swSIM is an open-source, all-software SIM card simulator that requires no physical SIM hardware. It connects to a PC via PC/SC using the swICC PC/SC reader and can interface with any phone that has a SIM card slot. The project is built with make and gcc, has no extra runtime dependencies, and can be used to interact with a virtual SIM card as if it were a real hardware card.

Bảng phát triển RP2350B Bells&Whistles tích hợp sẵn bộ gỡ lỗi RP2040 (Picoprobe), cổng HDMI (qua PicoDVI), khe cắm thẻ microSD, PSRAM 8MB tùy chọn, flash SPI 4MB, 46 chân GPIO và hai cổng USB-C. Bo mạch hỗ trợ nguồn mở (KiCad, sơ đồ trên GitHub) với giá 29,95 USD trên Tindie.
Lập trình viên muốn phát triển ứng dụng trên RP2040 nhưng gặp khó khăn với việc debug và mở rộng hệ thống cần tìm hiểu cách tích hợp RP2350B để tiết kiệm chi phí và tăng hiệu năng với các tính năng như debug built-in, HDMI, và lưu trữ MicroSD.

A weekly roundup from Embedded covering three main themes: the EU Cyber Resilience Act's first hard deadline arriving September 11, 2026 and its implications for manufacturers; the future of embedded engineering as system complexity outpaces traditional workflows; and partnerships announced at PCIM Europe to accelerate SiC and GaN wide-bandgap semiconductor adoption. Additional product highlights include a certified secure mobile chip, a hybrid IoT module combining satellite/LTE-M/GNSS, a GaN-based solar microinverter reference design, and a 4D area scanner for industrial inspection.
A maker built a handheld slabtop terminal around the Waveshare ESP32-S3-RLCD-4.2, a board pairing an ESP32-S3 microcontroller with a reflective LCD. To power it, they created Solar OS — a custom operating system built on FreeRTOS that compiles all apps into a single binary. The device features a 3D-printed case, mini keyboard, and battery. Solar OS supports Python and Lua scripting with hardware API access, and ships with a file manager, web browser, chat client, MP3 player, image viewer, text editor, and games. The creator is seeking community input on evolving the form factor toward a palmtop design.
ESP-GenUI is a browser-based GUI tool for building web interfaces on the ESP32 microcontroller. It uses a node-based drag-and-drop canvas to create dashboards and control panels with elements like GPIO controls, camera feeds, and gauges. The generated code can be flashed directly from the browser or exported as Arduino code for use in the IDE.
Makerfabs has released the MaTouch ESP32-P4 TFTTouch 10.1, a development board combining the ESP32-P4 and ESP32-C6 chips with a 10.1-inch 1280×800 IPS touchscreen display. Key differentiators from similar boards include a SIMCom SIM7670G 4G LTE Cat 1 modem with SIM slot, RJ45 Ethernet, and a 2MP MIPI camera. The board also includes WiFi 6, Bluetooth 5, Zigbee/Thread/Matter via the ESP32-C6, audio I/O, microSD, five USB-C ports, and GPIO expansion headers. Software support covers ESP-IDF, Arduino IDE, PlatformIO, and LVGL. It is priced at $79.80 and ships with a 32GB microSD card in a basic enclosure.
Sonocotta's Louder ESP32 Mini is a compact open-source hardware board designed to retrofit old passive speakers with WiFi and Bluetooth connectivity. Built around the ESP32-S3 with 8MB PSRAM and a TAS5805M DAC/amplifier, it comes in two sizes (42×42mm and 52×52mm) and replaces the standard speaker terminal cup. It supports multiple firmware options including Squeezelite-ESP32 for Spotify Connect and AirPlay, Snapclient for multi-room audio, and ESPHome for Home Assistant integration. Priced at $15–$20, it's available on Lectronz and Tindie, with schematics and Gerber files published on GitHub.
Orange Pi 6 is a new compact SBC (90x90mm) powered by the CIX P1 (CD8180) 12-core Arm Cortex-A720/A520 SoC with up to 32GB LPDDR5 RAM. Compared to the larger Orange Pi 6 Plus, it features 2.5GbE instead of 5GbE networking, drops LiPo battery support, and comes in a smaller form factor. Key specs include dual M.2 PCIe Gen4 x4 slots, multiple display outputs, a 28.85 TOPS NPU, and support for Debian, Ubuntu, Android, Windows 11, and OpenHarmony. Pricing starts at $239 for the 8GB model, reflecting the high cost of LPDDR5 RAM, making it significantly pricier than typical Orange Pi boards.
OpenC6 BIOS is an open-source project that brings PC BIOS-like architecture to the ESP32-C6 microcontroller. Instead of combining hardware setup and application code into a single firmware image, it separates the base system from application payloads (2–10 KB). Key features include dynamic CPU frequency scaling, a System Call Interface (ABI) for Wi-Fi/crypto/math access without full ESP-IDF, PXE-like network boot over Wi-Fi, A/B OTA updates with rollback, a web-based BIOS setup interface, LP-Core health monitoring using the ESP32-C6's low-power RISC-V core, and Aura Sync RGB support. The project targets ESP32-C6 boards with at least 8MB flash and is available on GitHub under the MIT license.
