Radxa Orion O6 Preview – Part 2: Debian 12 – What works, what doesn’t

I went through an unboxing and Debian 12 installation on the Radxa Orion O6 at the end of January, but decided to work on other reviews since software support still needed to be worked on. Since then, there’s been some work done, but no new image released. After waiting for almost two months, I’ve decided to carry on with the review by testing the Debian 12 image in a way similar to the Rock 5B SBC preview I did with Debian 11 in 2022 to check what works and what doesn’t on the Orion O6 at the time of the review. That will involve testing all ports, including 5GbE networking and the PCIe slot with an (old) NVIDIA graphics card, running some benchmarks, and also trying the Debian 12 image with a self-built Linux 6.13 kernel using ACPI instead of UEFI for the default image. Orion O6 SBC benchmarks on […]

QuadClock PCB – An ESP32-S3 multi-display clock controller for DIY enthusiasts

The QuadClock PCB is an ESP32-S3-powered multi-display clock controller designed to serve as a foundation for creating a four-TFT-display clock. It supports up to four 1.69-inch rectangular TFT displays (240×280) or four 1.28” round displays (240×240). It manages essential functions such as driving the displays and maintaining precise time, allowing you to focus on crafting a unique enclosure or integrating additional features. It is open-source and is powered by the ESP32-WROOM-1 module with up to 16MB flash and 2MB PSRAM. It supports independent brightness control for each mounted display via four MOSFETs and includes an onboard real-time clock with a backup battery for accurate timekeeping. The QuadClock PCB is designed for enthusiasts and makers interested in creating multi-display clock projects. It can also be used for stock tickers, weather displays, and smart home dashboards. We previously covered the 2×2 Quad Display board with either Raspberry Pi Pico W or ESP32-S3-WROOM-1 […]

Khadas Mind Maker Kit review – Part 2: Windows 11 Home on an Intel Core Ultra 7 258V AI mini PC

I’ve already gone through the specifications and an unboxing of the “Khadas Mind 2 AI Maker Kit” powered by an Intel Core Ultra 7 258V “Lunar Lake” processor delivering up to 115 TOPS of AI performance and equipped with 32GB LPDDR5X RAM and a 1TB M.2 NVMe SSD in the first part of the review. I’ve now spent time with the mini PC/developer kit which is now simply called “Khadas Mind Maker Kit”, and I will report my experience with the Windows 11 Home 24H2 operating system in the second part of the review testing features, running benchmarks including an AI benchmark, evaluating networking and storage performance, testing the thermal design while under stress, and taking measurements for fan noise and power consumption. It looks like some AI features may finally be usable on Windows, but I’ll test that in a separate post since everything is new and Microsoft Copilot+, […]

4D Systems Raspberry Pi RP2350 display modules come in touch and non-touch options for embedded applications

4D Systems, an Australian company specializing in intelligent display solutions, has released Raspberry Pi RP2350-powered display modules with touch and non-touch options. The display modules are available in eight different sizes from 2.4-inch to 9.0-inch and different resolutions from 240×320 up to 800×480 pixels. They are “Powered by Raspberry Pi”-certified and leverage the Raspberry Pi RP2350’s dual-core architecture and security features for “secure, professional-grade applications that require modern UI”. 4D Systems is well-known for its high-quality displays designed for developers looking to create sophisticated user interfaces in embedded systems. There are four touch panel options for each gen4-RP2350 display module: non-touch, resistive touch, capacitive touch, and capacitive touch with a cover lens bezel (CLB). The gen4-RP2350 series also features a 30-pin FPC/ZIF socket to fit a 0.5mm pitch FFC for connecting a motherboard or accessory board. We have already covered Waveshare’s RP2350-LCD-1.28 display module but the gen4-RP2350 display modules are […]

Khadas Mind Graphics NVIDIA RTX 4060 Ti GPU dock for the Mind mini PC is now available for $999

The Khadas Mind Graphics is a dock for the Khadas Mind Raptor Lake mini PC that integrates an NVIDIA Geforce RTX 4060 Ti GPU and enables users to run high-end games, edit videos, design graphics, and experiment with AI while keeping the portability and small size of a mini PC. As we’ve seen in our reviews, mini PCs now match the performance of larger machines in almost all aspects with tools like PassMark Performance showing higher-end models’ CPU, memory bandwidth, and storage in the top 10% or 20% of systems. The exception is 3D graphics performance because integrated GPUs can’t match the performance of higher-end graphics cards. The Khadas Mind Graphics solves that by adding an NVIDIA Geforce RTX 40601 Ti GPU to the Khadas Mind mini PC through its Mind Link connector also bringing out other connectors such as 2.5GbE, USB, SD card, etc… Khadas Mind Graphics specifications: Graphics […]

7-inch ESP32-S3 touchscreen display exposes RS485, CAN Bus, I2C, UART, and analog sensor interfaces

Waveshare ESP32-S3-Touch-LCD-7 is an ESP32-S3 powered WiFi 4 and Bluetooth 5 LE 7-inch touchscreen display with plenty of expansion interfaces such as RS485, CAN Bus, I2C, UART, and Analog input that can be used to develop various HMI applications We’ve written about many ESP32 boards with displays, but most are small displays under 3-inch, and larger displays are more of a rarity except for ESP32 e-Paper displays such as the Inkplate 10 or LILYGO 7.5-inch e-Paper display. Most are based on ESP32-S3 since it comes with an RGB LCD interface, and the only other 7-inch ESP32-S3 touchscreen display we’ve looked into is the Elecrow 7.0-inch display with specifications similar to the Waveshare ESP32-S3-Touch-LCD-7, but fewer I/O headers. Waveshare ESP32-S3-Touch-LCD-7: Wireless module – ESP32-S3-WROOM-1 MCU – ESP32-S3N8R8 dual-core Tensilica LX7 up to 240 MHz with 512KB SRAM, 8MB PSRAM, 8MB flash Wireless – 2.4 GHz WiFi 4 and Bluetooth LE 5 […]

Google’s Jpegli open-source library can compress high quality images 35% more than traditional JPEG codecs

Jpegli ELO score vs other JPEG libraries

Google has released the Jpegli open-source library for advanced JPEG coding that maintains backward compatibility while delivering an up to 35% compression ratio improvement at high-quality compression settings. Google Research has been working on improving the compression of data (Brotli), audio (e.g. Lyra V2), and images with a project such as WebP for many years in order to speed up the web and make it consume less bandwidth for dollar savings and lower carbon emissions. Jpegli is their latest project and aims to improve the compression ratio of legacy JPEG files on systems were modern compression such as WebP may not be available or desirable. Jpegli highlights: Support both an encoder and decoder complying with the original JPEG standard (8-bit) and offering API/ABI compatibility with libjpeg-turbo and MozJPEG. Focus on high-quality results with up to 35% better compression ratio. Just as fast as libjpeg-turbo and MozJPEG. Support for 10+ bits […]
