  • Support for external 5V ~ 12V DC power supply
Description
  • The Arduino Nano CH340 is based on the ATmega328P microcontroller, the same chip used in the Arduino Uno. It operates at 5 V and runs at a clock speed of 16 MHz, providing comparable processing power and capabilities.
  • Instead of the more common FTDI USB-to-serial converter, this board uses the CH340G chip to handle USB communication. The CH340 converts USB signals to serial data that the microcontroller can process. It is a cost-effective and reliable alternative, widely used in compatible Arduino boards.
  • The compact design of the Arduino Nano CH340 makes it ideal for projects where space is limited, such as wearable electronics, small robots, and embedded systems.
  • Like other Arduino Nano variants, it provides 14 digital input/output pins (of which 6 support PWM output) and 8 analog input pins (A0–A7). These pins allow easy interfacing with sensors, actuators, and other external devices.
  • The board can be powered either via the USB connection or through an external DC power supply (recommended input: 7–12 V) connected to the VIN pin. An onboard voltage regulator ensures a stable 5 V supply to the microcontroller and peripherals.
  • A reset button is included on the board, allowing the user to restart program execution. This feature is particularly useful for debugging or manually resetting the system before uploading new code.
  • The Nano CH340 includes standard pin headers for connecting external components and shields. These headers provide access to power, ground, and communication lines such as SPI, I²C, and UART.
  • Built-in LED indicators are provided for power (PWR), USB communication activity (TX and RX), and a user-programmable LED connected to digital pin 13 (L). These LEDs assist in debugging and provide visual feedback during operation.
  • The Arduino Nano CH340 is fully compatible with the Arduino Integrated Development Environment (IDE) and supports the same C/C++-based programming language and libraries as other Arduino boards. This makes it easy to program, integrate, and use in both educational and professional applications.
