Board supply
Supply from battery
Board is typically supplied from battery. Li-Ion LIR2430 rechargable battery is
recommended. Capacity of 65 mAh gets to ZigBee board several hours of life. In the battery
operation mode SW1 is closed and SW2 is close on pins 3V3 and BAT. Have in mind there
is a protection against total battery discharge. When the battery voltage goes below 3.075 V
(typ.) the voltage supervisor activates the inhibit pin of voltage regulator.
Battery charging
Charging process starts automatically when USB (mini-USB) is connected. Let's remind
there are no data on the USB, it's used just for charging. SW2 must be close during
charging.
When charging red led LD12 is turned-on and green led LD11 turned-off.
When charged/done the green led LD11 turned-on and red led LD12 is turned-off.

The STR912, SN250, LIS302DL (MEMS), and STLM75 temperature sensor
communicate through the I
through SC1 I
The master can be either the dongle STR912 (STR912FAW34, STR912FAW42
and STR912FAW44) or the SN250 ZigBee network processor.
The SPI bus is shared between the STR12 and SN250. The SN250 is connected
to the STR9 dongle through SC2 SPI connector.
The dongle STR912 is configured to operate as a master by connecting the input
SSP0_NSS of the SPI bus to V
The SC2_SEL input is used to select the ZigBee module. It is connected to P80
pin of the STR9 dongle.
The board can be supplied directly by the STR9 dongle, please refer to
