Renesas RA6W1/RA6W2 Cortex-M33 wireless MCUs offer dual-band Wi-Fi 6, BLE, Matter, 15-year availability

Renesas has added the RA6W1 (Wi-Fi 6) and the RA6W2 (Wi-Fi 6 + BLE) MCUs to its high-performance RA6 family, adding dual-band Wi-Fi 6 and Bluetooth LE, as well as Matter connectivity to the series. Both models feature a 160 MHz Arm Cortex-M33 core, dual-band Wi-Fi 6 with WPA3 security, on-chip PA/LNA/RF switch, and a full TCP/IP stack for fast connectivity. They integrate up to 704 KB SRAM, 256 KB ROM, and support eMMC/SD, O-QSPI, and QSPI for external flash and/or PSRAM. The series also includes generic peripherals like SPI, I²C, I²S/PDM, SDIO, 12-bit ADCs, PWM timers, and up to 28 GPIOs. Offered in compact QFN/WLCSP packages, the RA6W1/2 MCUs target smart home, wearables, industrial, and consumer IoT markets where long battery life and wireless connectivity are essential. Renesas RA6W1 specifications: MCU core – Arm Cortex-M33 @ up to 160 MHz, Armv8-M architecture with MPU and SysTick Memory & Storage

Robots humanoïdes : PoC wormable chez Unitree et risque de « botnets sur pattes »

Selon The Register (interview publiée le 9 déc. 2025), Joseph Rooke, directeur Risk Insights chez Recorded Future (Insikt Group), met en garde contre une « tempête parfaite » de risques cyber liée à la convergence robotique + IA + besoin sociétal, avec la perspective de « botnets en forme physique » alors que des humanoïdes s’industrialisent (Unitree, Agility, Engineered Arts, BMW, Toyota, Tesla, Hyundai/Boston Dynamics). Des chercheurs (Víctor Mayoral-Vilches, Andreas Makris, Kevin Finisterre) ont publié fin septembre un proof-of-concept détaillant plusieurs vulnérabilités dans l’interface de configuration BLE Wi‑Fi des robots Unitree : clés cryptographiques en dur, contournement d’authentification trivial, injection de commandes non assainies. Le tout est décrit comme « complètement wormable » — des robots compromis peuvent en infecter d’autres à portée BLE — permettant une prise de contrôle totale du dispositif. 🤖⚠️

ESP32-C6-Devkit-Lipo – A small, open-source hardware ESP32-C6 board with battery support, UEXT connector

Olimex ESP32-C6-DevKit-Lipo board is a small open-source hardware board based on the ESP32-C6 WiFi 6, Bluetooth 5.0 LE, and Zigbee/Thread SoC with support for LiPo batteries and UEXT expansion modules. It's the second announcement from the company this week, and comes after they introduced the MOD-ESP32-C5 to add wireless connectivity to boards equipped with a UEXT connector. The ESP32-C6-DevKit-Lipo adds to the list of small ESP32-C6 USB-C boards, such as the 01Space ESP32-C6 board and Seeed Studio XIAO ESP32C6, among many others. It's actually larger than most similar boards, but differentiates itself with its open-hardware design, dual USB-C design, breadboard compatibility, LiPo battery circuitry, and a UEXT connector. ESP32-C6-Devkit-Lipo specifications: Wireless module – ESP32-C6-WROOM-1-N4 module Espressif Systems ESP32-C6 SoC CPU - Single-core 32-bit RISC-V processor @ 160 MHz Memory - 512KB SRAM, 16KB low-power SRAM Wireless 2.4 GHz WiFi 6 1T1R with Target Wake Time (TWT) support Bluetooth LE 5.0
