The Arduino Leonardo with Headers (A000057) is an 8-bit AVR MCU evaluation board featuring the ATmega32U4 microcontroller. This board offers 20 digital I/O pins, 7 of which can be used as PWM outputs and 12 as analog inputs, providing versatile connectivity options. It supports an Arduino R3 Shield interconnect system and operates at a clock speed of 16 MHz with a 5V logic level. It offers UART, I2C, and SPI communction along with 2.5KB SRAM, 32KB FLASH, and 1KB EEPROM. The Leonardo is fully compatible with the Arduino IDE, making it an excellent choice for both prototyping and development projects.
