Victoria Day Sale
ends May 20th

Availability: In stock SKU: 26904


Arduino NANO V3 USB-C is based on the 32kB Atmega328 with 16MHz and a USB-C port with CH340 USB UART.

The module comes either with Atmega328P-AU or Atmega328PB-AU chip. The chips are compatible and will run the same code. The additional functions of the newer PB version are not used in Arduino IDE.

Headers are included but not factory installed.

– Atmega328P or PB-AU with 16MHz
– up to 8 analog inputs
– up to 20 digital I/O
– 6.2 to 15V DC operating voltage
– 1A max. load current on 5V output
– 3.3V output for auxiliary equipment like sensors
– Arduino boot loader installed
– I/O and ICSP headers are included
– WCH CH340G USB-TTL bridge
– USB-C port

The NANO V3 USB-C has 32 KB flash memory (2 KB used for the bootloader), 2 KB of SRAM and 1 KB of EEPROM. Each of the 14 digital pins on the NANO V3 USB-C 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 about 20 kOhms. In addition, some pins have specialized functions, like RX and TX. These pins are connected to the corresponding pins of the CH340G 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.
– 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).
– I2C: A4 (SDA) and A5 (SCL).
– AREF. Analog inputs reference.

We recommend downloading the required USB driver for your operating system from WCH official website.
