My Maple Bacon appears to be bricked. After connecting the USB cable, it does not appear in the Tools -> Serial Port menu anymore. The reset button does nothing, no blinking lights...
Is it possible to recover this board? Thanks.

Moderatorzkarcher - One thing is to check that power is working. Have you got a multimeter?
If you have access to an oscilloscope, you might be able to detect the crystal oscillator, or the USB pins moving.
An option is to try uploading using the built-in serial bootloader, and discover if the chip will reset and run that bootloader. That will need a USB to serial adapter.
Another option is get an ST-LINK/V2 had try to get at the JTAG-SWD pins.
This needs several pieces:
- a GDB server ( https://github.com/texane/stlink )
- gdb (in the Maple IDE distribution)
- ST-LINK/V2 - the lowest cost is an STM32F0Discovery board, which is under $10
This is somewhat complex if you haven't used gdb. Texane's stlink has a program to upload over the ST-LINK/V2.More details are http://forums.leaflabs.com/topic.php?id=1293
