DescriptionNano (Arduino Nano Compatible Atmega328p CH340) is based on famous Arduino platform and does all the functions of Uno, but with a smaller footprint.This development board provides small plate with the same powerful microcontroller. It is compatible with Arduino and ideal for fast prototyping and easy integration. It’s vital for your small project where you don’t need much of a pin-outs but the small size is very important to make it look good. The board equips a low-cost USB-Serial Chip that makes it less in price than Nano with FTDI USB-Serial Chip used on older versions of Arduino Nano.The Nano is a small, complete, and breadboard-friendly board based on the ATmega328 . It lacks only a DC power jack and works with a Micro USB cable instead of a standard one.The board can be powered via the Micro-USB connection, 6-12V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27). The power source is automatically selected to the highest voltage source.The size of board is only 43 mm x 18 mm, it comes with 6 PWM I/O from the total of 14 digitals I/O, 8 analog inputs, 16Mhz clock speed and 32kB of flash memory. It can be programmed directly from the Arduino IDE, using the Micro USB connection.Note: This board is a 100% compatible clone version with same design as Arduino Nano. It is not the original version which is made in Italy. CH340 chip might not work directly with some PC/Laptop, you will need some ch340 drivers.Specifications:Microcontroller: Atmega328PVoltage: 5VInput Voltage: 7V – 12VI / O pins: 14PWM pin 6 (out of 14 I / O)ADC pin: 8 (out of 14 I / O)Flash Memory: 32KB (2KB used by bootloader)SRAM:2 KBEEPROM:1 KBCurrent I / O pin: 40mA / pinCommunication: TWI, SPI and UARTOperating frequency: 16MHzDimensions: 45mm x 18mmMicro USBFeatures :1 pair of TTL level serial transceiver ports RX / TXUsing Atmel Atmega328P-AU MCUThere is a bootloader installed in itSupport USB download and PowerSupport for external 5V ~ 12V DC power supplySupport power supply by 9V batterySupport ISP downloadAutomatic reset during program downloadPower OK blue LED on the bottomGreen (TX), red (RX) and orange (L) LED 5V to AREF jumperAuto sensing/switching power inputSmall Micro USB for programming and serial monitorICSP header for direct program downloadStandard 0.1” spacing DIP (breadboard friendly)Manual reset switch
