HARD kart one-ESP32 board

this 1 ESP32 will have to do everything:

steering motor control,

pedal emulation (throttle control),

speed measurement (~4 rotary encoders),

communication with selfdriving PC,

?optical flow sensor?,

?some accel/gyro(s)?

then it'll probably need a double-checked pinout and maybe even a custom PCB.

This PCB will sit somewhere near the dashboard OR somewhere near the flow sensor (depending on whether 1Mhz I2C or 2Mhz SPI is more sensitive to long cables, and of course the placement of the optical flow sensor).
