Z-Wave.Me RaZberry2 Z-Wave modul Raspberry Pi-hez

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 3.3 V and communicates using UART TTL signals (RX/TX). RaZberry is compatible with all models of Raspberry Pi.

The daughter card hosts a Sigma Designs ZM5101 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 U.FL connector for external SMA antenna.

The power consumption of the board is typically 18 mA at 3.3 V but can peak up to 40 mA when the chip is transmitting.

RaZberry supports Z-Wave Security S2 and Smart Start technologies.

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 to extend battery life time of battery-operated devices in the network
• Advanced statistics about network actual usage
• Allows switching frequencies from software

RaZberry comes with Z-Way software, but it is also compatible with all third party software that uses Z-Wave Serial API. There are firmwares for static controller (for Z-Way and most of third party software) or bridge (for Z/IP).
