Arduino Nano Board R3 with CH340 chip without USB Cable

Arduino Nano Board R3 with CH340 chip

Based on the Arduino platform, the Nano R3 Board CH340 Chip without USB Cable does all the functions of the Uno, but has a smaller footprint.

Using Nano CH340 Soldered Board R3 Chip without USB cable is essential for your small project where you don’t need many pins, but the small size is very important to make it look nice.

In comparison to older versions of Arduino Nano with FTDI USB-Serial Chip, the Nano uses a low-cost USB-Serial Chip.

With the ATmega328 (Arduino Nano R3), the Nano is small, complete, and breadboard-friendly. It has more or less the same functionality as the Arduino Uno but in a different package. In addition to lacking a DC power jack, it uses a Mini-B USB cable instead of a standard one.

This device can be powered by a mini-USB cable, a 6-20V unregulated external power supply (pin 30), or a 5V regulated external power supply (pin 27).

Six PWM I/O are included from a total of 14 digital I/O, eight analog inputs, 16Mhz clock speed, and 32kB flash memory.

Please note:

The CH340 chip might not work directly with some PCs/laptops. You will need some drivers for the CH340 chip.
