wsnedi
The wsnedi daughter board is a collection of two radio transceivers and an MSP430 chip. The MSP430 can optionally be used to control the sensors on the platypus and the radio transceivers. Additionally level shifters are included to make the busses compatible with the Edison. See the schematic for more details on the hookup and wiring with this board. Please note that this board will be available next week.
We will now look at each component and its wiring to the MSP430 and Intel Edison.
datasheet It's an ultra-wideband wireless transceiver, capable of providing indoor localization with an accuracy of 10cm. It is connected via the SPI bus to both controllers. An Arduino driver is available here. Decawave also provides reference implementations. For the full datasheet and reference implementation you need to register at decawave.com or use http://bugmenot.com.

datasheet. A standard sub-ghz module that works on the 868MHz sub-band. This is less crowded than the 2.4GHz band and provides better propagation characteristics. A Linux driver is available here.

datasheet. An ultra low-power µC is included on the WSNEDI that can optionally be used instead of the Edison.
It's only connection to the outside is via the JTAG header, pin-out found on the schematic.
