Leonardo with Headers (Pack of 3)
Enhance your electronics projects with the Arduino A000057 Leonardo with Headers – available in a value 3-pack. Powered by the ATmega32u4 microcontroller, the Leonardo features native USB support, allowing it to emulate a keyboard, mouse, or other USB device without extra components. This makes it ideal for creating human interface devices (HID), custom controllers, and USB-based applications.
The board includes a USB connection, power jack for an AC-to-DC adapter, and 20 digital I/O pins – 7 of which can be used as PWM outputs and 12 as analog inputs. With built-in USB communication, the Leonardo simplifies development by handling both program upload and USB connectivity through a single port. The headers allow easy integration with shields, sensors, and external components, streamlining rapid prototyping and expansion.
Perfect for makers, educators, and developers, this 3-pack offers excellent value for multi-device setups, workshops, or classroom environments. Whether you're building interactive installations, automation projects, or custom input devices, the Arduino Leonardo delivers flexible, reliable performance in a compact form factor – backed by the trusted Arduino open-source ecosystem.
