Laird Connectivity has announcd that ultra-wideband (UWB) technology will soon join the Laird Connectivity portfolio. The upcoming Sere NXo40 module series combines UWB and Bluetooth Low Energy (LE) into one solution that Laird claims delivers precise, granular positioning and processing for medical and industrial IoT applications.

This UWB tag solution integrates the  Trimension SR040 chipset UWB silicon from NXP with the processing and Bluetooth LE capabilities of Nordic Semiconductor’s nRF52833 system-on-chip (SoC). This combination, says Laird, paired with its added value hardware, software, and services, brings new possibilities for UWB to grow beyond consumer and automotive segments into mainstream IoT devices.


Key features include:
NXP Trimension™ SR040 – IEEE 802.15.4z UWB silicon​
·   Nordic Semiconductor nRF52833 – Bluetooth LE, NFC and MCU
.  ARM Cortex M4 (64 MHz) – 512kB / 128kB
·   Small form factor PCB modules with multiple antenna options
·   Seamless multiprotocol integration
.  Bluetooth LE 5.4 and NFC
.  UWB – channels 5 and 9
·   Flexible I/O – GPIO, UART, I2C, SPI, USB
·   All required external components, crystals, filters and
additional 8Mbit Flash
·   Ultra-low power consumption with coin cell operation
·   Industrial temperature range -40 °C to +85 °C ​
·   Regulatory – FCC, ISED, CE, UKCA, MIC, RCM (pending)​
.  Bluetooth SIG and FiRa Consortium (pending)
