+++ Supports Security S2 and Smart Start +++ Firmware for static controller or bridge (Z/IP) +++ Allows changing frequencies with software +++ option for external antenna
The RaZberry is a tiny daughter card that sits on top of the Raspberry PI GPIO connector not blocking the USB boards. It is powered by the Raspberry PI board with 3.3V and communicates using TTL signals (RX/TX).
The daughter card hosts a Sigma Designs ZM5202 Z-Wave transceiver module (a so called 5th generation Z-Wave module, an external 32 K SPI flash for network data and a PCBA antenna. Additionally two LEDs are used to indicate certain status of the Z-Wave controller chip. Beside the PCBA antenna there is an option to solder a whip antenna and a IPEX connector.
The power consumption of the board is typically 18 mA @ 3.3 V but can peak at 40 mA when the chip is transmitting.
Compared to the standard firmware design used by almost all Z-Wave transceiver hardware, the RaZberry Shield firmware offers several extensions and enhancements:
- Backup and recovery function including network topology
- Optimised transmitting queue handling to speed up transmitting process
- Firmware update from the OS level in the field
- Trusted Platform module applying strong encryption
- Extended Wakeup Notification
- Handling to extend battery life time of battery operated devices in the network
RaZberry comes in three different versions depending on the transmitting frequency used:
- ZMEERAZ2: Version for all frequencies around 868 MHz (like EU, Russia, India, default is EU).
- ZMEARAZ2: Version for all frequencies around 921 MHz (like Australia, Korea, Brasil, default is Australia)
- ZMEURAZ2: Version for all frequencies around 908 MHz (like USA; Israel, default is USA)
Please check what frequency range you need. You may need to change the frequency within the frequency group using a shell script tool or Z-Way. For more information about technical data an the different operating frequencies please refer to the RaZberry manual.
