Table 10, page 38 lists the GS2200M SKB LEDs.
A.3 GS2200M Starter Kit Board Sensors
The SKB has two on board low power sensors. Both sensors are I2C based and both provide
an alarm signal such that they can wake-up the GS2200M module. The power supply for
the sensors (VSN) is selected to be 3.3V (always-on) or 3.3V_SW (switched by
DC_DC_CTL) using jumper J15. When 3.3V is selected, the sensors remain powered when
the GS2200M is in standby or hibernate mode.
Table 11, page 38 lists the GS2200M SKB sensors.
NOTE: For complete GS2200M module specifications, refer to the GainSpan
GS2200M WiFi Module Data Sheet.

LED SKB Description
Power D4 (Green)
Illuminates when 3.3V output of the switch
is powered. This LED can be disabled for
low power operation by removing the “LED
EN” jumper (J16).
UART TX D3 (Amber)
This LED flickers when the SKB is
transmitting on the serial port.
LED1 D2 (Green)
Software controlled LED. Note: The LED
does not draw any power when it is not
illuminated.
LED2 D1 (Amber)
Software controlled LED. Note: The LED
does not draw any power when it is not
illuminated.
