While see in documentation that use of external power supply (e.g. 24V) is usually preferred over USB suppled power. However, cannot find documented whether it is safe to be connected via USB to computer for sketch testing while also connected to 24V power. To not be able to do so (requiring other more elaborate sketch download techniques) would be quite inconvenient, and seems unnatural IMHO.
Please make this clear in the documentation.
Hi, thanks for the suggestion. It is perfectly fine to use both 24V and USB at the same time. The USB input has a diode to prevent power going in the wrong direction.
You can plug/unplug the USB while the sketch remains up and running.
USB only will power up the topboard and LCD, and you can upload sketches, but the I/O channels will not work without supplying 12/24V.
