!! Overview
The KR01 is currently using up most of the available GPIO pins, with a bunch being used
by the TFT display (which is optional). In the future we may offload the four encoder
pins to the daughterboard containing the [ItsyBitsy M4 Express]. Most IO connections are
planned to use the [I2C] bus.
We're not currently planning to use the PWM (pulse-width modulation), SPI, Serial (UART)
or other GPIO features, just digital IO.
