Overview

Per the FCC photos...

• "EAP900-0.30 LFP" is silkscreened on the main board.
  • This device will likely be marketed by Senao as the EnGenius EAP900.
  • The 2G radio is using three Skyworks (SiGe) SE2576L / 2576L 2.4GHz PAMs.
• "EMP5608H" and "0.20 LFP" is silkscreened on the 5G wireless module.
  • The 5G module is using three Skyworks (SiGe) SE5003L / 5003L 5GHz PAMs
• This device appears to be using QCA9558-AT4A.

Probable used PSU(s)

The power supply shown in the FCC photos is a Powertron PA1024-2HUB / PA1024-2HU / PA1024-120HUB200.
