The board is powered by the WCH CH32V317WCU6, a RISC-V microcontroller capable of running at up to 144MHz. The chip features a USB 2.0 high-speed controller alongside a full-speed controller, a 10/100M Ethernet MAC with a physical layer transceiver, SDIO support, DVP for digital video input, and advanced motor PWM timers.
The September 20th release of DietPi v9.17 introduces smaller and more efficient system images, faster backups with reduced disk usage, and a new toggle for Roon Server’s early access builds. The update also addresses SPI bootloader flashing issues on Rockchip devices, improves Raspberry Pi sound card handling, and includes multiple bug fixes across tools and software.
The EdgeXpert achieves up to 1000 AI TOPS at FP4 precision with sparsity and can scale higher using FP8 data formats. It integrates 128 GB of unified LPDDR5x memory on a 256-bit interface, offering 273 GB/s bandwidth shared across the CPU and GPU.
The firmware supports protocols such as I²C, SPI, UART, 1-Wire, CAN, and JTAG, as well as infrared, smartcards, and USB device emulation. It also extends to wireless communication, enabling interaction with Sub-GHz radios, Bluetooth, Wi-Fi, RFID, and RF24 devices. A built-in scripting engine allows automation using Bus Pirate-style bytecode instructions or Python.
This is the second compilation of our Ubuntu 24.04 Noble Numbat tutorials which have been published here at The Ubuntu Buzz since 2024. In last compilation, we talked about downloading Ubuntu up to selecting our repository server among others. In this episode, we will remind you about CHM ebooks, AppImages, Telegram Desktop as well as the classic but powerful Synaptic Package Manager with a short review for each. We hope this compilation series will be useful to you and everyone. This marks our last article of that year in the month May. Please enjoy!
Powered by the latest and greatest Linux 6.16 kernel series, KaOS Linux 2025.09 ships with the KDE Plasma 6.4.5 desktop environment, which is accompanied by the latest KDE Gear 25.08.1 and KDE Frameworks 6.18 software suites, all built using the latest Qt 6.9.2 open-source application framework.
The Raspberry Pi 500+ is the successor of the Raspberry Pi 500 computer, based on the Raspberry Pi 5 16GB model and featuring a high-quality mechanical keyboard with removable keycaps and individually addressable RGB LEDs, as well as an internal M.2 socket equipped with a 256GB Raspberry Pi SSD.
Coming almost three months after Ubuntu Touch OTA-9, the Ubuntu Touch OTA-10 release introduces support for the Rabbit R1 device and the new Ubuntu Touch upgrader, which allows users to upgrade to the long-anticipated Ubuntu Touch 24.04-1.0 release, based on Ubuntu 24.04 LTS, once it’s released.
Highlights of Calibre 8.11 include a new “Ask AI” tab in the dictionary lookup panel that allows you to query AI about the currently selected text. The feature supports hundreds of AI models via free providers like Google, OpenRouter, GitHub, or locally via Ollama.
It’s been more than a year since System76 started development on Pop!_OS 24.04 LTS with the Rust-based desktop environment when they released the first alpha version, and now, seven alphas later, the beta version is ready for public testing for early adopters and application developers.
