FRAM orientation? I can't tell from the pin out diagram of the Weather Pi Board which direction the Fram module is supposed to face. I could guess but guessing isn't my preferred way of wiring. So far as I can tell for certain there's just no clear indication which of the jumpers is ground, power, etc. There are other pins in the general vicinity. One may be marked Vcc but it's nearly impossible to know for sure. The FRAM module is clearly marked.
More room in the vicinity of the Grove Sunlight Connector One other revision I would consider is more room where you plug in the sunlight grove connector. If you use buckled grove connectors (which I prefer) the Grove sunlight buckle is so close to the other Arduino type connectors, that I fear breaking the solder connection on the grove connector. That's already happened on a couple of your Grove boards.
Can I mount the whole station on a copper covered board? I do like the patina of copper. I would like to mount the weather station on a piece of copper covered wood. But, I am worried about potential bad electrical effects of that on the weather station. I would, of course, ground the copper. Still, induction etc. worries me a bit. Any thoughts?
Appreciate your comments! We will put them in the hopper for the next revision of the board.
FRAM: Yes, it is poorly marked. Pin 1 is to the left (right next to the JP6 label) and is VDD on the FRAM board. Pin 8 to the right is A0.
Grove Connectors: Yes, there needs to be more room. We have noticed this too. We cut off the buckle with a wire clipper. Friction fit was good enough.
Copper Cover: No problem with that. It will be fine. However, if you are using WiFi and/or a WXLink, you will change the receiving and transmitting patterns. We had a customer in Columbia Falls with a lower power OurWeather ESP8266 actually dramatically reduce his WiFi range by using a copper sheet.

One other note regarding the Grove Sunlight / IR / UV I2C sensor. It would be nice, if possible, to have the Grove Receptacle on the side of the board opposite the light sensor. Here's why I think so (and I'm open to other options): It seems to me that the actual sensor (photocell?) should be as close to the outside of the enclosure as possible, so as to be able to measure maximum ambient light. The Grove Receptacle (probably not the right name) - when the Grove connector is actually plugged in - leaves the photocell at least 1/2" (and maybe 3/4") away from the enclosure opening (unless you have another suggestion for mounting it to the enclosure). I think that distance significantly impedes the ambient light from reaching the sensor at full strength. On the other hand, if the Grove was on the side opposite the sensor, the board and photocell can be nearly flush against the enclosure, increasing the amount of ambient light on the sensor.
I do like the Grove connectors, but in this case, not sure it's the best option (unless there's a way to mount a Grove onto the edge of the board?). I suppose I can just unsolder the Grove connector and solder the wires directly where the Grove previously resided. But, if it's possible on a later revision to either use a edge mount (if there is such a thing) or place the Grove opposite the photocell, I think it would be a much more usable and effective module.
