2
Power LED
LED to indicate the power switch is on and the 3.3V
power is present
3
On/Off Switch (SW5)

6
Restore Button (SW1)
Push button to restore previous firmware image if
pressed while the RESET button is released or power is
switched on, provided the PROGRAM button isn’t
pressed at the same time. If the PROGRAM button is
pressed, as well, the GS2K will enter program mode
with UART0 configured to 921K baud, rather than the
default 115.2K baud. This button is available for other
uses once the application code is running.

I/O Enable Jumpers (J10)
Peripheral Enable Jumpers. Install jumper to enable
signal on peripheral connector(s). Only install jumpers
as needed to avoid hardware conflicts.
