MP1936 Audio DAC Production Record

[Philscrat]

Hi Wyqgyn
How did you decode the M72H035 mcu ?
The pcb you are offering is a replica of the ultra analog D20400 box ?

I can read all of his information by using a self-made I2S signal generator. It is the same data structure as the original version. You may not need M72H035 now, but you may not be able to purchase it. Because it is sold on Taobao. Many people don't go to Taobao.

Wiqgyn
how much for your personnal D20400 gerber files via mp ?

I just realized that one of the components is a PAL so the PCB without the program is useless

Because I am in China. Unable to sell them on EBAY. So it can only be used as a display. The mailing fee is quite expensive.

Some small parts like IC's, PCB's and small motors for cassette recorder, which I order from Germany in China, was often send via "Registered mail" in a small package - go to
https://en.wikipedia.org/wiki/Registered_mail#:~:text=Registered mail is a postal,a delivery attempt was made.
I always thought that this only worked for postcards and letters without any goods in them, but this isn't true.
Maybe this is a possibility for you to send your PCB's in other countries.

P.S.-II:
maybe the member of post #29 under

can say, from where one can get the datasheet of OKI's M72H035 (custom made for Ultra Analog).
