Hermes J16 Breakout Board


7 in stock



The HPSDR Hermes transceiver board has a 26-pin connector on the rear panel that provides access to several audio and digital signals that users may want to access when integrating the board into their complete station. These include PTT, amplifier key-out, and audio inputs and outputs, as well as digital inputs and outputs.

Since the connector is designed to interface to an IDC ribbon connector, getting to the individual signals is a bit messy. The Hermes Breakout Board (HBO) is designed to address that problem.

It is a very small (1.25 x 1.5 inch) board with a 26 pin connector on one end, and five 3.5mm (“1/8 inch”) stereo jacks on the other. These provide:

  • Right speaker output (Hermes already has a separate jack for the left speaker)
  • Headphone output
  • Line-level output
  • Line-level input
  • PTT In and Key Out

Headers on the board provide access to the seven open collector control outputs, which can be used to drive antenna switches or other control systems, as well as additional PTT and key-out points. Because of size limitations, the board does not provide access to the user analog or digital inputs, which are not currently supported in available software.

NOTE: The Hermes Breakout Board matches the 26 pin ribbon cable connector on the original TAPR Hermes and ANAN-10/10E boards.  It does not directly interface with the 25 pin D-SUB connector on the later ANAN radios.
