LILYGO T-ETH-Lite – An ESP32-S3 board with Ethernet, optional PoE support

LILYGO T-ETH-Lite ESP32-S3 is a new ESP32-S3 WiFi and Bluetooth development board with a low-profile Ethernet RJ45 connector using a WIZnet W5500 Ethernet controller, supporting PoE with an extra shield, and also equipped with a microSD card socket and expansion I/Os. ESP32-based development boards with Ethernet have been around for years including LILYGO’s own “TTGO T-Lite W5500“, but so far we haven’t many based on the more recent ESP32-S3 microcontroller except for the SB Components’ ESPi board that we covered last April. But LILYGO T-ETH-Lite ESP32-S3 adds another cost-effective board with Ethernet. LILYGO T-ETH-Lite ESP32-S3 specifications: Wireless module ESP32-S3-WROOM-1 MCU – ESP32-S3 dual-core LX7 microprocessor @ up to 240 MHz with Vector extension for machine learning Memory – 8MB PSRAM Storage – 16MB SPI flash Connectivity – WiFi 4 and Bluetooth 5 with LE/Mesh PCB antenna Storage – MicroSD card slot Connectivity 802.11 b/g/n WiFi 4 up to 150 Mbps and […]

Review of Youyeetoo Rockchip RK3568 SBC with Lubuntu 20.04 and the RKNPU2 AI SDK

We’ve already reviewed the Rockchip RK3568-power Youyeetoo YY3568 SBC with Android 11 – and listed the specifications and checked out the hardware kit – in the first part of the review. We now had time to switch to Lubuntu 20.04, perform some basic tests, and also have a closer look at the RKNPU2 AI SDK for the built-in 0.8 TOPS AI accelerator found in the Rockchip RK3568 SoC. Installing Ubuntu or Debian on YY3568 SBC The company provides both Debian and Ubuntu images for the YY3568 SBC with different images depending on the boot device (SD card or eMMC flash) and video interface used (DSI, eDP, HDMI). Our YY3568 “Bundle 5” kit comes with an 11.6-inch eDP display so we’ll select the “Ubuntu 20” image with edp in the file name. The RKDevTool program is used to flash Linux images and it’s the same procedure as we used with Android […]

Orange Pi Compute Module 4 – A low-cost Rockchip RK3566-powered alternative to Raspberry Pi CM4

Orange Pi Compute Module 4 is a system-on-module mechanically and electrically compatible with the Raspberry Pi CM4, but powered by a Rockchip RK3566 quad-core Arm Cortex-A55 AI processor just like the Radxa CM3 introduced a few years ago, or more recently the Banana Pi BPI-CM2 (RK3568). The new module, also called Orange Pi CM4 for shorts, comes with 1GB to 8GB RAM, 8GB to 128GB eMMC flash, and an optional 128/256MBit SPI flash, as well as a Gigabit Ethernet PHY and on-board WiFi 5 and Bluetooth 5.0. It comes with the two 100-pin high-density connectors found on the Raspberry Pi CM4, and a smaller 24-pin connector for extra I/Os. Orange Pi Compute Module 4 specifications: SoC – Rockchip RK3566 quad-core Arm Cortex-A55 processor @ 1.8 GHz with Arm Mali-G52 2EE GPU, 0.8 TOPS AI accelerator, 4Kp60 H.265/H.264/VP9 video decoding, 1080p100f H.265/H.264 video encoding System Memory – 1GB, 2GB, 4GB, or […]

Linux 6.5 release – Notable changes, Arm, RISC-V and MIPS architectures

Linus Torvalds has just announced the release of Linux 6.5 on the Linux Kernel Mailing List (LKML): So nothing particularly odd or scary happened this last week, so there is no excuse to delay the 6.5 release. I still have this nagging feeling that a lot of people are on vacation and that things have been quiet partly due to that. But this release has been going smoothly, so that’s probably just me being paranoid. The biggest patches this last week were literally just to our selftests. The shortlog below is obviously not the 6.5 release log, it’s purely just the last week since rc7. Anyway, this obviously means that the merge window for 6.6 starts tomorrow. I already have ~20 pull requests pending and ready to go, but before we start the next merge frenzy, please give this final release one last round of testing, ok? Linus The earlier […]

MediaPipe for Raspberry Pi released – No-code/low-code on-device machine learning solutions

Google has just released MediaPipe Solutions for no-code/low-code on-device machine learning for the Raspberry Pi (and an iOS SDK) following the official release in May for Android, web, and Python, but it’s been years in the making as we first wrote about the MediaPipe project back in December 2019. The Raspberry Pi port is an update to the Python SDK and supports audio classification, face landmark detection, object detection, and various natural language processing tasks. MediaPipe Solutions consists of three components: MediaPipe Tasks (low-code) to create and deploy custom end-to-end ML solution pipelines using cross-platform APIs and libraries MediaPipe Model Maker (low-code) to create custom ML models MediaPipe Studio (no-code) webpage to create, evaluate, debug, benchmark, prototype, and deploy production-level solutions. You can try it out directly in your web browser at least on PC and I could quickly test the object detection on Ubuntu 22.04. MediaPipe Tasks can be […]
