Meet the Vail Lite – Your Pocket-Sized Path to CW

Love Morse code but hate cable clutter? The Vail Lite is the smallest, simplest way to connect your favorite paddle or straight key to any computer. Just plug it into a USB port, connect your key with a standard 3.5mm TRS/TRRS cable, and you're ready to send CW on https://vailmorse.com, practice with learning apps, or key your favorite logging software.

What Makes It Special: Tiny & Mighty – Built on the Adafruit TRRS Trinkey, this thing is about the size of a USB stick. Seriously portable.

Built-in TRRS Jack – No soldering, no PCB, no fuss. Works with standard stereo/mono cable-equipped paddles and keys.

Sidetone Buzzer Included – Hear what you're sending with no latency! The included piezo buzzer is built in using the Trinkey's STEMMA QT connector.

Ready to Use – Ships pre-programmed and shrink-wrapped with the buzzer installed. Just unbox, plug in, and start keying.

Full Keyer Support – Iambic A/B, Bug, Ultimatic, Straight Key—all the modes you need, built right in. USB HID & MIDI – Works as a keyboard (Ctrl for dit/dah) or MIDI device for MIDI-enabled Morse code apps, web tools, and games.

Whether you're just getting started with CW or you're a seasoned op looking for a grab-and-go solution, the Vail Lite has you covered. Simple, functional, and perfect for throwing in your laptop bag.
