Build custom macro pads, mechanical keypads, and game controllers with the powerful Arduino Pro Micro. Driven by the high-performance ATmega32U4 microcontroller, this board features native hardware USB communication. Unlike standard boards that need secondary converter chips, the Pro Micro can connect directly to your computer and emulate a keyboard, mouse, or joystick. This native HID capability makes it the ultimate, undisputed choice for DIY mechanical keyboard builds, streaming decks, and macro shortcut pads.Â
