NORVI X Modular Controller
Configure the right NORVI X for your application
Choose the CPU, memory variant and expansion modules. The configurator checks module count, I/O total, DIN rail width and documented compatibility rules as you build.
Build your configuration
Start with the network available at the installation, then add only the expansion I/O you need.
1. Choose CPUCPU selection is mainly based on required connectivity.
2. Choose memoryStandard N16R2 supports all listed expansion modules.
3. Add expansion modulesUse the controls below to create the required I/O mix.
Compare NORVI X CPUs
The core ESP32-S3 controller platform is shared. Cellular hardware is the main model-selection difference.

Expansion resource guide
Modules can be mixed across different address groups. Limits apply within each I²C family, while X-DI4, X-Q4 and X-UARTIO use fixed GPIO resources.

X-DI4X-Q4X-UARTIO
X-DI4 and X-UARTIO conflict because both use IO5, IO6, IO7 and IO10.
Direct GPIO combinations
| Combination | Supported | Reason |
|---|---|---|
| X-DI4 + X-UARTIO | No | Both use IO5, IO6, IO7 and IO10. |
| X-DI4 + X-Q4 | Yes | They use different expansion I/O groups. |
| X-Q4 + X-UARTIO | Yes | They use different expansion I/O groups. |
| X-DI4 + X-Q4 + X-UARTIO | No | X-DI4 and X-UARTIO still conflict. |
