OK
For HamShield 1.0 for Arduino
No audio on right channel. Need better doc on TRRS jack. Lots of web search to find schematic, should be included with doc.

Thank you for the feedback.
We have improved our documentation, including providing schematics and TRRS operation on our website.
For others concerned about no audio right channel:
The HamShield provides audio to the left channel, mainly for single ear use. A modification for binaural use (ie: mono audio for both ears), we have provided a how to on our website:

I am sorry that you were unable to find the schematics. If you click on design files, you can find them there. Here is also a direct link:
