Should Espruino be compatible with this board? (STM32F103C8T6)

I'm interested in Espruino and would like to play around with it, but I'd prefer a less expensive board. I saw this one here http://www.electrodragon.com/product/stm32-mini-dev-board-stm32f103c8t6-arm/ which is listed as having a STM32F103C8 for about $8 which would be a little easier to swallow. But, I don't see that CPU listed on http://www.espruino.com/Other+Boards so I'm just curious - should it work in principle?

If it is compatible, what would you recommend to use as a programmer? It has a microUSB plug on the board, and I also have an FTDI friend available - would either of those work?

Thanks and sorry for the cheep/noobish questions :)

Actually, I think I just figured it out. http://www.st.com/web/catalog/mmc/FM141/SC1169/SS1031/LN1565/PF164476 reports that the chip only has 64kb of flash, and I believe I recall reading that Espurino has trouble at 128kb, so that would make this a "no".

I'm afraid it won't fit in 64kB. Even at 128kB we're still having to cut out some features to make it fit in.

Seriously, if you just want to play around, don't make life difficult for yourself for the sake of a few dollars. Buy the proper board that'll just plug in and work right away.

If you really can't bring yourself to spend $39 (a lot of which goes to support the work we do on Espruino), buy an STM32F4 discovery board - but you'll spent significantly longer installing software and flashing it each time Espruino is updated, and you'll have a much harder time following examples and tutorials, as all the pins will be different.

Fair enough. Thanks for the quick confirmation :)
