FOSDEM 2023 schedule – Open-source Embedded, Mobile, IoT, Arm, RISC-V, etc… projects

After two years of taking place exclusively online, FOSDEM 2023 is back in Brussels, Belgium with thousands expected to attend the 2023 version of the “Free and Open Source Developers’ European Meeting” both onsite and online. FOSDEM 2023 will take place on February 4-5 with 776 speakers, 762 events, and 63 tracks. As usual, I’ve made my own little virtual schedule below mostly with sessions from the Embedded, Mobile and Automotive devroom, but also other devrooms including “Open Media”, “FOSS Educational Programming Languages devroom”, “RISC-V”, and others. FOSDEM Day 1 – Saturday February 4, 2023 10:30 – 10:55 – GStreamer State of the Union 2023 by Olivier Crête GStreamer is a popular multimedia framework making it possible to create a large variety of applications dealing with audio and video. Since the last FOSDEM, it has received a lot of new features: its RTP & WebRTC stack has greatly improved, Rust […]

GL.iNet Beryl AX OpenWrt router review – WiFi 6 performance, repeater, NAS, and 4G hotspot modes

Power bank GL.iNet GL-MT3000 Beryl AX router

In the first part of the review of GL.iNet GL-MT3000 “Beryl AX” pocket-size WiFi 6 OpenWrt router we had a look at the specifications, the package content, and the hardware design with a teardown of the little router. I’ve now had more time to play with the router focusing the review on WiFi 6 performance, and some of its functions such as repeater, NAS, and 4G hotspot. The router also supports VPN client and server modes, the Tor network, and Adguard Home, but I’ll invite readers to check out the GL.iNet Brume 2 security gateway review since I went through all these, and the hardware is very similar minus wireless connectivity. Initial setup of the Beryl AX router If you connect an Ethernet cable to the router you can switch to step two. If you only rely on WiFi for the setup that works too as the Beryl AX router […]

Allwinner TV303 quad-core Cortex-A53 “Smart Screen” processor is made for projectors

Previously known for its tablet SoCs, Allwinner has been focusing on low-cost Cortex-A7 and Cortex-A53 processors for consumer devices in recent years, and the Allwinner TV303 quad-core Cortex-A53 processor is yet another one and appears to be the first of Allwinner TV-series processors designed for “smart screens”, notably smart Android projectors. I could not find any references for TV303 on the Allwinner website, but the company did publish a post on Weixin about a “Smart Android Projector” by Hotack based on the new processor and showcased at CES 2023. Allwinner TV303 preliminary specifications: CPU – 4x Arm Cortex-A53 GPU – Arm Mali-G31 VPU – 4K hardware video decoding + image quality engine Video Output – Up to Full HD Video Input – HDMI input The projector itself features two stereo speakers, WiFi 6 connectivity, and can be turned into a Bluetooth speaker. It also supports keystone correction and autofocus. Allwinner […]

Intel kills PathFinder IDE for RISC-V processors

Intel has just discontinued PathFinder Eclipse-based development environment for RISC-V processors with the website now reading: We regret to inform you that Intel is discontinuing the Intel Pathfinder for RISC-V program effective immediately. Since Intel will not be providing any additional releases or bug fixes, we encourage you to promptly transition to third-party RISC-V software tools that best meet your development needs. PathFinder was a pre-silicon open-source development environment with support for vairous RISC-V cores, a set of other IP’s, multiple operating systems, and toolchains. It allowed designers to create RISC-V SoCs to and run them on FPGA platforms such as the Terasic developer kit or Startix-10 GX evaluation kit. PathFinder appears to just be one of the casualties after Intel reported a loss for Q4 2022, and announced it will lose even more in Q1 2023 with Tom’s Hardware also highlighting Intel would stop investing in new products for […]

LILYGO T-QT Pro 0.85-inch WiFi IoT display adds support for battery charging

LILYGO T-QT Pro is an ESP32-S3 WiFi and BLE IoT board with a 0.85-inch color display, 4MB flash, 2MB PSRAM, a USB-C port, a few GPIOs, and support for LiPo battery with charging. It is an upgrade to the ESP32-S3-based LILYGO T-QT V1.1 board that also supports LiPo battery power but lacks a charging circuit, so you had to remove the battery and charge it manually each time. The T-QT Pro adds a charging circuit and switches from an ESP32-S3 with an 8MB flash design to one using ESP32-S3FN4R2 with 4MB flash and 2MB PSRAM. LilyGO T-QT Pro specifications: Wireless MCU – Espressif Systems ESP32-S3FN4R2 dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration, 512KB RAM, 4MB flash, 2MB PSRAM, wireless connectivity Connectivity via ESP32-S3 2.4 GHz 802.11 b/g/n Wi-Fi 4 with 40 MHz bandwidth support Bluetooth Low Energy (BLE) 5.0 connectivity with long-range support, […]

ESP32 OpenMQTTGateway smart plug acts as an BLE MQTT gateway and a power meter

The Theengs Plug ESP32 smart plug runs OpenMQTTGateway firmware to serve as a BLE MQTT gateway and power meter compatible with Home Assistant, Homebridge, OpenHAB, DomoticZ, FHEM, Jeedom, NodeRed, AWS, and any MQTT-compatible IoT or Smart Home system. While the Matter standard should improve interoperability between Smart Home frameworks over time, there are still millions of devices already produced that are not Matter compatible, and the Theengs Plug aims to at least partially address this issue by helping users reduce the number of hubs required and have only one that supports different ecosystems. Theengs Plug hardware specifications: Microcontroller – ESP32 dual-core wireless MCU with 2.4 GHz WiFi and Bluetooth LE connectivity Network Protocol – MQTT Power Supply – 100-120VAC, 60Hz, up to 15A Dimensions – 103 x 61 x 34.6mm Temperature Range – Operating: 0ºC ~ 40ºC; storage: -10°C ~ 50°C Humidity – 0%～95% (no condensation) Certification – UL Some […]
