Arduino Leonardo Board

ATmega32U4 Core with Native USB: Powered by the 8-bit ATmega32U4 microcontroller running at 16MHz, featuring built-in USB communication that allows the board to act as a native USB HID device (keyboard, mouse, or gamepad).

20 Digital I/O & 12 Analog Inputs: Offers 20 digital input/output pins (7 PWM output capable) and 12 analog input channels, providing expanded pin capability in a standard UNO footprint.

Onboard Micro-USB Connector: Utilizes a Micro-USB port for direct programming, serial data transmission, and power delivery, eliminating the need for a secondary USB-to-serial interface chip.

100% Arduino IDE Compatibility: Fully supported by the official Arduino IDE software for smooth code flashing, serial communication monitoring, and library integration.

Standard UNO Header Layout: Built with the classic UNO R3 form factor and header arrangement, ensuring compatibility with standard 5V Arduino shields and expansion modules.

PCB Construction: Built on a multi-layer FR-4 glass epoxy printed circuit board with clear silk-screened pin labels and sturdy female headers.

Power Supply Tolerances: Operates on 5V DC via Micro-USB or 7V–12V DC through the onboard DC barrel jack or VIN pin. Do not exceed 12V input to avoid thermal stress on the voltage regulator.

ESD & Handling Precautions: Practice standard anti-static handling procedures when touching exposed pins; disconnect power before making or modifying breadboard circuit wiring.

Environmental Limits: Operating temperature range is -10°C to +60°C. Keep protected from static discharge, conductive metal particles, and direct moisture.

Native USB HID Emulation Pitch: Market directly to enthusiasts and students looking to build custom PC macro pads, flight sim controllers, gamepads, and USB shortcuts.

Flexible Sensor Workhorse: Highlight the additional analog input channels compared to standard UNO boards, making it ideal for multi-sensor array projects.

Recommended Cross-Sell Add-ons: Pair with Micro-USB Cables, Solderless Breadboards & Jumpers, and OLED Display Modules.

Versatile Project Utility: Great choice for interactive media installations, custom human-interface hardware, DIY synth controllers, and robotics.
