Re: Anyone used the ELEKITSORPARTS digital interface board? Opionons? #ubitx #digital

The 5v pad goes to the output pin of the 5v regulator on the arduino board, or your can do what I did and put a separate 5v regulator on the 5v and earth pads, bend the input pin back on itself and wire to 12v rail.
that way it is not adding to the load on the arduino reg, causing more heat.

So is this the only connection to the main board?  What is on the 5 volt pad?
