It's pretty similar to 5.0 with just a few additions. However, there is a normally closed switch on 5.1 so with a small tweak, you could use a 5.0 BOM but the module wouldn't get any power until you shorted the 2 pins of the normally closed switch (SOT23-5 package).
Having said that, the software hasn't been updated yet to control the switch (which is fine; it's normally closed). Eventually, the software will have a feature that will detect when the module has locked up, and cause the switch to open for ~4.8s and then close again to basically "hard" reboot the module.
I hadn't released the BOM yet because neither Karlis or I had built any yet just to make sure they work...but of course they *should* work :) He's currently building some right now so we should know soon!
Did you see the post you bumped is one year old ?
Things have gone a little further since with integrated AMP board and little tweaking of the board layout. I suggest you to look at v5.3 you could find at
Or the latest one (v5.5 DPAK) where all components except Bluetooth chip (RN52) are on upper side and the voltage regulator is a DPAK one. It's available at
Which ever one you decide to go with, I'd be happy to provide the BOM.
Yes It's old, but did not find anything else. Found it very hard to find where the latest information is. The blog is not updated for a year, and facebook can't be the right place to look, where is the "home page" with all the latest information? Gerber files would be nice, usually orders from itead studio.
Guys, yeah, this blog hasn't been refreshed for a while. Been busy making new stuff and fixing some old to make sure there's something to write about at all. You should be using links provided in this post for v5.3 building reference.
