Athena Revision Beta features a (more available) 64-pin STM32F401 microcontroller with some technical improvements, but same wide features as Revision Alpha: wide variety of layouts, removable USBC, JST connector for USB daughterboard support, JST connector for RGB daughterboard support, single-color LED backlight and RGB underglow available.

Technical improvements

  • Components were hand-picked so that the PCB could be assembled by JLCPCB's assembly service, excluding the ESD IC component and USBC connector due to their top-layer positioning (please note that component availability was assessed at january 29, 2022 and can change by the day);
  • Outlines were smoothed in some pieces;
  • New Joker64 topology;

Notes

  • The bill of materials released pertains to the Joker template configured for the F401 microcontroller. For clarification, read the Joker topology documentation.
  • This BoM also does not have the two JST connectors, one for the USB daughterboard and another for the RGB daughterboard
  • The 3D model STEP file contains both the JST connectors, which can be removed from the 3D model at the 3D software used (Fusion, SW...)
  • RGB level translator IC changed to SOT-563 from SC-70-6
