Product details of Nano Plus Developer Board with CH340 Chip Atmega328P for Arduino Compatibility: The nano development board is 100% compatible with for the Arduino and uses the same chips as the official version of for the ATmega328P and CH340 High Quality: Use high quality PCB raw materials and improved production techniques to ensure smooth edges and more reliable quality on every board Space saving: Nano has Boarduino and Mini + USB breadboard functions; the area is smaller than each, so users have more breadboard space Stability: The Nano can be supplied with power via a mini-B-USB connection, an unregulated external power supply (pin 30) of 6-20 V or an external 5 V power supply (pin 27). The power supply is automatically selected as the highest voltage source

Compatibility: The nano development board is 100% compatible with for the Arduino and uses the same chips as the official version of for the ATmega328P and CH340

High Quality: Use high quality PCB raw materials and improved production techniques to ensure smooth edges and more reliable quality on every board

Space saving: Nano has Boarduino and Mini + USB breadboard functions; the area is smaller than each, so users have more breadboard space

Stability: The Nano can be supplied with power via a mini-B-USB connection, an unregulated external power supply (pin 30) of 6-20 V or an external 5 V power supply (pin 27). The power supply is automatically selected as the highest voltage source
