FOSDEM 2026 will take place on January 31-February 1, with thousands of developers meeting in Brussels to discuss open-source software & hardware projects. The free-to-attend “Free and Open Source Software Developers’ European Meeting” gets more traction every year, and in 2026, there will be at least 1,113 speakers, 1,016 events, 70 tracks, and potentially close to 10,000 attendees. As usual, I’ll create a virtual schedule 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 “RISC-V”, “Robotics and simulation”, and “FOSS on Mobile”, among others. I’m aware some of the talks overlap by a couple of minutes or so… FOSDEM 2026 Day 1 – Saturday, January 31 10:40 – 11:15 – RISC-V Vector optimisations in FFmpeg by Rémi Denis-Courmont FFmpeg is the most versatile multimedia codec and format support library, and was […]
YumiAI: An AI-Native End-to-End Hardware Innovation Platform For Embedded Engineers (Sponsored)
Anyone who has designed a custom ESP32 board or an RK3588 carrier knows the real bottleneck isn’t creativity — it’s the grunt work. Finding components that are actually in stock, checking pin compatibility, verifying footprints, building symbols, and dealing with yet another “NRND” surprise. It slows down even simple projects. A Multi-Agent System Built for Hardware Workflows YumiAI is an AI-Native Generative Hardware Innovation Platform. YumiAI has five specialized agent clusters: Market Insight agent clusters: General AI gives summaries. YumiAI focuses on “Engineering Feasibility.” It asks: Will we hit patent issues? Is the cost competitive? It outputs a technical research report for hardware decisions. Function Definition agent clusters: interprets requirements (“STM32WL LoRaWAN node, USB-C power”) and structures them into a proper engineering spec. Component Selection agent clusters: pulls real-time availability and pricing from DigiKey, Mouser, and LCSC. Circuit Topology agent clusters: Our Agent has industrial algorithms and simulation built in. It performs “Physical […]

Ridiculously tiny ESP32-C3 board features USB-C, one LED, and a ceramic antenna
PegorK’s f32 might be the world’s smallest ESP32-C3 board. It measures just 9.85 x 8.45 mm, or slightly larger than the area covered by a USB Type-C connector. A board of this size will have limited features, and besides the ESP32-C3FH4 RISC-V WiFi and Bluetooth microcontroller, it comes with a USB-C port, a ceramic antenna, and a single GPIO pin connected to an LED. f32 specifications: SoC – Espressif Systems ESP32-C3FH4 Single-core 32-bit RISC-V microcontroller @ up to 160 MHz Memory – 400 KB SRAM Storage – 4MB flash Wireless 2.4 GHz Wi-Fi 4 & Bluetooth 5.0 USB – 1x USB Type-C port for power and programming Misc Tiny LED connected to GPIO10 Ceramic antenna Crystal Power Supply – 5V via USB-C port; 3.3V LDO Dimensions – 9.85 x 8.45 mm (the height must be around 4-5 mm) The PCB was designed using DipTrace and manufactured with a board thickness […]

ALLPCB offers one dollar PCB prototyping with free shipping (Sponsored)
For hobbyists, small businesses, and engineers in Europe and the United States, prototyping printed circuit boards (PCBs) is a critical step in turning innovative ideas into reality. However, one significant barrier often stands in the way: high shipping costs. These expenses can quickly inflate the total cost of small-scale PCB orders, making prototyping less accessible for individuals and startups with limited budgets. Few PCB manufacturers offer significant discounts on small-scale orders, and shipping fees can sometimes rival or even exceed the cost of the PCBs themselves, discouraging experimentation and innovation. To address this issue, ALLPCB, a leading PCB manufacturing and assembly provider, has launched an exciting new campaign designed to make PCB prototyping more affordable for everyone. New users can now enjoy $30 off their first PCB order, plus an additional $30 off shipping costs. What sets this offer apart is its flexibility—there are no limitations on PCB size, number […]
microSD-express Pi Adapter is an ultra-small microSD Express adapter for the Raspberry Pi 5
We’ve just written about Will Whang’s RPI5-SDexpress-Hat board, which adds a microSD Express slot to the Raspberry Pi 5, but it’s not that small, and it’s using the 40-pin GPIO for power, so it’s not convenient if you want to install another Raspberry Pi HAT+. Vassily Petrov’s “microSD-express Pi Adapter” is a much smaller microSD Express adapter on a flexible PCB that plugs directly into the PCIe FFC connector and nothing else, driving power from the PCIe connector only. There’s not much on the PCB itself besides a microSD Express card slot and a Microchip MIC2230 800mA/800mA step-down DC/DC regulator. We’re told speeds of up to 800 MB/s are achievable, limited by the PCIe Gen3 x1 interface on the Pi 5 itself. For reference, the RPI5-SDexpress-Hat was tested at about 600 MB/s for sequential reads and under 200MB/s for sequential writes using a 256GB Samsung microSD Express card. A worry […]
