Can anyone tell me if there is any noticeable difference between routing your Nextion screen via the USB port w/ttl
or soldering directly to the modem? Good, bad, no diff? still sucking power either way.
USB or Solder?
Re: USB or Solder?
If you plan to update the screen config (HMI / TFT file on the Nextion display) often, I'd use USB, if you don't plan to do that - I'd use the modem connection, usually makes for a more compact setup.
Re: USB or Solder?
Soldering direct to the MMDVM Board looks nicer! in builds! BUT using this method you need to know how to program the nextion commands for the screen! as they are different to using the TTL USB adapter...
