ARDUINO UNO SMD -Atmega 328 - CH340 - Clone

Arduino UNO R3 Compatible Board is a low-cost, Arduino-compatible development board based on the ATmega328P microcontroller. It uses the CH340 USB-to-Serial converter for programming and serial communication with a computer. The board provides 14 digital I/O pins, including 6 PWM outputs, 6 analog input pins, a 16 MHz clock, USB connectivity, DC power input, ICSP header, and a reset button. It operates at 5V and can be programmed using the Arduino IDE, making it suitable for embedded systems, IoT prototypes, robotics, automation, sensor interfacing, and student projects. Key specifications: ATmega328P MCU, CH340 USB interface, 5V operating voltage, 7–12V recommended input, 32 KB Flash, 2 KB SRAM, 1 KB EEPROM, 14 digital I/O, 6 PWM outputs, and 6 analog inputs.
