* This was the source of some confusion and later the cause of the discontinuing of the kit and chip series

• The main chip is the XS1-U16A-128-FB217, it have 2 cores or, as advertised, "slices".

  • One of the slices runs the firmware to act as the programmer and debugger.

  • The other slice receive your code and act as the target chip. So it is show in the programming environment as of a simpler model.
