DescriptionArduino UNO SMD R3Arduino Uno R3 is the clone one of the latest version of Arduino Uno with an on-board CH340 usb – serial converter chip. Even there are some little differences with respect to the original one, it is almost the same in terms of usage and software. This provides you a cheaper opportunitiy to get started with Arduino boards.The microcontroller model of this board is the same as the original one (Atmega328). The only difference between microcontrollers is ther package. The original one has a DIP package but the clone one has an SMD package microcontroller.Despite being a clone one, there is a pin group (4x GND, 2x 5 V, 2x 3.3 V, 1x RX/TX, 1x SCL/SDA) near to the crystal oscillator and there are external pin holes allow you to solder male headers on the board too.Clone version of popular Arduino Uno R3 board. CH340 USB driver needs special driver, please check: http://www.microcontrols.org/arduino-uno-clone-ch340-ch341-chipset-usb-drivers/Only difference is USB driver other all purposes are the same.Arduino Uno SMD CH340 Driver FeaturesMicrocontroller: ATmega328POperating voltage: 5VInput voltage (recommended): 7-12VInput voltage (limit values): 6-20VDigital I / O Pin 14 (6 of them provide PWM output)PWM Digital I / O Pinlar: 6Analog Input Pin: 6DC current per I / O Pin: 20 mA3.3V Pin DC current: 50mAFlash Memory 32 KB (ATmega328P) which is used by the 0.5 KB bootloaderSRAM: 2 KB (ATmega328P)EEPROM: 1 KB (ATmega328P)Clock Speed: 16 MHzLength: 68.6 mmWidth: 53.4 mmWeight: 25 g
