Google phone is the maximum representative of the Phoneblok movement developped inside of the ARA project.

Inside of the ARA platform the MDK (module development kits) defines the Reference Implementation for various design fetures. The MDK is a free and open Platform Specification and Reference Implementation that contains everything you need to develop an Ara module.


The MDK relies on a prototype implementation of the Ara on-device network using the MIPI UniPro protocol implemented on FPGA (Field Programmer Gates Arrays) and running over an LVDS (Low -Voltage Differential Signaling) physical layer. In other words a MIPI UniPro protocol stack for packet-switched data network on a flexible power bus.

Nevertheless, the subsequent versions will be built around a much more efficient and higher performance ASIC implementation of UniPro, running over a capacitive M-PHY physical layer.


This is implemented in an elegant industrial design that “glue” (in this case with  electropermanent magnets that provide chip to chip communications through capacitive coupling ) all the modules in an endoskeleton.
