Lots of people have asked me where I got the portrait layout keyboard. Here's the current situation:
There is no consistently produced version of the RF mini keyboard. I spoke to iPassport and they just make a batch when someone meet their MOQ. See: http://www.chinaimportal.com/blog/minimum-order-quantity-moq-why-it-s-required-by-chinese-suppliers/
The current version of the Pi-Palette shown uses a iPazzPort/Unisen KP-810-02 (http://ipazzport.com/en_productinfo.asp?id=152) it's not available in the West, but is in China:
Because of this I've made alternate files for both the bottom half and the keyboard cover so you can also use the iPazzPort/Unisen KP-810-05E, KP-810-05V, KP-810-05C:
So you have a total of four keyboard options depending on what's available where you are. Updated STL files are labeled accordingly.
