LibreELEC 11 released with Kodi 20, brings back Amlogic platforms

LibreELEC 11 lightweight media center Linux distribution based on Kodi 20 “Nexus” has just been released with various improvements on x86 and Arm platforms. Kodi 20 was released and available for download in January with AV1 hardware video decoding in Android and x86 (VAAPI) platforms with AV1-capable GPU or VPU, FFMPEG 4.4, Pipewire support in Linux, and a few others. LibreELEC 11 enables you to have a dedicated, and fast booting, HTPC based on a mini PC, a Raspberry Pi SBC, or an Arm-based TV box with all features from the latest Kodi release. LibreELEC 11 supports Raspberry Pi 2 to 4 SBCs, 64-bit x86 hardware, various Allwinner, Rockchip, and Amlogic SBCs and TV boxes with x86, Raspberry Pi, and Rockchip hardware considered more stable and feature complete. LibreELEC 10.0 did away with Amlogic TV boxes and single board computers because of driver issues, but LibreELEC 11.0 brings Amlogic back […]

Riotee batteryless stackable IoT board embeds an nRF52833 module (Crowdfunding)

Nessie Circuits’ Riotee board features a Riotee module based on Nordic nRF52833 WiSoC with a 2.4 GHz radio that targets batteryless IoT applications thanks to a stackable design taking a capacitors add-on board and a solar panel. Batteries introduce maintenance costs and environmental issues with millions of batteries disposed of every day. That’s why companies are trying to provide solutions for batteryless IoT designs such as the Everactive batteryless IoT devkit or Telink energy harvesting wireless module for remote controls. The Riotee module, board, and ecosystem also aim to play their part in reducing the use of batteries in wireless IoT devices. Riotee board specifications: Riotee module Wireless MCU – Nordic nRF52833 Arm Cortex-M4F microcontroller @ 64 MHz with 512 kB flash, 128 kB RAM, 2.4 GHz radio Memory – 128 kB of non-volatile memory (MSP430FR5962 FRAM) for “automatic checkpointing of application state” Castellated holes with 11x GPIOs including two […]

Beelink SER6 Pro mini PC review – Windows 11, Ubuntu 22.04, and USB4

Beelink upgraded their earlier SER6, which used an AMD Ryzen 5 6600H processor with integrated AMD Radeon 660M graphics, and released the SER6 Pro which has a faster AMD Ryzen 7 6800H processor with much more powerful integrated AMD Radeon 680M graphics. Beelink kindly sent a SER6 Pro unit for review however since receiving the mini PC, Beelink have ‘refreshed’ the processor to use an AMD Ryzen 7 7735H also with AMD Radeon 680M graphics, and called it the SER6 Pro Refresh. As a result, this review looks at Windows performance which should be indicative for both versions, together with a quick look at running Ubuntu and also a more detailed look at the USB4 port which is a new inclusion to Beelink’s mini PCs. Update: you may be interested in the review of the Beelink SER6 Pro 7735HS – in Windows 11 only – as we’ve also received it […]
