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.

PiZZa turns your spare Raspberry Pi Zero W and 2 W into an Arduino

PiZZa (Pi Zero with Zephyr for Arduino) is a project that converts a Raspberry Pi Zero W or Zero 2 W into an Arduino-compatible board. After a one-time SD card setup, users can write and upload Arduino sketches directly from Arduino IDE 2.x with a single click — no SD swaps or manual reflashing required. It works on Windows, macOS, and Linux, and requires only a Pi Zero W/2W, a microSD card larger than 2GB, and a micro-USB data cable. The project lets makers reuse spare hardware while benefiting from the Pi's faster boot times and extra processing power.

This KVM Runs A P4 Instead Of A Pi.

A developer built an IP KVM using the ESP32-P4 microcontroller instead of the typical Raspberry Pi, achieving 1080p video capture via a commercial HDMI-to-CSI adapter board. The trickiest part was writing a custom driver for the camera input. The project is open source under the Apache license on GitHub, though it currently lacks audio, WiFi support, and any security. The post reflects on the growing trend of using the powerful ESP32-P4 for tasks traditionally handled by Linux SBCs like the Raspberry Pi.

Someone used a Raspberry Pi 5 to give Claude Fable 5 a robot body, because that's not worrying or anything

Một người chơi đã chế tạo robot đi bộ điều khiển bởi Claude Fable 5, sử dụng Raspberry Pi 5 làm bộ não chính và Nvidia Jetson Nano để xử lý thị giác. Robot trang bị hai camera stereo, chạy hệ thống phần cứng và điều khiển cục bộ, đồng thời giao tiếp với mô hình Claude qua API để ra quyết định.

Lập trình viên nên đọc bài này để khám phá cách kết hợp các thiết bị IoT hiện đại—như Raspberry Pi 5 và Jetson Nano—với AI để tạo ra hệ thống tự động hóa phức tạp, từ đó học cách tối ưu hóa kiến trúc phần cứng cho ứng dụng AI thực tế.

Raspberry Pi Locator Website To Shut Down In July

Rpilocator.com, a popular site tracking Raspberry Pi stock and pricing across online retailers, is shutting down in July 2026. The main reason is that the site's indexing bot has been blocked by most shopping sites, likely due to anti-scraping measures aimed at AI bots. The site still serves around 11,000 monthly users but the effort to maintain workarounds became unsustainable. The closure also reflects a broader shift in the single-board computer landscape: the chip shortage era that made such a tracker essential has passed, replaced by concerns over rising memory prices pushing Raspberry Pi boards into luxury price territory.

I run Snapcast on a stack of Raspberry Pis instead of paying for Sonos

A hands-on account of building a DIY multi-room audio system using Snapcast on Raspberry Pis as an alternative to spending $1000+ on Sonos hardware. Snapcast acts as a music distribution layer, streaming audio with embedded timestamps to multiple Snapclient devices for synchronized playback across rooms. The setup uses a Pi 4 as the Snapserver connected via Ethernet, with older Pi models (including Pi Zero 2 W) running Snapclient over Wi-Fi. USB DAC adapters or HiFiBerry HATs improve audio quality cheaply. The tradeoff is manual configuration via SSH and config file editing instead of a polished app, but the result is hardware you own with no vendor lock-in, plus optional AirPlay (Shairport Sync) and Spotify Connect (Raspotify) integration.

The Special Value Pi 4 was extremely short-lived

A Raspberry Pi reseller briefly listed a 'value edition' Pi 4 certified to run at only 1.25 GHz instead of the standard 1.8 GHz, priced at $89 before shipping and tariffs. The listing was quickly pulled, likely because the boards are externally identical to retail units. Benchmarking revealed that the 4GB unit actually booted and ran at 1.8 GHz, while the 8GB unit required being locked to 1.25 GHz to avoid kernel panics. Both units drew more power at idle (~3W vs under 2W) due to DVFS requiring higher voltages to maintain stability on lower-binned silicon. A Raspberry Pi engineer explained that less than 0.01% of boards fail standard validation and are set aside for industrial customers who understand the trade-offs, avoiding e-waste while offering a slight discount.
