>Payment<br>-<br>We require<br>Paypal<br>payment only.<br>- Your order will be cancelled if the payment is not received in one week.<br>We offer USPS First Class Shipping /<br>Not Ecomomy<br>- There is a big difference between USPS First Class Shipping and Economy Shipping<br>- Ecomomic delivery could take upto 5 days even to reach the seller's local post office<br>- Economy are collected in bulk by a third courier and shipped to post office to receive a discount<br>- Our orders are shipped daily and sent to USPS post office directly<br>- Please place an order with us.
