- Pre-loaded with the Arduino (16MHz) Bootloader
- Operating Voltage: 1.8V to 5V
- Runs up to 20MHz with external crystal
- 32K of program space. 23 I/O lines, 6 of which are channels for the 10-bit ADC
The ATmega328 with Arduino Bootloader allows you to use Arduino code in your custom embedded project without having to use an actual Arduino board.
