4Pcs for Nano V3.0 ATmega328P Nano Board CH340 5V 16M Micro USB Microcontroller Board with PIN Headers Pin Unsoldered Compatible with Electronics Development Board Nano 328P Nano 3.0

• The Nano for ardu-ino can be supplied with power via the mini-B-USB connection, a 6-20 V unregulated external power supply unit (pin 30) or a 5 V regulated external power supply unit (pin 27). The highest voltage source is automatically selected as the current source.
• The Nano has 8 analog inputs, each of which offers 10 bit resolution. By default, they measure from ground to 5 volts, although it is possible to change the high end of their range using the analogReference function. Analog pins 6 and 7 cannot be used as digital pins, some pins have special functions.
• It is the smallest, most complete and breadboard-friendly board. It has everything that Ardu&no / Genuino UNO (electrical) has, with more analog input pins and a built-in + 5V AREF jumper, compatible with Windows, Mac and Linux operating systems.
• More breadboard space: Nano has the breadboard capability of the Boarduino and the Mini-USB with a smaller footprint than both, giving users more breadboard space. It has a pin layout that works well with the Mini or Basic Stamp (TX, RX, ATN, GND on one side, power and ground on the other.
• This board not FT232 as an official board supports ISP download; Supports USB download and power supply.

Some pins have specialized functions: Serial: 0 (RX) and 1 (TX). Used to receive (RX) and transmit (TX) TTL serial data. These pins are connected to the corresponding pins of the CH340G USB chip. The Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Ardu-ino Nano3.x). It lacks only a DC power jack, and works with USB cable instead of a standard one. Package Include : 4 X Nanov board
