Arduino UNO R3 Clone CH340C – Compatible Development Board for Arduino by ADIY

The Arduino Uno R3-Clone (ADIY) CH-340C is a microcontroller board based on the ATmega328P and a clone of the popular Arduino Uno R3. It uses the CH-340C USB-to-Serial converter chip, which makes it more affordable compared to the original Arduino Uno. It offers similar functionality and is widely used for DIY electronics and programming projects.

Key Features:

1. Microcontroller: ATmega328P, running at 16 MHz.
2. USB-to-Serial Converter: CH-340C chip, which replaces the ATmega16U2 used in the original Arduino Uno R3.
3. Digital I/O Pins: 14 pins, of which 6 can be used as PWM outputs.
4. Analog Input Pins: 6 pins for reading analog signals.
5. Flash Memory: 32 KB (0.5 KB used by bootloader).
6. SRAM: 2 KB.
7. EEPROM: 1 KB.
8. Input Voltage: 7-12V (via the power jack) or 5V (via USB).
9. USB Interface: Micro-USB or Mini-USB, depending on the board version.
10. Compatibility: Fully compatible with the Arduino IDE and most Arduino Uno shields.

Differences from Original Arduino Uno R3:

• USB Chip: Uses the CH-340C instead of the ATmega16U2 for USB communication.
• Cost: Significantly more affordable, making it ideal for budget projects.
• Driver Requirement: The CH-340C chip requires specific drivers to be installed on your computer, which are widely available for Windows, macOS, and Linux.

Applications:

1. Prototyping: Ideal for developing and testing circuits.
2. DIY Projects: Used for home automation, robotics, and IoT applications.
3. Educational Use: Perfect for learning electronics and programming.
4. Sensors and Actuators: Interfaces with various sensors, motors, and displays.

Advantages:

• Cost-effective alternative to the original Arduino Uno.
• Compatible with most Arduino software and hardware libraries.
• Widely available resources and tutorials.
