Prototype AB-1.12 availability
Børge Strand-Bergesen
I have routed the complete AB-1.12 prototyep board (just one trace
missing). This means I'm ready to order it from a PCB foundry in a day
or two. But before that I'd like to know who wants one. Regardless of
what you've written to me before, here is the procedure:
- Write an email to <a
href="mailto:borge....@gmail.com?subject=Order AB-1.12
Count">borge....@gmail.com</a>
- Subject: "Order AB-1.12 Count" where Count is the number of boards you want
- Wait for my confirmation with exact amount
- PayPal the correct amount to me
- Board arrives in the mail
You may wonder what this costs. A rough estimate tells me the price
per board will be around USD50-60 including shipping worldwide as a
letter. It is expensive because it includes custom XOs. But the more
buyers, the cheaper the boards. I plan to do this board as a one-off,
so now is your chance to get one.
Here is what the package will contain:
- Improved front and back plates in shiny red color, holes for SPDIF
and CAT5 on the front
- Interface to the same box and module as AB-1.1 (AB-1 module should also work)
- Three regulators designed by Demian and Oneoclock
- Room for PCM5102 where ES9023 used to sit
- Two loose Golledge XOs, 22.5792 and 24.576MHz
- Room for I2S output over CAT5
- Room for SPDIF output
- Room for ES9012/18 DAC chip, headers for PSU and IVC
- All headers (except module) on the same 2.54mm grid for easy veroboarding
I will update BOM lists etc. All components should be easily available
at DigiKey or similar.
Cheers,
Børge
