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 BIOS For Your ESP32-C6

Rompass đã phát triển một firmware tương tự BIOS cho vi điều khiển ESP32-C6, cung cấp bootloader và lớp API hỗ trợ tải động các chương trình từ RAM, thậm chí qua mạng. Dự án thể hiện xu hướng xóa nhòa ranh giới giữa vi điều khiển và bộ vi xử lý, xu hướng này sẽ tiếp tục khi các bộ xử lý ứng dụng mạnh mẽ như ESP32-P4 trở nên phổ biến.

Lập trình viên ESP32-C6 nên đọc để khám phá cách mở rộng khả năng quản lý khởi động và chạy ứng dụng động từ RAM hoặc mạng, giúp tối ưu hóa hiệu suất và linh hoạt cho các dự án yêu cầu tính linh hoạt cao hơn.

Linux 7.2 Drops Ancient PROFIBUS Driver: Ported From SCO Unix In 1998, Unused For Years

Linux 7.2 is removing two obsolete drivers from its source tree: the DTLK ISA speech synthesizer driver and the Applicom PROFIBUS driver. The Applicom driver was originally ported from SCO Unix in 1998, has had severe coding style issues, was broken for years in early Git history, and has no known active users. Later Applicom hardware only officially supports Windows and has been discontinued. The removals together eliminate approximately 19,500 lines of code, reducing future maintenance burden.

Orange Pi 6 CIX CD8180 12-core Arm SBC gets 2.5GbE networking, smaller form factor, drops battery support

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.

Quectel FCM365X dual-band WiFi 6, BLE 5.4, 802.15.4 IoT module features NXP RW612 MCU, optional PSRAM

Quectel has officially launched the FCM365X, a compact 25.5×18mm IoT module built on the NXP RW612 wireless MCU. It supports dual-band Wi-Fi 6, Bluetooth 5.4 LE, and 802.15.4 (Zigbee, Thread, Matter over Thread), with 8MB SPI flash and optional PSRAM — making it the only RW612-based module currently offering on-module PSRAM. The module exposes a wide range of interfaces (GPIO, UART, USB, I2C, I2S, ADC, LCD, PWM) via LCC+LGA packaging and operates from -40°C to +85°C. Development is SDK-based via QuecOpen; AT command firmware is not available. Two development boards are planned but details and pricing are not yet published.

OpenC6 BIOS project brings PC-like firmware to ESP32-C6 MCU with network boot and OTA update support

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.

Iridium Development Kit Accelerates Hybrid IoT Design

Iridium Communications has launched the 9604 module and development kit, a hybrid IoT platform combining satellite (SBD), LTE-M cellular, and GNSS into a single compact module (16×26×2.4 mm). Built on the u-blox SARA-R5 platform, it can reduce board space by over 60% versus discrete implementations. The module supports GPS, GLONASS, Galileo, and BeiDou, offers independent subsystem management for custom failover strategies, and provides a unified AT command interface with an SDK. It targets industrial monitoring, transportation, maritime, and remote asset tracking applications where terrestrial networks may be unavailable.
