Arduino Nano V3.0 CH340 Chip

Description

Arduino Nano CH340 Chip The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.x). It has more or less the same functionality of the Arduino Duemilanove, but in a different package. It lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one. Specifications: Microcontroller ATmega328P – 8-bit AVR family microcontroller Operating Voltage 5V Recommended Input Voltage for Vin pin 7-12V Analog Input Pins 6 (A0 – A5) Digital I/O Pins 14 (Out of which 6 provide PWM output) DC Current on I/O Pins 40 mA DC Current on 3.3V Pin 50 mA Flash Memory 32 KB (2 KB is used for Bootloader) SRAM 2 KB EEPROM 1 KB Frequency (Clock Speed) 16 MHz Communication IIC, SPI, USART Difference between UNO and Nano The Arduino-Nano is very much similar to the Arduino UNO. They use the same Processor (Atmega328p) and hence they both can share the same program. One big difference between both is the size. UNO is twice as big as Nano and hence occupies more space on your project. Also, Nano is breadboard friendly while Uno is not. To program an Uno, you need a Regular USB cable; whereas for Nano, you will need a mini USB cable. The technical difference between Uno and Nano is shown below: Name Processor Operating/Input Voltage CPU speed Analog In/Out Digital IO/PWM EEPROM / SRAM[kB] Flash USB USART Uno ATmega328P 5V / 7-12V 16 MHz 6 / 0 14 / 6 1 / 2 32 Regular 1 Nano ATmega328P 5V / 7-12V 16 MHz 8 / 0 14 / 6 1 / 2 32 Mini 1 Package Includes: 1x Arduino Nano Documents: Arduino Nano Datasheet Related Products: Arduino Boards
