Description
The Vail Lite is the smallest and simplest member of the Vail Adapter family – a plug-and-play USB CW keyer interface built on the Adafruit TRRS Trinkey (SAMD21). About the size of a USB stick, it ships pre-programmed with a piezo sidetone buzzer installed.
Features
- USB HID keyboard output (dit/dah)
- USB MIDI support for Morse apps and games
- Full keyer modes: Straight, Bug, Iambic A/B, Ultimatic and more
- Built-in 3.5mm TRRS jack and sidetone buzzer
- Truly plug-and-play – no drivers, no setup
Note: no buttons, audio jack, CW memory, radio output, or Button Hat support – step up to the Basic or Advanced for those.
Best for: practice on vailmorse.com, portable laptop CW, and travel use. Assembled and shipped by Brett (KE9BOS), a main contributor to the Vail project.
