GEEKOM A5 Pro 2026 Edition mini PC Ubuntu 25.10 linux review

After checking out the hardware with an unboxing and a teardown of the GEEKOM A5 Pro 2026 Edition mini PC, and testing it with the pre-installed Windows 11 Pro OS in the second part of the review, we will now report our experience with Ubuntu 25.10 to show how the AMD Ryzen 5 7530U mini PC performs under Linux. The Ubuntu 25.10 review includes an overview of the system, benchmarks, storage and networking (2.5GbE and WiFi 6) performance testing, and measurements of CPU temperature under stress, fan noise levels, and power consumption of the mini PC under various workloads. Ubuntu 25.10 installation We decided to install Ubuntu 25.10 in dual boot configuration alongside Windows 11. To do so, we first shrank the Windows partition (C:) to roughly half its original size, before inserting a USB drive with the Ubuntu 25.10 ISO to carry on with the installation. The installation proceeded […]

Pironman 5 Pro Max Raspberry Pi 5 Case Adds 4.3-inch Touchscreen, Camera Mount, Speakers, Microphone, and More – CNX Software

Pironman 5 Pro Max case

Pironman 5 Pro Max is the latest Raspberry Pi 5 case by SunFounder. The new enclosure adds a 4.3-inch capacitive touchscreen display, a 5MP camera module, a mount suitable for Raspberry Pi Camera Modules, stereo speakers, a USB microphone, and a 3.5mm audio jack. Besides the new features, its design is close to the Pironman 5 Max we reviewed with a Raspberry Pi 5, an NVMe SSD, and an Hailo-8 AI accelerator last June. That means it keeps black aluminum and semi-transparent black acrylic panels, offers two M.2 PCIe slots, an IR receiver, a power button, and the Tap-to-Wake feature for the OLED information display. Pironman 5 Pro Max specifications: Designed for the Raspberry Pi 5 and compatible SBCs Storage Pironman 5 Dual NVMe PiP supporting 2x M.2 2230, 2242, 2260, or 2280 NVMe SSDs at up to PCIe 2.0 x1 speeds due to switch used; RAID 0/1 support MicroSD […]

SayoDevice O3C 3-Key Hall-Effect Keypad Features 8,000Hz Polling Rate for Rhythm Games – CNX Software

SayoDevice O3C

While searching for new products on AliExpress, I came across the SayoDevice OSU O3C, which looks very similar to other macro keyboards such as the 4xMacropad, the LILYGO TTGO T-Encoder, or the T-Keyboard-S3. However, like the TENSTAR T-Display, it sold over 10,000 pieces on Aliexpress. This warranted an investigation, and I found that it is actually a Hall-effect keypad mainly designed for rhythm and single-input games such as osu! and Geometry Dash. The keypad features OUTEMU magnetic Hall-effect switches with rapid trigger support and a customizable actuation point as low as 0.05 mm, for extremely fast and precise keystrokes. The keyboard connects to a PC via a USB 2.0 cable and supports an 8,000 Hz polling rate for low input latency. The device includes a 0.96-inch IPS color display that can show key travel information, key press counts, or custom images and text, and the first line of the screen […]

Makerfabs CM0IQ: An Ultra-Compact Raspberry Pi CM0 Lite Board (42x36mm) – CNX Software

Raspberry Pi CM0IQ top and bottom

The CM0IQ is an ultra-compact board based on the Raspberry Pi CM0 Lite Compute Module. It measures just 42 × 36 mm and squeezes multiple interfaces into a 15.1 cm² footprint, making it suitable for space-constrained applications such as robotics, IoT devices, and custom hardware integrations. Despite being smaller than a Raspberry Pi Zero 2 W (19.5 cm²), the CM0IQ manages to include a full-sized USB-A port, a Micro HDMI port, and 4-lane MIPI CSI and DSI connectors. To fit everything into this small footprint, the designer also relied on a 1.27 mm 40-pin GPIO header rather than the standard 2.54 mm header. The board also features a USB Type-C for power, a microSD card slot for storage, 5V solder pads for power input, and four M2 mounting threads. Raspberry Pi CM0IQ Specifications: SoM – Raspberry Pi CM0 Lite SoC – Broadcom BCM2710A1 CPU – Quad-core Cortex-A53 processor @ 1.0 GHz […]
