Arduino UNO R3 CH340G ATMega328P + cable

Arduino Uno is one of the most popular development platforms. Although it is the most widely used among Arduino motherboards, this product is the clone version. 

There are two different versions of the product. In this version, the CH340 IC is used. Another feature is the atmega328 microcontroller with the arduino bootloader installed on this card as SMD. In other clone options, it is possible to remove the microcontroller from the card. However, since this situation increases the cost of the product, the price increases.

Arduino is the most affordable and easy to use model for beginners.

Arduino Uno – R3 SMD model, unlike the original Arduino models, comes with a USB cable as a gift.

R3 is also referred to as REV3. It is the 3rd revision and the most recent revision of the card.

Although there is no difference in working principle, it may require installing a driver for the CH340 IC in order to connect it to your computer on devices under Windows7. Since it is a clone product, it is very advantageous in price.

Arduino Nano is a small motherboard based on the ATmega328P. It has about the same features as the Arduino Duemilanove, only it lacks a DC power jack. Arduino IDE application is needed 
for programming . The Arduino Nano is powered by the Mini-B USB connection. The power supply automatically selects the high voltage source. The operating voltage is in the range of 5V - 12V. However, the recommended operating voltage should be more than 7V. 9V batteries will be sufficient for operation. 

In this clone version of Arduino Nano board, CH340 IC is used instead of Standard FTDI or 16U2 chips. 
Thus, the cost was reduced, but there was no change in performance.  

Features:

• Micro-Controller: ATmega328P
• Operating Voltage: 5V
• Input Voltage (recommended): 7-12V
• Digital I/O Pins: 14 (6 of them to provide PWM output)
• Analog Input Pins: 8
• Flash Memory : 32 KB
• Operating Frequency: 16 MHz
• Dimensions : 19x43mm

Package Included:

• 1 x Arduino Nano Clone CH340
• 1 x USB C Cable
