The SainSmart Leonardo R3 is a microcontroller development board based on the ATmega32U4.

  • Microcontroller development board based on the ATmega32U4. 
  • 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs)
  • 16 MHz crystal oscillator,
  • microUSB connection, a power jack, an ICSP header, and a reset button. 
  • Power it with a AC-to-DC adapter to get started.  A battery may also be used, or it can get power from the USB port.

20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), 16 MHz crystal oscillator microUSB connection power jack, an ICSP header reset button.

DESCRIPTION

SainSmart Leonardo R3 provides everything needed to support the microcontroller; simply  power it with a AC-to-DC adapter to get started. 

ATmega32u4 has built-in USB communication, eliminating the need for a secondary USB processor. Leonardo can model as the mouse and keyboard, which greatly improves the applications
