Product Information

The device ET-BASE AVR EASY32U4 or Arduino Leonardo compatible is an AVR board that can be used to develop an open source programing with C or C++ from Arduino. The ET-BASE AVR EASY32U4 uses the Microcontroller from AVR ATMEGA32U4 that has an internal USB PORT that can be connect directly to the PC’s USB PORT. The board is ready to use by just download the written program from your PC on to the board.

There are two ways to use this board.

  1. Use as Arduino Leonardo compatible: This board comes with pre-programmed Arduino bootloader so you can start using it as Arduino Leonardo compatible board. By using Arduino IDE and USB port for programming.
  2. Use as stand alone AVR development board: You can program it using ICSP connector on the board.
