Hi Jay,

The board I'm using is the STM32F4VE, described here:

https://stm32-base.org/boards/STM32F407VET6-STM32-F4VE-V2.0

Cheap and available; generally about $14-15 from Aliexpress.

I've toyed with the STM32H750 board (very similar, but runs at 400Mhz;
the added cost didn't contribute anything toward functionality.

Your DG might well be Pertec-interface, but you can check that out with
Bruce Ray.

Oh, a word of caution is in order... With the chip shortage, a lot of
Chinese vendors are re-labeling GDS32F407 and CKS32F407 chips with the
ST logo and markings.  I've run into a few, but generally, they perform
as well as--and in some cases, better than, the real thing.

I'll put you on my mailing list...

All the best,
Chuck
