Theory of operation
A PC Engines APU2E4 SBC is used together with a LibreCellular CONIO-A board, to provide remote access to base station serial consoles, along with power and reset toggling, via connection to CONIO-B boards at the remote end.
The SBC also provides USB ports, which together with those provided by the CIHOST, may be used to drive cellular modems and control RF attenuators.
