Arduino Leonardo without Headers

Arduino Leonardo without Headers is a microcontroller board based on the ATmega32u4. It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller, but this Leonardo board does not include headers.

Features of Arduino Leonardo with Headers

 

  • Arduino Leonardo is a microcontroller board based on the ATmega32u4
     
  • It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs)
     
  • 16 MHz crystal oscillator
     
  • Micro USB connection
     
  • A power jack
     
  • ICSP header
     
  • A reset button
     
  • Contains everything needed to support the microcontroller
     
  • Connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started
     
  • Differs from all preceding boards in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor
     
  • Allows the Leonardo to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port
     
  • Also has other implications for the behavior of the board
     
  • This version of the Leonardo comes without headers
