CNX Software reports that LILYGO has released the T-ETH-Lite ESP32-S3, a development board that features WiFi, Bluetooth, and Ethernet connectivity.

The board includes a low-profile Ethernet RJ45 connector with a WIZnet W5500 Ethernet controller and supports Power over Ethernet (PoE) with an additional shield. It also comes equipped with a microSD card slot and expansion I/Os. The T-ETH-Lite ESP32-S3 is based on the ESP32-S3-WROOM-1 wireless module, which features an ESP32-S3 dual-core LX7 microprocessor running at up to 240 MHz and 8MB of PSRAM. It also has 16MB of SPI flash storage and supports WiFi 4 and Bluetooth 5 with LE/Mesh. The board has 2x 15-pin headers with up to 23x GPIOs, 2x UART, 14x ADC, touch interface, reset, 5V, 3.3V, and GND. It measures 59 x 28 x 11 mm.

LILYGO provides a range of Arduino samples for the T-ETH boards, including web server, firmware updates, MQTT server, and more. The T-ETH-Lite ESP32-S3 board is available now on AliExpress. In a home lab environment, the T-ETH-Lite ESP32-S3 with its Ethernet port and PoE support could probably be used to develop an interesting monitoring device, for example.

Intel has recently announced Thunderbolt 5, the latest iteration of their high-speed connectivity technology. With up to 120 Gbps bandwidth when using “Bandwidth Boost,” Thunderbolt 5 offers significant improvements over its predecessor.

The key features of Thunderbolt 5 include:

• 80 Gbps of bi-directional bandwidth, with the option to boost it to 120 Gbps for video-intensive usage.
• Double the PCI Express data throughput, resulting in faster storage and external graphics performance.
• Compatibility with USB4 V2, DisplayPort 2.1, and PCI Express Gen 4.
• Double the bandwidth of Thunderbolt Networking for high-speed PC-to-PC connections.
• PAM-3 signaling technology that enhances performance with existing circuit boards, connectors, and passive cables up to 1 meter.

Thunderbolt 5 is aimed at meeting the needs of content creators, gamers, and professionals who require high-speed connectivity. While it may take some time for Thunderbolt 5 to become prevalent in mini PCs, its adoption is expected to increase as the demand for faster storage and high-performance eGPU grows.

Premium PCs and laptops are likely to integrate Thunderbolt 5 soon, as Intel’s controller, codenamed Barlow Ridge, is set to be available in 2024.

For storage enthusiasts and those building home servers, Thunderbolt 5 offers an exciting prospect. Its increased bandwidth and compatibility with USB4 V2 make it a suitable choice for high-speed data transfer and storage solutions. Additionally, Thunderbolt 5’s ability to support multiple 8K monitors opens up possibilities for multi-display setups in server or network environments.

It’s worth noting that Thunderbolt 5’s potential for storage extends beyond traditional setups. For instance, AWS has adopted Thunderbolt for their Apple Silicon Mac mini datacenter offering, utilizing its capabilities for high-speed storage.

For more detailed information on Thunderbolt 5, refer to Intel’s press release and the product page.

Until now, the content on this site has mostly been related to software, but in the coming weeks, hardware content will also be produced and added. The hardware content will discuss deciding what hardware you need and how to source the components needed. The content will also deal with customizing servers and may include some 3D printing-related posts. 😊

The software articles on the site will also be updated over the coming months, with posts being revised for newer software versions and similar.

Feels good to be back!

I’ve assembled a list of useful single-board computers (SBCs) for use in home labs. They are essentially low-power computers useful for lightweight tasks and experimentation. I’ve used them (and still do) for certain tasks, especially when I’ve wanted to experiment with various things on the ARM64 platform. FriendlyARM Nano-Pi M4 (6 ARM64 cores, 2/4GB LPDDR3/LPDDR4 RAM) – a handy board for storage applications. It features a PCI Express interface, allowing for multiple SATA ports using the SATA hat or an NVMe drive using the NVMe hat.

This tutorial will show you how to easily remove the desktop interface from your NVIDIA Jetson Nano Developer Kit to run it in headless mode. This can be useful for using the NVIDIA Jetson Nano as a small, low-power server with machine-learning capabilities. The NVIDIA Jetson Nano is a mighty little single-board computer with a Quad Core ARM64 CPU, 4GB LPDDR4 RAM, and a 128-core NVIDIA Tegra (Maxwell-based) GPU, all while using as little as 5 watts.
