I have a Keyboardio Model01, which I have been using with no problems for the past 6 months, so I am pretty sure there is no problem with the switches themselves.
In the past week I have flashed the firmware from Chrysalis 0.6.0 and 0.6.2. Since updating the firmware, random different keys will repeat for 4 full lines or so. This happens every 5 or 10 minutessssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssssss
I did not input the above. The problem just occurred. Using Windows 10.
