Program freely
Build your application on a full ESP32-S3 using Arduino or ESP-IDF, with no proprietary runtime required for your code.
INTRODUCING NORVI
XN
NORVI XN.
The industrial ESP32 controller that
stays reachable.
Your application runs on an ESP32-S3 you fully control. A separate OTA Manager handles cellular communication, firmware updates and live serial access, helping you diagnose and recover a field unit without visiting the site.

WHY TWO PROCESSORS?
Crashed firmware. Still reachable.
The independent OTA Manager is designed to keep remote diagnostics and firmware updates available even when the application stops responding, provided power and cellular connectivity remain available.
Diagnose and recover remotelyLive serial output + firmware delivery through NORVI Neural.
WHY CHOOSE XN
Focus on your application.
Not the connectivity stack.
Four practical reasons to choose XN for industrial devices deployed outside the development lab.
Separate update control
The independent OTA Manager handles firmware delivery and device access alongside the main application.
Debug from your desk
Read live serial output from a deployed unit and push an updated build without plugging in a USB cable on site.
Less modem code
Keep AT commands, modem state handling and cellular session management out of your application firmware.

Cloud compile and OTA delivery without local setup.
Live logs and remote diagnostics through the OTA Manager.
Neural Studio
Write, build and flash ESP32 firmware from the browser without setting up a local toolchain.
Neural Deploy
Manage firmware rollouts to deployed units with verification, retries and recovery workflows.
Neural Pulse
See live serial output from a deployed unit and troubleshoot from your workstation.
Neural Insight
Publish application values as telemetry and connect to dashboards including Datacake.

FREQUENTLY ASKED QUESTIONS
Questions from engineers.
Answers to the most useful early product questions.
Ask NORVI a technical questionCan I program XN without using NORVI Neural?
Yes. The application processor is a standard ESP32-S3 and supports Arduino and ESP-IDF development. NORVI Neural is an optional companion workflow.
What happens if my application firmware crashes?
The independent OTA Manager is designed to preserve remote serial access and support firmware recovery independently of the main application, as long as the device remains powered and connected.
Which cellular modem or SIM is supplied?
Cellular hardware options include Quectel EC25 and SIMCom A7672. The appropriate module depends on the deployment region. SIM options should be confirmed when registering interest.
Does XN work with existing NORVI X expansion modules?
Yes, NORVI XN uses the NORVI X expansion module family. Check module addressing and direct GPIO compatibility before choosing a configuration.
Can I request an evaluation unit or pilot quantity?
Yes. Select “Evaluation unit” or “Pilot quantity” in the interest form and share your project requirements so the NORVI team can discuss the next steps.
When will NORVI XN ship?
Shipment availability has not been announced here. Register your interest or contact NORVI to confirm current timelines.
