Product Overview
The Z-Uno Module ZMEXZUNOM is a Z-Wave module that implements the Z-Wave protocol and allows custom user code execution. It is an ideal solution for home control applications such as appliance control, heating control, access control, AV control, building automation, energy management, lighting, environmental and security sensor networks in the "Internet of Things" ?.
The Z-Uno Module provides GPIO, ADC, PWM, UART, USB, SPI, I2C, and OneWire interfaces accessible from user code.
Z-Wave wireless communications and network management are handled by the module's internal firmware. It operates with Z-Wave gateways and directly with other Z-Wave devices.
The Z-Uno Module is firmware compatible with the Z-Uno prototyping board (ZMExZUNO), facilitating prototyping on breadboards.

Applications

Language Reference
The Z-Uno Module compiler, Z-Uno uCXX, supports C and a slightly limited C++ programming language. Peripherals are accessible via special functions or libraries in an Arduino style. Some Arduino libraries may be compatible, while others might require porting. User code must be compiled with special Z-Uno Core Libraries. Installation instructions are available at z-uno.z-wave.me/getting-started.
Z-Wave features, such as channels and associations, are defined within the User Code. Getter and setter (callback) functions are used for handling incoming events from the Z-Wave network.
For detailed information on channels, associations, getters, and setters, refer to the Z-Uno Quick Start Guide: z-uno.z-wave.me/files/z-uno/QSG/Z-Uno-Quick-Start-Guide.pdf.
The full language reference is available at z-uno.z-wave.me/Reference/.
Software Structure
The ZMEXZUNOM includes a pre-loaded user code bootloader, which can be upgraded via USB or OTA (Over-the-Air). The module supports four different bootloaders, depending on the frequency and desired security scheme.
The Z-Uno firmware comprises four main parts:
- User code: Also known as a sketch, written in a simplified C language. It is loaded using Z-Uno tools and controls all device pins and logic.
- Bootloader: Configures the Z-Wave Application layer based on user code settings, defines channels, associations, and power management modes. It handles network inclusion and rescue mode, calling user code callbacks for Z-Wave packets.
- Z-Wave Application layer: Maps Z-Uno Channel capabilities and Association groups to Z-Wave Command Classes, ensuring full Z-Wave Plus protocol compliance. It provides features like Over-the-Air or USB firmware upgrades, AES encryption, radio power metering, battery monitoring, and Z-Wave network management.
- Z-Wave Network layer: Based on Silicon Labs 6.7x SDK, it manages network and radio layers, establishing a reliable mesh network. It calculates routes, prepares, sends, and receives radio packets.
User code space size varies based on the security level and operation frequency:
| Available User code size | Security | Frequency |
|---|---|---|
| 30 kB Flash, 2 kB RAM | Non-secure or Security S0 ? | EU/US/RU/IL/ANZ/BR/CN/IN |
| 30 kB Flash, 2 kB RAM | Non-secure or Security S0 ? | JP/TW |
| 6 kB Flash, 2 kB RAM | Security S2 ? | EU/US/RU/IL/ANZ/BR/CN/IN |
| 6 kB Flash, 2 kB RAM | Security S2 ? | JP/TW |

Programming and Operation
Programming
The ZMEXZUNOM is programmed using C/C++. The user code is compiled with the special Z-Uno uCXX compiler, freely available from z-uno.z-wave.me. The Arduino IDE can be used for development and flashing, or alternatively, console tools provided with the Z-Uno software package can be used.
The Z-Uno Module can be programmed via:
- USB: Using USB_DM, USB_DP, GND, and a 3.3V power source.
- Over-the-Air (OTA): Via any OTA-capable Z-Wave controller.
Both User Code and Bootloader can be upgraded. After programming User Code with changed Z-Wave capabilities, Z-Uno Modules must be removed from the Z-Wave network and added again to apply the changes.
Diagram Description: A diagram illustrates the Z-Uno Module programming connection via USB, showing the VCC (5V), USB_DM, USB_DP, and GND connections to the module.
Z-Wave Features
The Z-Uno Module implements the Z-Wave Plus protocol. All mandatory Z-Wave Command Classes are automatically included. The module's features are presented in the Multi Channel Command Class and corresponding Z-Wave Plus Role Type, depending on the type and number of channels.
To add or remove the Z-Uno Module from a Z-Wave network, use the Learn Mode sequence on pin 23 (Service Button pin). A triple click is required if a button is connected to this pin. Alternatively, the zunoStartLearn function can be used within the User code.
Diagram Description: A diagram shows the timing sequence for Learn Mode: a 0.25-second pulse, followed by 3.3V, another 0.25-second pulse, and a 1.5-second interval.
Rescue Mode
The Z-Uno Module can operate in "Rescue Mode" with User Code disabled. This mode is useful if the User Code is hanging or stuck in an infinite loop. In Rescue Mode, the Z-Uno can be excluded from the Z-Wave network.
To enter Rescue Mode, pull pin 23 (Service Button pin) to ground and simultaneously pull the reset pin (RST_N) to ground, then release it. In rescue mode, the Z-Uno can be re-programmed, added to, or removed from the network. The module will return to its normal state after a power cycle or reset.

Layout and Antenna
Pads Layout
The following layout is recommended for automatic SMD mounting. The gray circle depicts the hole for wire antenna through-hole mounting and can be omitted.
Diagram Description: A diagram shows the recommended PCB layout for automatic SMD mounting, including dimensions and pin arrangements. A gray circle indicates a hole for wire antenna through-hole mounting.
Antenna
The Z-Uno Module requires an antenna to be connected. A SAW filter is already included in the module, depending on the Part No. It is recommended not to place any wires on the host PCB in the area under the Z-Uno antenna matching region (do not fill with ground).
There are three possible options for the antenna:
- 81-86 mm wire antenna.
- 50 Ohm pin.
- 50 Ohm u.fl connector (not soldered).
Do not connect more than one antenna to the Z-Uno Module.
Wire antenna length should be measured from the Z-Uno Module PCB top level. For flexibility, it is recommended not to solder the wire on the antenna side; instead, solder on the bottom of both the Z-Uno and host PCB. A hole in the host PCB, as shown by the gray circle on the pads layout, is required in this case.
For non-flexible wire antennas, soldering can be done on the top side, and the hole in the host PCB is not needed.
If the 50 Ohm RF pin is not used (u.fl or wire is used), leave this pin non-connected. If used, ensure the PCB thickness and surrounding ground pins are considered for the PCB RF path and PCB antenna design.
| Antenna length (L) | Frequency |
|---|---|
| 86 mm (868 MHz) | EU/RU/IN/CN frequencies |
| 82 mm (914 MHz) | US/IL frequencies |
| 81 mm (923 MHz) | ANZ/BR/JP/TW frequencies |
Diagram Description: A diagram illustrates flexible wire antenna soldering recommendations, showing the Z-Uno PCB, Host PCB, and solder connection, with an isolation area for the wire.
