Ezurio Sona NX611 - An NXP IW611-powered Wi-Fi 6 industrial IoT module

Ezurio, formerly Laird Connectivity, has announced the Sona NX611, a new Wi-Fi 6 module designed for industrial IoT applications. The module uses the NXP IW611 chipset and supports Wi-Fi 6 (802.11ax) and Bluetooth 5.4. It operates in the 2.4 GHz and 5 GHz bands, achieving data rates up to 600 Mbps, and can withstand industrial temperatures from -40°C to +85°C.

The Sona NX611 comes in several form factors, including SiP (System-in-Package), M.2 1216 SMT, and M.2 2230 E-Key pluggable options. It is compatible with NXP processors and supports Ezurio’s Linux connectivity stack software and Android OS. The module is under development and is expected to be in mass production by September 2024. It will have global certifications like FCC, ISED, UKCA, CE, and Bluetooth SIG.

Previously we have seen the IW611 and IW612 modules were used in the u-blox MAYA-W2 IoT module. We have also written about Laird RM126x LoRaWAN modules, Tungsten700 SMARC SoM, and devkit, which are also developed by Ezurio, formerly Laird Connectivity.
