Here are the key features and details about this board:

ATmega32U4 Microcontroller: The ATmega32U4 is an 8-bit microcontroller from Atmel. It operates at 5V and runs at a clock speed of 16MHz. The ATmega32U4 has 32KB of flash memory, 2.5KB of SRAM, and 1KB of EEPROM. It is a versatile microcontroller with built-in USB support, making it suitable for USB-enabled projects.

Type-C USB Connector: The board features a Type-C USB connector as its primary interface for connecting to a computer or power source. The Type-C USB port is used for both power supply and USB communication with the microcontroller. Type-C connectors are reversible and can be plugged in either way.

Compact Form Factor: The Pro Micro is known for its small and compact form factor, making it suitable for projects with space constraints. It's often used in wearable electronics and small-scale embedded systems.

GPIO Pins: The board provides a set of GPIO (General Purpose Input/Output) pins, including digital pins, analog pins, and power pins. These pins allow you to connect various sensors, actuators, and other electronic components to the board.

Built-in USB Functionality: The ATmega32U4 microcontroller on the Pro Micro has built-in USB functionality, which means it can be recognized as a USB device by a computer without needing an additional USB-to-Serial converter chip. This makes it ideal for USB HID (Human Interface Device) projects like keyboard and mouse emulation.
