The MCX A series has just been launched, and the high-end MCX N also has its own product page with the N94x and N54x variants. We’ll focus on […]

FOSDEM 2024 schedule – Open-source embedded, mobile, IoT, robotics, RISC-V, etc..


FOSDEM – which stands for Free and Open Source Software Developers’ European Meeting – is a free-to-participate event where thousands of developers meet in Brussels on the first week-end of February to discuss open-source software & hardware projects. FOSDEM 2024 will take place on February 3-4 with 880 speakers, 818 events, and 66 tracks. Although I won’t attend, I’ve created a virtual schedule like every year with sessions most relevant to the topics covered on CNX Software from the “Embedded, Mobile and Automotive” and “Open Hardware and CAD/CAM” devrooms, but also other devrooms including “FOSS Mobile Devices”, “ Energy: Reimagining this Ecosystem through Open Source”, “RISC-V”, and others. FOSDEM Day 1 – Saturday, February 3, 2024 10:30 – 10:55 – Screen Sharing on Raspberry Pi 5 Using VNC in Weston and Wayland with the Yocto Project and OpenEmbedded by Leon Anavi In 2023, embedded Linux developers received eagerly awaited news: […]

STMicro STM32WL3 sub-GHz wireless MCU targets smart metering, smart building, and industrial monitoring


STMicroelectronics STM32WL3 is an Arm Cortex-M0+ low-power, long-range, multi-protocol wireless microcontroller working in sub-GHz ISM frequency bands, namely 413MHz – 479MHz, 826MHz – 958MHz, and soon 169MHz (2024) for protocols such as wireless M-Bus (mode N) and Wize. The multi-protocol and multi-modulation radio supports 4-(G)FSK up to 600kbit/s, 2-(G)FSK, (G)MSK, DBPSK, DSSS, OOK, ASK modulation schemes suitable for proprietary and standardized wireless protocols such as Sigfox, KNX, WiSun, mioty, M-Bus, and others.

NEWRACOM NRC7394 WiFi HaLow SoC delivers higher power efficiency and cost-effectiveness

Low cost WiFi Halow SoC

NEWRACOM has just introduced the NRC7394 Wi-Fi HaLow Arm Cortex-M3 SoC with higher power efficiency and lower cost than the previous generation NRC7292 Cortex-M3/M0 HaLow SoC and available in a 6x6mm package. I first wrote about the 802.11ah standard in 2014. Also known as the WiFi HaLow (consumers name), it operates in the 900 MHz band, offers a longer range and lower power consumption for items like IP cameras, and the first products came to market in 2021. I was expecting a flood of new WiFi HaLow devices in 2022 in my year 2021 round-up and it was not exactly a prescient prediction as it never happened. But maybe the new NRC7394 SoC will help make WiFi HaLow devices more popular by lowering the costs and further improving battery life. NEWRACOM NRC7394 key features: CPU – Arm Cortex-M3 core @ 32 MHz for IEEE 802.11ah WLAN and application Connectivity Full […]

ST87M01 NB-IoT & GNSS module targets global cellular IoT deployments, asset tracking applications

STMicro ST87M01 NB-IoT module

STMicro ST87M01 is a compact, low-power, programmable LTE Cat NB2 (NB-IoT) industrial cellular module with GNSS geo-location capability for “massive IoT” deployments and asset tracking applications. STMicro already had several LPWAN solutions such as the STM32WL LoRa SoC, a Wi-SUN transceiver, a few SigFox chips, and a bunch of proprietary sub-GHz chips, but no cellular IoT solutions of their own although the STM32 microcontroller can be found in many third-party solutions. The ST87M01 NB-IoT and GNSS module changes that, so let’s have a closer look. ST87M01 NB-IoT module specifications: Cellular LTE, Category NB2, Release 15 Worldwide regional bands coverage Single-tone / Multi-tone / Extended TBS and 2 HARQ Up to DL: 127 kbps, UL: 159 kbps eDRX and PSM support Up to +23 dBm power output Optional ST4SIM embedded SIM (eSIM) GSMA compliant with an additional Secure Element GNSS capability Expansion – Multiple I/F and GPIO Host communication – standardized […]

Wi-SUN: An LPWAN standard for Smart Cities, Smart Agriculture, large scale IoT deployments

Wi SUN network architecture

Wi-SUN is a standard (IEEE 802.15.4g) managed by the Wi-SUN Alliance and designed for Smart Cities, Smart Agriculture, and other large scale IoT deployments with a large number of devices thanks to the use of IPv6 mesh networking. The organization was founded in 2011 to “support the worldwide development of Wireless Communications Networks for Utilities, Smart Cities and IoT”, but due to the niche nature of target applications, it does not get that much press coverage and was only recently brought to my attention. Wi-SUN stands for “Wireless Smart Utility Networks”or “Wireless Smart Ubiquitous Networks”, and the standard aims to connect streetlights, cameras, weather stations, smart metering, utility transmission systems, and others to enable data-sharing between city services to improve their efficiency, save costs, and offer improves services to citizens. Wi-SUN FAN (Field Area Network) is the latest protocol managed by the Wi-SUN Alliance with over 95 million units shipped […]
