Arduino Uno R3 Compatible Clone Board

Build, upload and test embedded projects quickly with the Arduino Uno R3 Compatible Clone Board, a practical development board based on the ATmega328P microcontroller and the standard Uno R3 form factor. It is designed to work with the Arduino IDE, making it suitable for beginners learning C/C++ microcontroller programming as well as experienced makers building sensor, automation and robotics prototypes. The board runs at 16 MHz and operates with 5V logic. You can power it directly from USB while programming, or use an external DC supply through the barrel jack or VIN pin for standalone operation. Like the classic Uno R3 design, it provides 14 digital input/output pins, including 6 PWM-capable pins, plus 6 analog input channels for reading sensors such as LDRs, potentiometers, soil moisture probes, thermistors and gas sensors. Communication options include UART, SPI and I2C, allowing easy connection to displays, motor drivers, wireless modules, real-time clock modules and many other Arduino-compatible accessories. Most Uno R3 compatible clone boards use a USB-to-serial interface such as CH340/CH340G for uploading sketches from a PC. On some computers, a CH340 driver may be required before the board appears as a COM port. The board includes the standard Arduino shield header layout, reset button, power LED, onboard regulator and ICSP headers, making it convenient for classroom experiments and modular prototyping. This Arduino Uno compatible board is a strong choice for LED blinking projects, line follower robots, relay control, data logging, home automation prototypes, keypad/display interfaces and sensor-based mini projects. Package includes one Arduino Uno R3 compatible clone board. USB cable, shields, sensors and power adapter are typically sold separately unless mentioned in the kit listing.
