@ terence - For 4 layer boards it’s usually 2 weeks.
So, I just priced all the components at a higher quantity and if I can get 25 pre-orders, then I will sell these mainboards for $39.95 + shipping!
Any takers?
@ munderhill - You are talking about your wifi version NOT a LoRa version correct?
@ terrence - yes, that price is for the WiFi version. The LoRa radio modules are more expensive than the WiFi module Ii use.
@ munderhill - Understood.
in for 1
@ munderhill -
In for one. Bill me PayPal.
@ munderhill - Me 2 …
@ munderhill - I will purchase one.
So, I’ll be getting the prototype boards from the fab this weekend and will build one. However, I found an omission that required me to redesign the layout. As well, I have decided on a name the IL-BETA is now the Iot Labs Mercury! It’s still the same size, now with a connector for the battery.
So, here it is!

Well with a name like that, make it two ! 
So, this is why we prototype. Got the boards for the Beta yesterday, built the board and it doesn’t work! After spending a few hours with it, I find that on the top layer, one of the polygon ground pours was shorting out the D+ power from the USB connector. Fault - PCB Layout software (sure, I guess I should have checked it). 
After that was resolved with an X-Acto knife, I find that one of the crystals was not connected to the G80! Holy crap, was I drunk when I designed this! Fault - Mine! :-[ I already knew this was not going to be the last iteration of this board, but wow! I did however get the board working! Please ignore the missing components and jumper. These will all be fixed on the IoT Labs Mercury.
Required blinky video is here.

@ munderhill - Isn’t sometimes that the nice part of the job ?
Having something broken, figuring it out why it doesn’t work and getting it fixed …
@ .Peter. - Nah, I’d rather have everything work the first time! 
So, after building a prototype of the IoT Labs Mercury I found that the Reset and Boot buttons were too small and/or inaccessible. So I have increased the length of the board by 0.25" and using larger buttons. I like this arrangement a lot better!

Yeah, keyboards has the same size all over due to finger size. Looks good!
So I just sent Mercury Rev 2 to the fab! :dance:
I also ordered a stainless steel stencil from OSH Stencils for the first time!
Fresh from the oven…
Button clearance is awesome!
Now some testing! :dance:
Really need to figure out how to solder the headers without making such a mess… :-[

@ munderhill - Get a flux pen. flux the contacts before trying to solder. use a thin gauge solder.

With a little jig, you could probably just put the headers in the oven, too.
FYI, you missed one.
