Demand for this controller is very little but still available so far.

I'll stop producing this controller when components in hand runs out. 30 pcs can be produced from the compoenents.

Updated firmware.  This change increase scan rate and disables debug print to accept fast key input .
Never got report from users but If you experience drop or transpose keys in fast typing try new firmware.

You can download from keymap editor or build from the latest source code.
