E-bay sellers don't have any docum, even Chinese.

It contains some I2C eeprom and SPI flash - but to which SPI and I2C they are connected?

Also, I've tried to wire up a white ST-LINKv2 dongle to the SWD debuger contacts, but no success. According to this.

No software can see the target.

The board is alive. It has some test firmware from the factory that blinks LEDs and emulates a USB COM port to host. (but the port does not output anything and does not react to input at 9600 or 115200).

Wired up the SWD pins to a stand-alone ST-LINK/V2, no problems here.

Hello Mr. Avogadro (or still Clive?)

Have you wired the reset and SWO to the debugger tool?

Still cannot get it working...

VDDA/VREF+ isn't bypassed with any capacitors! They are not even able of copying reference design.

Buttons also could be debounced...
