Seeeduino V328

Vendor's Description: 

The Seeeduino 328 is the newest model of an Arduino Diecemila clone from Seed Studio. It is a fully compatible Arduino Diecemila board, evolved with SMD components. The actual version 2.12 is shipped with an ATmega328 processor including Arduino bootloader.


  • ATmega328 processor, 16MHz
  • 32kB Flash
  • 2kB SRAM
  • 1kB EEPROM
  • 14 digital I/O, 6 with PWM
  • 8 analog Inputs (2 more than Diecemila)
  • 5V or 3.3V operating voltage
  • Mini USB connector
  • 2 pin JST power battery connector


Differences vs Diecimila:

  • Duplicate digital IO to 100mil grid for prototype board compatibility.
  • Shrink componets height below female headers.
  • Easier access to buttons and switches.
  • Change Type-B USB port to Mini USB.
  • Replace 3.5mm DC power Jack to battery 2 Pin plug.
  • Reset and power indicator near RST button.
  • Auto-reset selection switch.
  • 3.3V Operating Voltage selection switch.
  • Pin out UART for FTDI232 bit-bang operation.
  • Pin out 2 extra ADC.
  • Optional capacitor for improving 3.3V output performance.
  • Re-route PCB
  • Pin out for I2C and sensors
