The Arduino UNO SMD is a microcontroller board based on the ATmega328P. It is an upgraded version of the classic Arduino UNO board, with surface-mount technology (SMD) components that make it smaller and more compact than the original. It is a great choice for anyone looking to create simple electronics projects or for those who are new to programming and electronics.
The board features 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 can be programmed with the Arduino software (IDE), which uses a simplified version of C++.
Features of the Arduino UNO SMD:
- Microcontroller: ATmega328P
- Operating Voltage: 5V
- Input Voltage (recommended): 7-12V
- Input Voltage (limit): 6-20V
- Digital I/O Pins: 14 (of which 6 provide PWM output)
- PWM Digital I/O Pins: 6
- Analog Input Pins: 6
- DC Current per I/O Pin: 20 mA
- DC Current for 3.3V Pin: 50 mA
- Flash Memory: 32 KB (ATmega328P) of which 0.5 KB used by bootloader
- SRAM: 2 KB (ATmega328P)
- EEPROM: 1 KB (ATmega328P)
- Clock Speed: 16 MHz
- USB Connection
- Power Jack
- ICSP Header
- Reset Button
With its compact size and ease of use, the Arduino UNO SMD is a popular choice for hobbyists and students who are just starting out with electronics and programming. It is also a great choice for creating simple DIY projects and prototypes.
