The ePico3801 consists of the ePico3801 body and the power adapter. The ePico3801 body
provides the LEDs, reset button, power port, and FE port. The ePico3801 supports the AC power
supply and Power over Ethernet (PoE) power supply, which require different power adapters.
2.3.1 ePico3801 Body
The ePico3801 body consists of the ePico board, RF subboard, and plastic case. The ePico board
is responsible for the main control of the system and the processing of baseband signals. In
addition, the ePico board provides power supply for the RF unit and controls communication.
The RF subboard receives, transmits, and processes RF signals.
2.3.2 Power Adapter
The ePico3801 can use the AC power supply or power supply from the PoE function. When the
AC power supply is used, the PoE power supply system is shut down automatically. When the
AC power supply is used, the ePico3801 needs to be configured with the AC/DC power adapter.
