IMPORTANT NOTES:
Any other position of jumpers J2 and J3 or their omission may cause permanent
damage of the hardware.
Powering the board without J1 jumper and ammeter connection between clamps CM+ and
CM- may cause a permanent damage of the hardware.
When making connection to the PC’s serial port through the Expansion slot consider the
pinout as indicated below in Table 8.

The board includes 2 buttons, 3 DIP switches, one Reset button that generates a
hardware reset signal, 3 software-defined LEDs (green, yellow and red) and a LED
indicating powering the board from the USB. Any of onboard buttons, DIP switches and
LEDs can be controlled by an embedded application running on a ZigBit 900.

Description
ZigBit 900 is powered by primary source (battery,
USB or AC/DC adapter).
ZigBit 900 is powered by 3.6 V internal voltage
regulator.
Description
The board will use serial port (available in the
Expansion slot) for connection to the host.
The board will use USB for connection to the host.
Description
In this position, the ZigBit 900 module is not
powered while remaining parts of the board are
powered. This position is used to measure current
consumption of the ZigBit 900 module (see
Section 3.8).
