A lot thanks to the the fine manual of WinKeyer IC and a famous open-source CW keyer project (K3NG CW Keyer), I could make a minimal WinKeyer clone prototype.
I tried to use a small-giant, ATtiny85. But its SoftwareSerial function couldn't handle the WinKeyer's slow baud rate (1200 baud). So I moved to anther small buddy, ESP-01S. And it gave me a good result.
I think I can make a small box that will not have any buttons or knobs, except just a pair of 3.5mm & USB socket. Specialized for the contest softwares.
