ATmega328 Micro USB Interface with CH340G UART
This Arduino Nano compatible module is a small, complete, and breadboard-friendly design. Designed around the ATmega328 which is the same as the original Arduino Nano 3. It has similar functionality to the Arduino Duemilanove but in a different package. It lacks only a DC power jack and works with a USB-C cable instead of the less common Mini USB port.
Operating Voltage: 5V DC
Input Voltage (recommended): 7-12 V
Digital I/O Pins: 14 (6 provide PWM output)
Analog Input Pins: 8
DC Current per I/O Pin: 40 mA
Flash Memory: 32 kB (2 kB used by Bootloader)
SRAM: 2 kB
EEPROM: 1 kB
Clock Speed: 16 MHz
This new design uses the modern Micro USB connector.
Note: This unit includes two headers of 15-pins and the six-pin expansion connector. These will require soldering onto the processor Nano board.
