Below is the best-guess set of features that a rooter hardware device would
include; this is a balance between good functionality, engineering feasibility,
and cost at the 1k or 10k production batch size:

 - Core
    - ARM SoC, Freescale i.MX6
    - Power management/regulator IC for SoC
    - 512MB RAM
    - No onboard FLASH, 8GB+ uSD card
    - FRAM chip for routing table persistance
 - WiFi
    - full-size miniPCIe slot for off-the-shelf dual-band card
 - 802.15.4 
    - all-in-one stm32w chip, trace antenna (?)
 - Ethernet
    - GigE switch chip w/ PHY, 5 ports
    - 4x LAN jacks with drivers for longer cable runs (w/ LEDs)
    - 1x WAN jack
 - Power
    - 5/12v regulator, ~1amp
    - Power connector
    - Reverse voltage diode
 - USB Host jack
 - USB mini jack for UART/JTAG/Mass storage (how? USB2 hub?)
 - Second SD or uSD connector (for expansion)
 - status LEDs and drivers (PWM from SoC?)
 - reset button
 - power switch
