Quectel SRG091X and SRG093X NXP i.MX 9 industrial AIoT modules integrates Wi-Fi 6, Bluetooth 5.4, and 802.15.4 radios

Quectel SRG091X and SRG093X NXP i.MX Smart AIoT module

After releasing the very powerful P895BD-AP AIoT module at CES 2026, Quectel now released two new low-power industrial AIoT modules based on NXP’s i.MX 9 series SoCs. The module integrates Wi-Fi 6, Bluetooth 5.4, and 802.15.4 radios through the IW610G chipset, so it can simply be dropped into a PCB to create a fully compliant Matter Border Router without any RF design or coexistence concerns. While both modules share the same 46 x 41.5 mm form factor and wireless capabilities, they are different in terms of CPU power as the SRG091X is an entry-level solution built around a single-core NXP i.MX 91 processor, while the SRG093X features dual-core NXP i.MX 93 SoC, which includes a Cortex-M33 real-time core and a neural processing unit (NPU) for edge AI workloads. The module supports LPDDR4/LPDDR4X memory, eMMC storage, and various I/O options, including dual Gigabit Ethernet, USB 2.0, CAN-FD, SPI, UART, I²C/I³C, ADC, […]

Nordic Semi nRF54LM20B wireless SoC integrates 128 MHz Axon NPU for Edge AI workloads

Nordic Semi nRF54ML20B Arm Cortex-M33 wireless SoC is the first nRF54L microcontroller to integrate the ultra-efficient Axon Neural Processing Unit (NPU) for edge AI workloads. The NPU is said to deliver up to 7 times faster performance and up to 8 times higher energy efficiency versus (unnamed) competing wireless solutions for tasks such as sound classification, keyword spotting, and image-based detection. The Axon NPU is also about 15x faster compared to using the Cortex-M33 CPU for the same task. Other than the NPU, the nRF54LM20B offers exactly the same features as the earlier nRF54LM20A wireless microcontroller, including up to 2 MB NVM, 512 KB RAM, a 128 MHz Arm Cortex-M33 plus RISC-V coprocessor, high-speed USB, up to 66 GPIOs, and an ultra-low-power 2.4 GHz radio supporting Bluetooth LE, Bluetooth Channel Sounding, Matter over Thread, and more as shown in the nRF54L comparison table below. Like other nRF54L wireless SoCs, the […]
