Looking for an STM8 evaluation board with 6K of RAM

So far I have used an STM8L-discovery, but the 1K of RAM is not enough any more. I need 6K. Otherwise I just want an LED or two, some GPIO and a serial port.

Any recommendation?

P.S.: There is this STM8/128_EVAL bord. However the descriptions don't mention with which microcontroller it comes. The photo in the manual looks as if there was a ZIF socket for the microcontroller, so I would have to buy one separately, but the boards on ebay seem to have a microcontroller soldered.

The STM8/128 Eval board has a STM8S208MB micro-controller.

This part has 6 kB of RAM and 128 kB of Flash for your code.

This board is expensive and it offers more than you need (e.g. a CAN controller), so I think that It's cheapier to build a prototype board for a STM8S207x micro (which has no CAN controller, but has 6 kB of RAM), and use the STM8L Discovery board to program and debug your code through its SWIM interface.

Does the STM8/128 Eval have an integrated stlink, like the STM8L-Discovery has?

No, the STM8/128 Eval board has no integrated stlink.

You may connect the STM8L Discovery one to debug and flash your code.

For this reason, I suggested you to build your prototype board.

Well, building my own board takes time, and someone is selling STM8/128-EVAL boards below 40€ here in Germany, so the STM8/128-EVAL seems like a good option to get something running quickly to me.
