16 Euros Arduino Leonardo Board is Now Available

Arduino Leonardo is a new Arduino board with a 16 MHz Atmega32U4, 2.5KB RAM, 32 KB of Flash memory, 20 digital I/O, 12 analog inputs and 7 PWM outputs. In this version the MCU takes care of USB communication with the host, whereas for Arduino Uno, a separate chip is required to take care of this, which makes Arduino Leonardo cheaper than Uno.

Here’s a summary of Arduino Leonardo specifications:

  • Microcontroller – Atmel ATmega32u4 @ 16 MHz
  • SRAM – 2.5 KB onchip (ATmega32u4)
  • Flash Memory – 32 KB onchip (ATmega32u4) of which 4 KB used by bootloader
  • EEPROM – 1 KB onchip (ATmega32u4)
  • Operating Voltage – 5V
  • Input Voltage – (recommended) 7-12V | (limits) 6-20V
  • Digital I/O – 20 pins
  • PWM – 7 channels
  • Analog Input – 12 channels
  • DC Current per I/O Pin – 40 mA
  • DC Current for 3.3V Pin – 50 mA

Watch the video to get an introduction to this new Arduino board, and see how it can emulate a mouse and keyboard. The Arduino team sees potential to create game controllers, and use it for automatic input such a filling an excel spreadsheet automatically with Analog input data for example.

The company provides the  schematics (PDF) and “reference design” files (EAGLE schematics + PCB layout), as well as instructions and code sample in Arduino Leonardo Guide.

Arduino Leonardo is available now for 16 Euros + VAT without header and 18 Euros + VAT with headers.
