I uploaded a sample project to control your Roomba 530... Look in the cloud under sharing in the drop down list for Roomba 500 custom movement panel2

Don't forget to run the init script before first...

Thanks for that Richard. I did have a quick glance at your sample project the other day. Ordering new EZ-B tomorrow so I will have a good play around with this set up when it arrives.

I have updated it just now.... have another look if you want....

Thanks. I'll take a look now.

Hey guys.

I need a little advice. I've just ordered a little 5v inferred remote relay to power On/Off the EZ-B but I'm wondering about powering the relay itself. Could I use the 5v regulator from the shop and use the Ground and Possitive pins from the Roomba 530's comm port to connect to the relays input?

Of would something like a Buck Converter like this be a better option?

Thanks.

The power pins available via the Roomba 7 pin mini din will only support a power drain of 250 ma. If that is exceeded then the internal poly-fuse will trip. The fuse will auto reset once the overload is removed. You might want to use another voltage source and a 5 volt regulator.

@RobotDoc.

Damn, that's a shame. I suppose I can hook it up to the EZ-B's battery but I figured as the 530 is always on when charging, this would be ideal for the R/C relay and could be continually on as well. Oh well. Thanks for the heads up Doc.
