This is the first manufactured revision of the LinHT PCB, now tagged as revA for reference and documentation.

⚠️ Important: We do not recommend manufacturing this revision. It contains several design flaws and limitations that make it difficult to assemble and impractical to use as-is.

Known issues in revA

  • USB-C charging does not work.
  • Power source design is incorrect:
    • 3.3 V is available only from the battery.
    • 5 V is supplied either from the battery or USB-C, but not consistently.
  • No power amplifier included.
  • Layout choices make the board harder to solder and debug.
  • Other minor issues affecting stability and usability.

Purpose of this release

This tag exists to preserve the history of the project and provide clarity on what was actually manufactured. Future revisions will address the above issues.
