Arduino Nano CH340 Chip Board (Clone Version) – Compact ATmega328P Microcontroller Board for DIY & IoT Projects
Note: This is a clone version of the Arduino Nano. For guaranteed performance, durability, and official support, we recommend using the original Arduino. Learn More
The Nano CH340 Chip Board (Clone Version) is a compact and cost-effective microcontroller board based on the ATmega328P-AU chip — offering the same functionality as the Arduino Uno in a smaller, breadboard-friendly form factor. Perfect for space-constrained projects, this board delivers all the power of the Uno with USB connectivity via the CH340 USB-to-Serial chip.
Its compact size, compatibility with the Arduino IDE, and affordable pricing make it a great choice for students, hobbyists, and developers working on IoT, automation, and embedded projects.
Note: The CH340 driver may be required for first-time setup. If the board is not detected or shows upload errors, install the CH340 drivers or reflash the bootloader.
