Two of mine landed this morning with the mail. Are you using the @Charles styled low power framework on this device? I guess it is similar to what we have built with Arduino Pro-mini and RFM95 on Charles’s PCB, possibility to remove LDO’s or LED’s? I am liking the broken out pins at a glance but have not even opened the static bags yet.
Any insights most welcome @BoRRoZ
