Roomba Pre-Defined Controls Via D0 On Ezb(4)

Are the pre-built controls within EZB going to be able to utilize any other UART ports or hardcoded to use D0 only on the new EZB(4) ?

Uart Port Voltage

Looking at the EZB spec sheet the UART TTL Voltage Level (input/output) is listed at 3.3 volts. I am going to connect that port to a device that uses 5V TTL for communicating via serial. I believe I would have to use a bidirectional logic level converter. Am I correct? Thanks

Continuous Servo Direction Change

So I am sure someone else has this some place ( i cant find it ) but I am just getting started with my EZ B (super fun btw) but I am having a silly issue getting the 360 servo to change direction i have the panel up but when I hit other arrow it does not switch... I can only get it to go one direction and stop... both arrows send it in same...

Wifi Connection

hi there, my EZ B is not showing up on my systems WIFI serch, why is that?

Servo Speed

I have two questions #1 - what are the values that make the continuous rotations servos go slow? For example 90 is to fast but I can seem to figure out what the range from real slow to real fast is. #2 - could someone provide me an example script that would drive the robot forward at the speed determined by a value in a script. Thanks.
