An Arduino based SSPA display controler for HPSDR/Hermes familly This module controls
- cooling fan
- 4x40 lcd display and shuts down the Bias current while beeping in case of dificulties
This board and the associated firmware have been developped by ON7EQ.
Some code modifications have been made by John Melton for the Hermes familly.
The design of this board uses the generic output names used by all Hermes/Angelia boards and could directly be plugged on the Alexandrie control board
So far, NO SSPA and NO Reflectometer/Refl-fwd coupler have been designed. A multipurpose 33dB Tandem Match coupler is under development (for both VSWR/PWR measurement and predistorsion -aka "pure signal"- sampling)

true picture of the first prototype
Board's dimensions are oversized to fit the 5x10 and 10x10cm size of all board of the Hermes project under Kicad:
