4.6 Power
The Z-Wave Module can be powered by either 3.3V or 5V by the Application Module. If powered by 5V a
5V-to-3.3V DC/DC converter must be mounted on the Z-Wave Module. As indicated in Table 7 the power
supply must be quite stable, so it does not create noise in the noise circuitry, resulting in reduced RF
sensitivity.

4.7 Antenna
In order to implement the Z-Wave Module in various products different types of antennas can be
implemented to get the best RF performance, i.e. range and reliability. The following antennas can be
implemented:
implemented to get the best RF performance, i.e. range and reliability. The following antennas can be
implemented:
• PCB Antenna (low cost, already integrated on the PCB)
• Wire/brace Antenna
• Whip Antenna
• Wire/brace Antenna
• Whip Antenna
The PCB antenna can be disabled by removing a resistor and the wire (or brace) antenna can be
implemented by soldering the wire directly onto the Z-Wave Module. Alternatively a SMA connector can
be mounted in order to mount a Whip antenna, either directly or via a coax cable.

Z-Wave Module Programming
The ZM1220 Z-Wave Module is programmed using the SPI interface, RESET_n and the program enable
signal PROG_N (see section 0). For programming instruction and recommended programming tool(s)
