1 pair of TTL level serial transceiver ports RX / TX
Using Atmel Atmega328P-AU MCU
Standard 0.1” spacing DIP (breadboard friendly)
The Nano Board R3 with CH340 chip without USB Cable chipboard is based on the famous Arduino platform and does all the functions of Uno, but with a smaller footprint.
The Nano Board R3 with CH340 chip without USB Cable is 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.
This Nano 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 Arduino is a small, complete, and breadboard-friendly board based on the ATmega328 (Nano R3). It has more or less the same functionality of the Uno 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.
