Arduino Nano V3.0 CH340 Dev Board (Unsoldered) w/ USB Cable

Description

The Nano V3.0 CH340 development board serves as a highly compatible and cost-effective alternative to traditional Arduino Nano boards. It leverages the robust Atmel ATmega328P-AU microcontroller, providing 14 digital I/O pins (including 6 PWM outputs) and 8 analog inputs, alongside 32KB of flash memory for program storage. Its compact size, significantly smaller than the Arduino Uno, makes it an excellent choice for projects where space is at a premium.

This version integrates the CH340 USB-to-serial chip, which contributes to its lower price point while maintaining reliable communication. Users should note that specific CH340 drivers might be required for seamless operation on some PC/Laptop systems. The board offers flexible power solutions, allowing it to be powered via the Mini-B USB connection, an unregulated 6-20V external supply, or a regulated 5V external supply, with automatic selection of the highest voltage source. An old bootloader is pre-installed, facilitating easy program uploads via the Arduino IDE.
