• I have just been able to successfully connect a "Flipper Zero" (see https://flipperzero.one/) to my Mac with macOS 13.6.1 and let it act as a keyboard (although it wasn't explicitly recognized as such, but only as a generic device)

    Thus, microcontroller-based devices are principally able to act like a keyboard - it's just that the Espruino Puck doesn't...(not out-of-the-box, at least)
