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 […]

LILYGO T-Beam 1W – An ESP32-S3 + SX1262 high-power LoRa dev board with 32 dBm output, GNSS support

The LILYGO T-Beam-1W is an ESP32-S3-based high-power LoRa development board featuring an SX1262 RF transceiver, an onboard 1W power amplifier (32 dBm), a L76K GNSS module, a 1.3-inch SH1106 OLED, a microSD slot, USB-C, Qwiic connectors, and an AXP2101 PMU. The board runs on a 7.4V battery and includes a cooling fan for high-power RF operation. We first wrote about the original LILYGO T-Beam (then branded as TTGO) in 2018, and since then, the company introduced various revisions of the T-Beam as it became popular. The T-Beam 1W is the most powerful version so far, with a built-in 1 Watt amplifier that allows the board to transmit data over longer distances without needing to buy separate, bulky amplifiers.

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 […]

Year 2025 in Review, CNX Software stats, and looking ahead to 2026

Time for the last post of 2025, as the year is almost over. I’ll look back at key developments and notable products launched in 2025, share some CNX Software website traffic statistics, and look ahead to 2026. Year 2025 in Review After 22 product releases in 2024, Raspberry Pi calmed down a little bit in 2025, and the highlights of the year included the Raspberry Pi 500+ mechanical keyboard, the 5-inch variant of the Raspberry Pi Touch Display 2, and a Raspberry Pi 5 1GB RAM. What didn’t quite stop were the accessories from third parties for Raspberry Pi SBC and Raspberry Pi Pico boards. The most exciting Arm SoC release of 2025 was probably the 12-core CIX P1 Armv9 SoC found in Radxa Orion O6 SBC, MINISFORUM MS-R1 Arm mini PC, and Orange Pi 6 Plus board, but while performance was fine, it was overhyped in 2024, and software […]
