About this item

The Arduino Nano R3 with CH340 chip is a compact and versatile microcontroller board designed for embedded electronics projects. It features the ATmega328P microcontroller, providing 14 digital I/O pins (6 of which can be used as PWM outputs), 8 analog inputs, a 16 MHz clock speed, 32 KB flash memory, and 2 KB SRAM. This board operates at a 5V logic level and is breadboard-friendly, making it ideal for prototyping and development. Unlike the original Arduino Nano, this version utilizes the CH340 USB-to-serial chip, offering a cost-effective alternative for USB communication. Users should note that the CH340 driver may need to be installed on certain systems for proper functionality. The board can be powered via a mini-B USB connection, an external 5V regulated supply, or a 6–20V unregulated external power supply. It also supports ISP programming and features an ICSP header for direct programming. The board includes onboard LEDs for power (blue), TX (green), RX (red), and a general-purpose LED (orange). Please note that this version does not include a USB cable, allowing users to choose the appropriate cable for their setup. This Arduino Nano R3 with CH340 chip is suitable for a wide range of applications, from DIY electronics to professional prototyping
