Nano 3.0 ใช้ชิฟ CH340G USB Type-C พร้อมสาย (arduino-compatible board) Nano v3.0

ตัวเลือกที่ดีมากสำหรับลูกค้าที่อยากลดขนาด arduino โดยยังคงความสามารถไม่ด้อยไปกว่า Arduino uno
แถมด้วย USB type-c ที่ลดขนาดพอร์ตลงให้กะทัดรัดต่อการใช้งานจริง ในเวอชั่นนี้ขา pin ได้ถูกบัดกรีไว้แล้ว
ลูกค้าสามารถเสียบเข้ากับ PC และโหลด driver ที่จำเป็นก็สามารถใช้งานเขียนโปรแกรมด้วย Arduino IDE ได้ทันที

Arduino Nano Pinout (เลขขา arduino nano)
Power
The Arduino competible Nano can be powered via the USB Type-C connection, 6-20V 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.
Memory
The ATmega328 has 32 KB, (also with 2 KB used for the bootloader. The ATmega328 has 2 KB of SRAM and 1 KB of EEPROM.
Input and Output
Each of the 14 digital pins on the Nano can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. They operate at 5 volts. Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms. In addition, some pins have specialized functions:
- Serial: 0 (RX) and 1 (TX). Used to receive (RX) and transmit (TX) TTL serial data. These pins are connected to the corresponding pins of the FTDI USB-to-TTL Serial chip.
- External Interrupts: 2 and 3. These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value. See the attachInterrupt() function for details.
- PWM: 3, 5, 6, 9, 10, and 11. Provide 8-bit PWM output with the analogWrite() function.
- SPI: 10 (SS), 11 (MOSI), 12 (MISO), 13 (SCK). These pins support SPI communication, which, although provided by the underlying hardware, is not currently included in the Arduino language.
- LED: 13. There is a built-in LED connected to digital pin 13. When the pin is HIGH value, the LED is on, when the pin is LOW, it's off.
The Nano has 8 analog inputs, each of which provide 10 bits of resolution (i.e. 1024 different values). By default they measure from ground to 5 volts, though is it possible to change the upper end of their range using the analogReference() function. Analog pins 6 and 7 cannot be used as digital pins. Additionally, some pins have specialized functionality:
- I2C: A4 (SDA) and A5 (SCL). Support I2C (TWI) communication using the Wire library (documentation on the Wiring website).
