Cytron's cheaper Raspberry Pi 4 boards are a solid deal if you can live with 30% less speed

RP2350B bells&whistles development board features on-board RP2040 debugger, HDMI, and microSD card slot

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.

Discounted 1.25 GHz Raspberry Pi 4 Model B shows up online

Cytron bán Raspberry Pi 4 Model B "Special Value Board" với RAM 4GB/8GB, xung nhịp 1.25 GHz (thấp hơn chuẩn 1.8 GHz) do lỗi sản xuất nhưng vẫn hoạt động ổn định. Giá giảm còn $87.25 (4GB) và $147 (8GB), tiết kiệm $13–$18, nhưng chỉ còn 258/189 sản phẩm.

Lập trình viên nên đọc vì những phiên bản Raspberry Pi 4 này có giá thấp hơn đáng kể nhưng vẫn hoạt động ổn định, giúp bạn có thể thử nghiệm các ứng dụng hoặc dự án với chi phí tiết kiệm mà không lo về hiệu suất bị giảm đáng kể.

Review: Gamrombo PS5 controller - including Linux set up

A hands-on review of the Gamrombo PS5 controller, a ~£40 third-party alternative to the official DualSense. It works out of the box on Linux via USB-C and Bluetooth, registers as a Sony DualSense, and supports touchpad gestures, vibration, speaker, and 3.5mm audio. Extras include programmable macro buttons and a turbo function. Downsides include no microphone, Windows-only firmware updater distributed via WeTransfer, no charging dock support, and a slightly cheaper feel compared to the official controller.

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.

The CPU's growing role in agentic AI infrastructure

Arm-sponsored content arguing that CPUs play a critical but underappreciated role in agentic AI infrastructure. While accelerators handle model performance, CPUs act as the control plane — managing data movement, workload scheduling, and secure isolation. Arm's Neoverse platform underpins custom silicon from AWS (Graviton), Google (Axion), Microsoft (Azure Cobalt), and NVIDIA (Grace Hopper/Blackwell), all reflecting a shift toward purpose-built Arm-based processors in cloud and AI datacenters. The piece introduces the Arm AGI CPU, built with Meta, targeting rack-level density for agentic AI deployments.

This Raspberry Pi price tracker is shutting down next month because retailers blocked its bot

RPI Locator, a popular Raspberry Pi price tracking site, is shutting down in July after retailers began blocking its web scraping bots. The site's owner tried various workarounds but none lasted more than a few days or weeks. With Raspberry Pi prices having risen significantly, the closure makes finding good deals harder for hobbyists.
