This shield is good. However, it could be better: 1) The OLED display is difficult to read outdoors. 2) The placement of the power switch is problematic when used with a screw-on antenna (see photo). I need to use a tool or toothpick to access the power switch. The additional switch in the photo is wired to GPIO8 (LG-EVENT). I modified the RTK_Everywhere code such that, when that switch is pressed, a timestamp is recorded in the log. I then post-process the log to extract the positions at the times the switch was pressed.
