M5MonsterC5 hacking tool adds ESP32-C5 and 5 GHz Wi-Fi 6 support to M5Stack Cardputer ADV and Tab5

Developed by Laboratorium in Poland, the M5MonsterC5 is an ESP32-C5-based “Marauder” hacking tool designed to work with M5Stack Cardputer ADV or M5Stack Tab5. It gets connected to the Cardputer ADV or Tab5 via a Grove connector and runs JanOS and Project Zero for wireless security research, experimentation, and rapid prototyping with minimal setup. Built around the ESP32-C5, the device supports dual-band Wi-Fi 6 (2.4/5-GHz) and 802.15.4 (Thread/Zigbee) to the M5Stack devices. Key features include multi-channel deauthentication with 5 GHz support, Evil Twin and phishing captive portals, WPA3 SAE overflow attacks, wardriving with GPS logging and WiGLE-compatible exports, passive sniffing, Karma attacks, whitelist management, and persistent “blackout” modes. The platform uses a two-stage web-based flashing process (JanOS on the Monster board and a Cardputer app flasher), offers microSD card and optional GPS support, and is intended strictly for authorized Wi-Fi auditing, offensive security research, and educational use under the Project Zero […]

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 […]
