      Rotator controller (#27) · c0681976
      Agis Zisimatos authored
      
      
      * Update satnogs library.
      
      Add new footprints, 3d shapes and schematic components.
      
      * Updates in rotator controller.
      
      Add RJ45 for communication and power in (PoE).
      New dimensions of board (euroboard 100x80 mm)
      Embed the power supply to the board (WIP).
      Add pins for indicator LED and for rf switch (optional).
      Add additional pads for power in case that PoE (RJ45) isn't suitable.
      Updates in schematic and board wuth new library parts.
      
      * Add PCA9540B schematic component, I2C multiplexer.
      
      * Add fuse holder and stitching via.
      
      * Updates in PCB and schematic.
      
      Add digital and power ground planes (WIP).
      Connection of separate GND with zero resistor.
      Add I2C multiplexer.
      Finalize power supply of 12V.
      Change RJ45 to headers.
      Add RC filter (LPF) for end-stops.
      Add more dev-pins.
      Add filter in uC voltage input.

      * Fix silkscreen placement and zone cleanup
      
      * Use one GND bottom plane and GND areas in front
      
      Remove zero ohm resistors
      To avoid connection with GNDD directly with motor GND use keep out area

      * Add electrolytic capacitor, TVS-diode in PSU input
      
      Capacitor reduces the voltage ripple of input voltage (long cable)
      TVS-diode protect the PSU and all the board from surges and ESD events
