Feasibility for supporting M5Stack Cardputer Kit (M5StampS3)

[shirogaku]

M5Stack Cardputer Kit has keyboard and using M5StampS3.
It will be much more easier to keyboard to enter passphrase and make key more secure.

Is it possible or hard to make support this hardware?

From my understanding, Only adding keyboard support is enough but I'm not sure.

Keyboard is attached via 74HC138 decoder.

This would also need to wait support for the ESP32-S3 chip is added. (See here: #93)
