MicroPythonOS graphical operating system delivers Android-like user experience on microcontrollers

Yesterday, I wrote about Ariel OS RTOS for microcontrollers written in Rust, but there’s another interesting open-source operating system for microcontrollers that will be covered at FOSDEM 2026: MicroPythonOS. While Ariel OS is designed for secure, memory-safe, networked IoT applications on microcontrollers, MicroPythonOS targets applications with graphical user interfaces and is heavily inspired by Android and iOS, with an appstore, an LVGL-based touchscreen and button UI with plenty of widgets, gestures and theme support, and a wifi manager, as well as over-the-air (OTA) firmware updates. You’ll probably be astonished to learn that MicroPythonOS is written in… MicroPython. It’s comprised of a Thin OS which handles hardware initialization, multitasking, and UI, and everything else is an app, including system features like WiFi configuration and OS updates. MicroPythonOS highlights: Native MicroPython foundation Runs on ESP32 microcontrollers, but the FOSDEM 2026 talk mentions that it can run on anything that supports MicroPython, including […]

ACEBOTT QD023 ESP32-based gesture control glove tracks finger movements with potentiometers

ACEBOTT QD023 ESP32 Motion Sensing Glove

ACEBOTT QD023 is an ESP32-based wearable gesture control glove that tracks finger movements with potentiometers instead of more traditional flex sensors. The glove transmits data via Bluetooth Low Energy (BLE) to control various robotics kits, such as bipedal walkers, mecanum-wheeled cars, and robotic arms. The glove integrates five potentiometers for finger bending detection, and a 6-axis MPU6050 IMU for wrist rotation, tilt, and hand posture detection in real time. Other Hardware features include a USB Type-C port for programming and debugging, four AAA batteries for power, buttons, LEDs, and more. Tutorials and assembly guides make it suitable for K-12 education, classrooms, and hobbyist robotics projects. ACEBOTT QD023 specifications: Wireless Module – ESP32-WROOM-32D (soldered on the backside of the PCB) SoC – ESP32 dual-core wireless microcontroller CPU – Dual-core Xtensa 32-bit microprocessor @ 240MHz Memory – 520KB internal SRAM Wireless – Wi-Fi 802.11b/g/n, and Bluetooth (4.2 and BLE) PCB antenna USB – […]

FOSDEM 2026 schedule – Embedded, RISC-V, Robotics, Rust, Open Hardware, and more

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 […]
