BLE Key Compact in its black printed case, the 3.5 mm key jack at the end

BLE Key Compact has room for a rechargeable battery under the board. With the battery it works without a cable: Longpath shows the battery level, USB-C charges it, and after ten idle minutes it goes to sleep. The first press wakes it up again. Without the battery it runs on USB-C and ships anywhere we ship to; with the battery it ships within mainland Europe.

What it does

  1. 01

    No cable, if you like

    With the optional battery you key from the sofa, the shack or the train and charge it over USB-C like your phone. Without it, it runs on any USB-C charger or power bank.

  2. 02

    Battery level in the app

    With the battery fitted, Longpath shows how full it is and whether it is charging.

  3. 03

    Sleeps when idle

    After ten minutes without keying it sleeps. The first press only wakes it, nothing is sent.

  4. 04

    Your own key

    Any straight key or iambic paddle with a 3.5 mm stereo plug. Tip is dit, ring is dah, sleeve is ground.
