First off, why center Platypus Platform on Parallax Propeller 2?
P2 has a fantastic amount of "Smart Pins" that can route high-speed data independent of the eight 32-bit 300MHz processors that themselves can independently, or cooperatively, deliver many other features desired on a multipurpose computing platform - such as, driving displays, networking, system management and console interfaces to itself and extended Feature Modules hardware/software components. The high availability of IO as UART (up to 2 MBaud), SPI, and GPIO allow a high number of Feature Modules to be connected to the central Management Module with a Propeller2.
Feature Module Interconnect (FMI) 2x6 pins oriented in this fashion...
| GND | SPI-OUT | SPI-IN | SPI-CLK | /SLEEP | 3.3V |
| GND | UART-TX | UART-RX | /RESET | ATTENTION | 5.0V |
