Morse code lives on in the form of CW (continuous wave) transmission, which brings us to this Teensy-based CWmodem from Johan Holstein (aka PD0LEW).
The MRSC Signature features a custom PCB and aluminum enclosure, with various available RA8875 and HX8357D-based touchscreens. A USB keyboard can be connected as an input device, in addition to the typical paddle preferred by CW enthusiasts. A wealth of options and settings are available, which you can find in extensive detail on the project’s web page, along with more pictures and videos of the device in use.
