it looks like the footprint and physical dimension graphics of the new RAK3172-F are faulty. They have just 5/6 pads on the left side when it should be 7. I am assuming here that the pinout graphic and the pinout table are correct because they indicate 7 IOs on the left side.
Thanks for flagging this. I will ask the documentation team to correct it.
However, the mechanical dimensions are the same as RAK3172.
The number of pins might not be correct, but the distance between the pins and the width of the pins are the same.
It looks like both the RAK3172-F Physical Dimension and RAK3172-F Layout were now updated to show all 7 pads on the left side with 6 mm spacing to the top and 3 mm to the bottom which looks correct.
