Hello,

I am in the process of learning my way around microcontrollers and designing an IOT device that will include a thumb keyboard. The font used will be an older one used on BBS systems and I envision holding control keys to utilize the upper area of the fonts for drawing.
As similar, I am aware that the esp32 lacks the pins demanded to program a keyboard so I am thinking a keyboard controller chip would be needed. Does anyone have a recommendation on what I should use?

I looked up many but they feel to be more fit for a laptop and apparently preprogrammed.

Thanks & Regards
