I'd like to see an RPi that includes an Arduino (or maybe an ESP32) on board, with some way to easily connect things to that Arduino's GPIO pins, and with the Arduino programmable and controllable from the RPi.
This would let you run things that need real time GPIO access and real time interrupt handlings on the Arduino, and would also give you DAC and ADC.
