Renesas RL78/L23 16-bit MCU features segment LCD interface, SMS for low-power HMI systems
Renesas’ RL78/L23 is a low-power 16-bit MCU with built-in segment LCD, capacitive touch, dual-bank flash for FOTA, and a wide 1.6–5.5 V operating voltage range. It targets HMI appliances, metering, and low-cost IoT products with support up to 2037. Key features include up to 512 KB dual-bank flash, 32 KB SRAM, 8 KB data flash, with ~1 µs wake-up, and SMS (Snooze Mode Sequencer) to run LCD/touch tasks without waking the CPU. It integrates a segment LCD controller with a new VL4 reference mode that cuts LCD current by ~30% compared to the RL78/L1x. Connectivity and sensing options include UART/I²C/CSI,...

Quectel KCMCA6S industrial wM-bus modules target smart metering
Quectel’s KCMCA6S is a series of industrial wireless M-Bus (wM-Bus) modules built around Silicon Labs’ EFR32FG23 chipset. The modules operate in the 868 MHz, 169 MHz, and 433 MHz bands and support the EN13757-4 wM-Bus standard for smart metering and AMI (Advanced Metering Infrastructure) applications. The device features an Arm Cortex-M33 processor, 32 KB of SRAM, 256 KB of flash, and a Sub-GHz transceiver. It supports multiple wM-Bus modes (T, C, S, R, N, F), with dynamic multi-mode switching, flexible frequency configuration, and low-power operation alongside multi-layer security mechanisms. Interfaces include USART, SWD, and GPIOs, with optional EUSART, I²C, and...
Arm introduces Lumex platform with SME2-enabled C1 CPU for Edge AI, Mali-G1 GPU
Arm Lumex CSS (Compute SubSystem) platform for mobile devices combines high-performance Arm C1 CPUs with Scalable Matrix Extension version 2 (SME2) and Mali-G1 GPUs to enable real-time on-device AI use cases like assistants, voice translation, and personalization. Lumex is part of Arm’s new product naming architecture announced last May, and targets specifically mobile devices. Arm says SME2-enabled Arm CPUs can deliver up to 5x faster AI performance, 4.7x lower latency for speech-based workloads, and 2.8x faster audio generation. Lumex components: Next-generation SME2-enabled Armv9.3 CPU cluster: C1-Ultra for flagship peak performance with +25% single-thread performance vs Cortex-X925; suitable for large-model inference,...
SpecFive Strike Handheld Linux Workstation with LoRa Mesh
The SpecFive Strike is a handheld Linux workstation with integrated LoRa mesh networking. Built on the Raspberry Pi Compute Module 4 and a custom SpecFive carrier board, it targets developers, makers, hackers, and off-grid communicators by combining Linux computing, wireless connectivity, and portability. The device comes in a PETG enclosure featuring a 4.3-inch touchscreen and […]
Baguette S3 ESP32-S3 board gets the breadboard-friendly crown
We often write about breadboard-friendly boards, which typically means they plug nicely into a breadboard, but usually leave only one or two rows to play with on each side. So far, the best option we have come across is probably the Raspberry Breadstick, which is designed for full-length breadboards, but is limited by the I/Os on the Raspberry Pi RP2040 MCU. When it comes to breadboard friendliness, it’s hard to beat The Pi Hut’s Baguette S3, as it provides a single 30-pin header designed to be inserted in one of the rows of a breadboard, leaving plenty of space for...
Hackabone Project Offers BeagleBone-Based Embedded Linux Training with Emulated Framework
A new initiative called Hackabone has been launched with the goal of providing more accessible Embedded Linux training. Created by long-time Embedded and real-time Linux instructor Alejandro Lucero, the project combines detailed documentation with a web-based emulation framework centered around the BeagleBone Black single-board computer. The project name, short for “Hack-a-Bone,” reflects its emphasis on […]
Retro Computer Repair party on September 17th at Olimex!
The Meshtastic event on September 3rd went great. More than 30 people gathered, some of them traveling from other cities especially for it. Dimitar Gamishev presented what Meshtastic is, compared it with LoRaWAN, and showed how he implemented it with the ESP32-POE and MOD-LoRa868-ANT. After him, Todor Kandev (LZ5AE) demonstrated various devices he has worked […]

QMK-compatible macro keyboard features 0.85-inch LCD keycaps, 2.01-inch display
Waveshare has recently released the MK10, a Stream Deck-like macro keyboard featuring ten mechanical keys with 0.85-inch LCD keycaps and a secondary 2.01-inch screen. The macro keyboard also supports AI voice interaction, real-time hardware and weather data integration, and customizable themes with drag-and-drop editing. The company also highlights Home Assistant compatibility for Smart Home control. The device features a dual-system architecture, where an Allwinner T113-S3 dual-core Cortex-A7 processor runs Linux, and a GD32 microcontroller runs QMK firmware, ensuring low-latency mechanical input. The 10 LCD keys can display images or videos with overlay support, and the 2.01-inch screen shows additional status...
Axelera Metis M.2 Max Edge AI module doubles LLM and VLM processing speed
Axelera AI’s Metis M.2 Max is an M.2 module based on an upgraded Metis AI processor unit (AIPU) delivering twice the memory bandwidth of the current Metis M.2 module for compute-intensive Edge AI inference applications such as large language models (LLMs) and vision language models (VLMs).
