ATmega32u4 Leonardo Mini Compatible Arduino
This is a development board based on the Atmel ATmega32U4 microcontroller. For ease of use, we also provide a USB cable. Using the 16 MHz crystal oscillator, the microcontroller offers 8-bit resolution, 32 KB of flash memory, and 2.5 KB of RAM. A key advantage of the ATmega32U4 is its use of an integrated USB controller, which reduces the need for an external microcontroller and allows it to be connected to a computer as a keyboard or mouse.
