Great Idea and implementation, where can I buy one?

Where may I purchase a dozen facebit devices?

Unfortunately we don't have the funding to make a big batch of these to sell. If there's enough interest I may be able to set up a limited run. In the meantime you can feel free to place an order yourself using the release files provided in the repo--note the errata in the readme though!

Thank you very much for the reply Dr. Curtiss. You have a terrific little device there and it's a shame there is no funding. I have embedded software skills and hardware validation skills but, being retired, I don't have the skill necessary nor funding to marshal a batch through manufacturing. Please keep me in mind if a limited run does appear in the future. I shall readily volunteer time for the project.

@apcurtiss We are trying to fabricate the boards using the files can you please suggest us the modifications (rework) in the existing board, you mentioned some resistor values can we know the exact value changes
Thanks!

[apcurtiss]

@FoundryM the tagged release (here) already has the miscellaneous small fixes I mentioned in the errata. You should definitely look into replacing the microphone if that's of interest to you! And the battery connector as well.

@FoundryM if you don't mind me asking, what are you planning to use the boards for?

[FoundryM]

@apcurtiss We are going to develop Powered Air Purifying Respirator for that we thought to Use this boards for air quality check and use some other sensors can you please help us to test this module otherwise if you have already working model can you please share with us.
