====== Engenius ENH-200 ======

The Engenius ENH-200 is a 2GHz 802.11bgn mesh device suitable for outdoor deployments.

===== Hardware =====

  * AR7240 %%SoC%%
  * 2 x 100MBit ethernet ports
  * 32MB RAM
  * 8MB NOR flash
  * 10dBi panel (directional) antenna

The 4 port serial header has an arrow silk-screened above one of the pins (closest to the wifi antenna connectors at the far edge of the board.) Take that as pin 1:

  * Pin 1 - 3.3v (normally don't need to connect)
  * Pin 2 - GND
  * Pin 3 - TX
  * Pin 4 - RX

===== Build instructions =====

===== Unimplemented features =====

The LEDs aren't yet linked into the GPIO setup.

The panel is apparently dual-polarity and can be changed by reprogramming the antenna switch register.

#define ALL0258N_SWITCHCOM_HORIZONTAL  0x09a00210
#define ALL0258N_SWITCHCOM_VERTICAL    0x0a900120
