The version numbers are as follows:

  • black_F407VE; v2.3
  • black_F407ZE; v3.1
  • black_F407ZG; no version marked (quite old, the SD card is buried next to the TFT connector, not on the edge)

from black_f407ve.

I found an image on here which explains there is a Classic and Upgrade version, with different pinouts:

My 3x boards are:
STM32_F4VE V2.0 1509 - STM32F407VET6
STM32_F4XX V3.0 1606 - STM32F407ZET6
STM32_F4XX V3.0 1606 - STM32F407ZGT6 (same board as ZET6, different cpu)
Looking at the schematics pdfs that came with each, they are all using the Classic LCD pin layout.

I found these two on Taobao:

STM32_F4XX_Pro V2.0 SN:171115 - STM32F407ZGT6
https://item.taobao.com/item.htm?spm=a1z10.1-c-s.w4004-22466574640.28.27c77402l508PG&id=565218048000

STM32_F4XX V3.0 1606 - STM32F407ZET6/ZGT6
https://item.taobao.com/item.htm?spm=a1z10.1-c-s.w4004-22466574640.30.27c77402l508PG&id=523276050344

Note the different board layouts and the Pro version has silkscreen label New TFT.

Many thanks for the research - I was going nowhere!!
The image showing the two connection sets has given me all the necessary clues.
I pushed the pins 1, 2, 29 & 32 (the highlighted pins in the right-hand side) from the V2.3 VE board, plugged in the LCD and away it goes!
It's not mirrored as I thought after all, they have just rationalised the power, griound and reset connections. I can now use CubeMX to generate all the setup for the ZE or the VE board and my app (such as it is so far - just an LCD demo) works great on either.
