                                    I love the OpenCV part, though I'll

                                  So yeah, It needs to be beefy, and the
                                  ESP32 seems to be a nice candidate and

                                tell how many on this pinout) and plenty
                                of HS GPIOs for native or soft UARTs.
                                Having 2 CANbuses shouldn't be an issue
