Sera NX040 Series - UWB + Bluetooth LE + NFC Modules
Overview
The time has come for Ultra-Wide Band (UWB) to grow beyond the consumer and automotive segments into mainstream IoT devices. Our innovative integration of the best wireless silicon from NXP and Nordic Semiconductor has produced the secure, flexible Sera NX040 range.
The series features tightly integrated hardware and RF designs, all optimized for low power operation and reducing the need for external clocks, filters and components. Already using Bluetooth LE for basic beaconing or RSSI-based ranging? Now, easily advance to the next level with NFC and UWB for more granular locationing and positioning. This granularity yields much higher accuracy compared to RSSI-only proximity applications in industrial environments.
The Sera NX040 series provides added value hardware and software capabilities to accelerate your development of UWB/BLE applications:
- Rapid firmware app development in Python with on-module scripting engine, OR work directly with nRF Connect SDK
- Ranging toolkit: visualization and sample applications available
- Built on Zephyr RTOS for extensibility
- Tag-to-tag and tag-as-anchor applications for fast evaluation
- Mobile app for easy configuration and view of real-time tag status
- AT Command set for hosted designs, with host-side libraries

Certified Antennas
What is Fira and do I need to be a member to use UWB?
fira is the industry consortium that defines the UWB ranging specification and certifies products for the purposes of interoperability. The name stands for "fine ranging".
There are various levels of fira membership as listed at the link below
Laird Connectivity is an adopter member of fira.
fira membership is required to access specifications (fira intellectual property) and to certify end products.
What is Laird Connectivity's product lifecycle EOL and PCN policy?
Laird Connectivity is committed to the long-term supply of all its standard embedded wireless modules and packaged products. Laird Connectivity’s products are specifically designed to meet the needs of the industrial and medical markets, which typically require 7 – 10 years product lifecycle. Although Laird Connectivity can’t guarantee that a component used in our products will not be obsoleted and cannot be reasonably substituted, Laird Connectivity can assure customers we will continue to sell our product when we have customer demand and can obtain the necessary components to build our products.
