24 GS2K-SKB-HW-UG-001278, Release 1.0
14 Light Sensor (U4)
Used to measure and report the light level. The light
level may be viewed with the TLS mobile app or a web
browser. See
GS2200M Starter Kit Board Sensors,
page 38 .
15 Temperature Sensor (U5)
Used to measure and report the temperature value. The
temperature value may be viewed with the TLS mobile
app or a web browser. See

Power Measurement Switch
(J21)
The switch selects between “Active” (coarse -
100mA/V) and “Sleep” (fine – 125uA/V) current
measurement. NOTE: This switch should be in active
mode for normal operation. The module cannot operate
normally with the switch in sleep mode. The switch
should only be switched to the Sleep position after the
module has entered deep sleep, standby or hibernate
mode to measure ultra-low power levels.
19 JTAG Connector (J8)
Use this port to attach a JTAG debug probe for
firmware debugging.
20
UART0 and UART1
Configuration Jumpers (J18)
Configuration jumpers for UART0 and UART1. Use
these jumpers to configure how the UARTs are routed to
the USB connector and the peripheral connectors. See
GS2200M UART Connector Pinouts, page 44 .
