Description Pro Micro ATmega32U4 5V 16MHz Arduino-Compatible Microcontroller | AuscomTech The Pro Micro ATmega32U4 is a compact, USB-enabled Arduino-compatible microcontroller board designed for projects that require native USB functionality in a small form factor. Based on the ATmega32U4 running at 5V / 16MHz, this board integrates USB directly into the microcontroller, allowing it to appear as a keyboard, mouse, joystick, MIDI device, or serial interface without external USB chips. It delivers Pro Mini–style performance with added USB capability, making it ideal for embedded, HID, and space-constrained designs. ⭐ Key Features ATmega32U4 MicrocontrollerRuns at 5V / 16MHz for reliable performance and full Arduino compatibility. Native USB SupportBuilt-in USB interface enables direct connection to a computer without a USB-to-serial adapter. USB HID CapabilityCan emulate keyboards, mice, game controllers, and other USB devices. Rich I/O OptionsIncludes digital I/O, PWM outputs, and analog inputs for flexible interfacing. ⚡ Onboard Power RegulationIntegrated voltage regulation supports external power input up to 12V DC. ️ Improved Protection & ReliabilityUpdated design includes corrected pin labelling, PTC fuse, diode protection, and safer RX/TX LED circuitry.
