Arduino UNO SMD Rev3 also known as Arduino UNO R3 SMD Edition Atmega328p CH340 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 ceramic resonator (CSTCE16M0V53-R0), a USB connection, a power jack, an ICSP header, and a reset button.

Arduino Uno R3 smd ch340 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 start it.

The Arduino UNO SMD Rev3 differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. Its surface-mounted (SMD) processor makes this Arduino Uno Rev3 more resistant to external aggressions, including vibration.

Arduino Uno R3 SMD atmega328p development board based on the ATmega328 microcontroller. The ATmega328 is a low power CMOS 8bit microcontroller based on the AVR enhanced RISC architecture.

By executing powerful instructions in a single clock cycle, the ATmega328 achieves throughputs approaching 1MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.

Arduino Uno R3 smd CH340 evaluation board has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16MHz 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 USB cable or power it with a AC to DC adapter or battery to start it.

The arduino uno R3 smd atmega328 is an open-source microcontroller board based on the Microchip Atmega328P microcontroller and developed by Arduino.cc.

This programmable Uno R3, has most of the features of the Uno with the added benefit of an ISP header and CH340G interface.

Arduino UNO SMD Rev3 Features: –

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.
Stronger RESET circuit.
Atmega 16U2 replace the 8U2.

Arduino UNO SMD Rev3 Power: –

The Arduino Uno board can be powered via the USB connection or with an external power supply. The power source is selected automatically.

External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The adapter can be connected by plugging a 2.1mm center-positive plug into the board’s power jack. Leads from a battery can be inserted in the GND and Vin pin headers of the POWER connector.

The board can operate on an external supply from 6 to 20 volts. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may become unstable. If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range is 7 to 12 volts.

ARDUINO UNO R3 SMD Edition Memory: –

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 (which can be read and written with the EEPROM library).

ARDUINO UNO R3 SMD Edition Programming : –

The Arduino Uno can be programmed with the (Arduino Software (IDE)). Select “Arduino/Genuino Uno from the Tools > Board menu (according to the microcontroller on your board). For details, see the reference and tutorials.

The ATmega328 on the Arduino Uno comes preprogrammed with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. It communicates using the original STK500 protocol (reference, C header files).

You can also bypass the bootloader and program the microcontroller through the ICSP (In-Circuit Serial Programming) header using Arduino ISP or similar; see these instructions for details.

The ATmega16U2 (or 8U2 in the rev1 and rev2 boards) firmware source code is available in the Arduino repository. The ATmega16U2/8U2 is loaded with a DFU bootloader, which can be activated by:

On Rev1 boards: connecting the solder jumper on the back of the board (near the map of Italy) and then rese ing the 8U2.
On Rev2 or later boards: there is a resistor that pulling the 8U2/16U2 HWB line to ground, making it easier to put into DFU mode.

You can then use Atmel’s FLIP software (Windows) or the DFU programmer (Mac OS X and Linux) to load a new firmware. Or you can use the ISP header with an external programmer (overwriting the DFU bootloader). See this user-contributed tutorial for more information.
