8MHz requires changes in the BitCloud Software that normally runs at 4 MHz in order to extend the voltage range and
2.3. MeshBean2 Board Design
2.2.4. Silicon Serial for UID storage
UID (Unique Identifier) is HEX value, 8 bytes long. UID is used for setting unique MAC
address of the node.
UID is hardware-defined value. It is programmed into a chip (Silicon Serial Number
DS2411R+ by Maxim/Dallas) at the factory.
UID is unique, and cannot be overwritten. In order to ensure the presence of UID on the
board it is required to execute Hardware Test application (see Section 3.7 for details).
The MeshBean2 board contains the ZigBit 900 module, which operates as
ZigBee/802.15.4 transceiver. It also includes sensors, buttons, DIP switches, and a set of
interfaces.
The board provides the following interfaces:
Also, the board contains an internal voltage regulator to supply most of the components
with 3.6 V. This is needed if ZigBit’s MCU is to be run at 8 MHz
NOTE:
Normally ZigBit 900 module is powered directly by the batteries, USB or AC/DC adapter
(via protection circuitry); however, Jumper J2 (see Table 6) can switch ZigBit 900 to 3.6 V
supply.
See Figure 2 for the layout of MeshBean2 with external antenna. See also Figure 3 for the
board’s functional diagram.
