The RaZberry Daughter Card

The RaZberry is a tiny daughter card that site 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; old RaZberry hardware was based on ZM3102 module - so called 3rd 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.

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

Compatible with new Model B+ and Raspi 2

RaZberry is compatible with old Raspberry Pi Model B as well as with new Model B+! We have not tested against the new Raspberry 2 but we don't expect problems.

Yesterday I received my Razberry, plugged it on my baseboard and was up and running. Great Work Guys! Saves me month of effort dealing with the low-level Z-Wave stuff.

Z-Wave Book

The new Book about Z-Wave (264 pages) written by Dr. Christian Paetz, is now available at or It mentions a lot of the UI elements of the current RaZberry demo UI and is a great documentation about Z-Wave in general.
