Ok so I have a pretty simple ROS arduino sketch that requires a couple libraries that arn't too large. I'm trying to avoid having to have a separate arduino board connected to my Udoo. The sketch compiles fine on an Arbotix-M board, but it's too large for the onboard Leonardo. Should I get the Ultra instead of the Advanced? I could just plug the sensor into the I2C ports, but the Braswell pins don't support above 1.8 Volt logic. I know I can use a logic translator, which I could try, but I've heard the Braswell pins are slow and wouldn't work real-time. Anybody have any insight into this?
