Z-Wave USB Controller with best-in-class RF range Reference Design

Z-Wave USB Controller with best-in-class RF range Reference Application Design

The Z-Wave Alliance Z-Wave Reference Application Design (ZRAD) is a simple to copy, easy to modify, Open-Source Reference design of a Z-Wave best-in-class RF range device. ZRAD is not a product you can purchase, but anyone is welcome to manufacture and sell a product based on ZRAD. The objective is to accelerate Time-To-Market for Z-Wave products thru a simple to follow example with detailed step-by-step instructions. See the docs/ZRADTechDocs.docx file for more details and the Theory of Operation.

ZRADmini: common questions

What microcontroller does the ZRADmini use?

The ZRADmini is built around the EFR32xG23xxxxF512xM48, from the Silicon Labs family.

How big is the ZRADmini PCB?

The ZRADmini measures 34 × 94 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ZRADmini?

57 components, from 38 distinct parts. The full bill of materials is listed on this page.

Where can I download the ZRADmini design files?

From the drzwave/ZRAD repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ZRADmini design in my own project?

Yes, under the terms of its MIT license, which drzwave chose for the repository.

Can I test firmware for the ZRADmini without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Silicon Labs firmware against it before you order a PCB.
