The Nano V3.0 CH340 Chip with Mini USB Cable is a compact version of the popular Arduino Uno, offering the same functionality but in a smaller form factor.
Perfect for small projects where space is crucial, the Nano V3.0 is ideal when you don’t require many pin-outs but need a sleek, space-saving design.
This version uses a low-cost USB-Serial CH340 chip, making it more affordable than older Arduino Nano versions, which used the FTDI USB-Serial chip.
Based on the ATmega328 (Nano R3), the Arduino Nano is a small, fully functional board that is breadboard-friendly. It offers nearly the same capabilities as the Uno but in a more compact package. Unlike the Uno, it lacks a DC power jack and instead uses a Mini-B USB cable for connectivity.
The Nano can be powered through the Mini-USB connection, a 6-20V unregulated external power supply (pin 30), or a 5V regulated external power supply (pin 27). It automatically selects the highest voltage source for power.
Measuring just 43mm x 18mm, the Nano V3.0 with the CH340 chip features 6 PWM I/O pins out of 14 digital I/O pins, 8 analog inputs, a 16MHz clock speed, and 32KB of flash memory.
Note:-
- CH340 chip might not work directly with some PC/Laptop, you will need some ch340 drivers.
- This board comes with OLD BOOTLOADER buy it accordingly
