Michael ★★★★★

Got this board for a MIDI controller project and the ATmega32u4 made it plug-and-play as a native USB device, no extra chips needed. The extra analog inputs were a nice bonus for adding a few more sensors. It's working flawlessly so far.

Emily A. ★★★★★

Used this Leonardo to build a custom USB keyboard with analog trimpot inputs, and the ATmega32u4's native USB handling made it plug-and-play in minutes. The 12 analogue pins were perfect for mapping multiple sensor values without extra hardware.

John ★★★★★

The 20 digital pins gave me plenty of room for a button matrix and LEDs, and the 16 MHz crystal kept everything running smoothly without any hiccups. It's the first board I've used where the ATmega32u4's native USB made setup feel effortless.
