The Arduino UNO R3 SMD is a popular and versatile microcontroller board based on the ATmega328P microcontroller. The SMD (Surface-Mount Device) version features the ATmega328P microcontroller in an SMD package, offering the same functionality as the traditional UNO R3 but with a more compact design. It is widely used for a variety of projects, from simple experiments to complex prototypes.Key Features:Microcontroller: ATmega328P in SMD packageOperating Voltage: 5VInput Voltage (recommended): 7-12VDigital I/O Pins: 14 (of which 6 provide PWM output)Analog Input Pins: 6Flash Memory: 32 KB (ATmega328P) of which 0.5 KB used by bootloaderSRAM: 2 KB (ATmega328P)EEPROM: 1 KB (ATmega328P)Clock Speed: 16 MHzUSB Connection: Standard USB-B for programming and communicationPower Jack: 2.1mm center-positive barrel jackICSP Header: For in-circuit programmingReset Button: For easy reset of the microcontrollerTechnical Specifications:Microcontroller: ATmega328POperating Voltage: 5VInput Voltage (limits): 6-20VDigital I/O Pins: 14 (6 PWM)PWM Digital I/O Pins: 6Analog Input Pins: 6DC Current per I/O Pin: 20 mADC Current for 3.3V Pin: 50 mAFlash Memory: 32 KB (ATmega328P) of which 0.5 KB used by bootloaderSRAM: 2 KB (ATmega328P)EEPROM: 1 KB (ATmega328P)Clock Speed: 16 MHzLength: 68.6 mmWidth: 53.4 mmWeight: 25 g
