Review of Arylic H50 wireless stereo amplifier with TIDAL Music

Arylic H50 review

We’ve recently completed the review of the Arylic BP50 Bluetooth preamplifier where we tested the audio quality while streaming audio from the TIDAL Music app. But RAKOIT also sent us the Arylic H50 wireless stereo amplifier for review, and we’ll report on our experience with that device today using the TIDAL Music app again. The H50 is an audio streaming player with a digital-to-analog (DAC) converter chip and a built-in power amplifier. It supports wireless networks such as WiFi and Bluetooth and plenty of wired connections namely analog RCA line In, analog RCA phono In, digital optical in, Subwoofer out, RJ45 LAN port, HDMI ARC, USB Type-A Host, and USB Type-C. To use the Arylic H50, simply connect the output signal cable to stereo speakers (passive speaker) with 50 watts of output power on each side, allowing you to stream music from various services through the 4STREAM app or Spotify, […]

Mixtile Cluster Box supports four Rockchip RK3588 SBCs connected over PCIe

Mixtile Cluster Box

The Mixtile Cluster Box is comprised of four Mixtile Blade 3 Pico-ITX single board computers each powered by a Rockchip RK3588 processor and connected over a 4-lane PCIe Gen3 interface through a U.2 to PCIe/SATA breakout board. We mentioned the Cluster Box last year, but Mixtile had few details about it at the time. The company has now released more technical information, worked on the software, and just launched the box for $339 (without the SBCs). Mixtile Cluster Box specifications: Supported SBCs – Up to 4x Mixtile Blade 3 with Rockchip RK3588, up to 32GB LPDDR4 each, up to 256GB eMMC flash each Control board running OpenWrt 22.03 SoC – MediaTek MT7620A MIPS processor @ 580 MHz System Memory 256 MB DDR2 Storage – 16 MB SPI Flash PCIe Switch – ASMedia ASM2824 with four PCIe 3.0 4-lane ports Storage interfaces via 4x U.2 breakout boards 4x NVMe M.2 M-Key […]

microSD Express memory cards to support up to 2GB/s data transfers

microSD Express 2GB per second

SD Association (SDA) has announced the new SD 9.1 specification that doubles the speed of microSD Express memory card speed up to 2GB/s, defines four new SD Express Speed Classes to ensure guaranteed minimum sequential performance levels, and adds support for multi-stream access and related power and thermal management to assure the guaranteed performance. We first covered the microSD Express cards in 2019 as they were added to the SD 7.0 specification with promises of SSD performance through a PCIe 3.0 interface delivering up to 985MB/s. Over four years have passed since then, and I have yet to write about devices supporting the new standard, but the SD Association is not giving up with the introduction of the SD 9.1 specification that doubles the speed of the microSD Express cards, and full-size SD Express card can even reach close to 4GB/s. More specifically, the maximum speed achievable on microSD Express […]

Generative AI on NVIDIA Jetson Orin, Jetpack 6 SDK to support multiple OSes

Jetson Orin Generative AI

NVIDIA has had several announcements at ROSCon 2023 related to robotics & embedded with highlights including generative AI on the NVIDIA Jetson Orin module and the Jetpack 6 SDK will be released next month (November 2023) with supports for Ubuntu as usual, but also other operating systems and platforms such as Debian, Yocto, Wind River, Redhawk RTOS, and Balena. Generative AI on NVIDIA Jetson Orin There’s been a lot of hype in the last year about generative AI thanks to services such as ChatGPT, Google Bard, or Microsoft Bing Chat. But those rely on closed-source software that runs on powerful servers in the cloud. As we noted in our article about the “AI in a box” offline LLM solution there are some open-source projects such as Whisper speech-to-text model and Llama2 language models that could be run on embedded hardware at the edge, but as noted by some readers platforms […]

SiFive announces Intelligence X390 NPU, Performance P870 RISC-V core

SiFive Performance P870 RISC V Intelligence X390 NPU

SiFive has announced two new high-performance IP blocks with the Intelligence X390 NPU and the Performance P870 RISC-V core that should find their way into SoC designed for Generative AI and ML applications. We had already covered the Performance P870 and its automotive sibling – the P870-A – from information in an earlier presentation, but the SiFive Intelligence X390 NPU is new to me and appears to be aimed at generative AI in data centers, although we will very soon be seeing companies implement generative AI at the edge in pretty powerful embedded devices. SiFive Performance P870 highlights: Full support for the RVA23 RISC-V profile specification and Vector 1.0 and Vector Crypto Six-wide, out-of-order 64-bit core Up to a 32-core cluster >12 SpecINT2k6/GHz, or a 50% peak single thread performance upgrade over the previous generation SiFive Performance P670 SiFive Features 2x 128b VLEN RVV Vector crypto and hypervisor extensions IOMMU […]
