The SainSmart Leonardo is a microcontroller development 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 microUSB connection, a power jack, an ICSP header, and a reset button.
Another faithful reproduction by SainSmart. The Leonardo is different than other Arduinos in the way it connects to the computer. It has USB code in the ATmega32U4 that replaces the FTDI USB chip, or the external ATmega16U2 USB converter from the Uno R3. It can appear to be a serial port, or an HID class USB device.
