The newest TinyMod comes with a jumper installed to make it boot into NKRO keyboard mode. If you remove the jumper and rebootIs the keyboard, it will be in TX Bolt serial mode. Without the jumper the keyboard should behave as TinyMods have always behaved. You won't notice any difference.

* Ubuntu 18.04 users should be aware that as of the writing of this post there a problem with Plover and NKRO on that platform where response is very, very slow. For the time being I recommend using TX Bolt serial for Ubuntu 18.04. And remember that in Linux no drivers need to be installed even for TX Bolt serial.
