Lots of circuit boards form OSHPark, read to be soldered into awesome.

This proof of concept transceiver will be modularly constructed, with a backplane (pictured at lower right), and a plethora of modules (pictured at left) that will be inserted into edge connectors on the backplane. Once I have decided on a transceiver design, I will make a compact and inexpensive module that can be used with an Arduino, AVR, PIC, ARM, or most other embedded microcontrollers. Pictured at top right is a simple junction box that will be used to connect multiple devices together.
