Realtek RTL8159 10GbE to USB 3.2 adapters sell for about $55 and up

Realtek unveiled low-cost, low-power 10GbE RTL8127 (PCIe) and RTL8159 (USB 3.0) controllers at Computex 2025. Since then, we noted that RTL8127-based M.2 and PCIe 10GbE cards had already launched for as low as $35. However, a new X post by Jeff Geerling reminded me it was time to check on those RTL8159 10GbE to USB 3.2 adapters. So let’s do that now, starting with the Wisdpi WP-UT9 mentioned in the post/tweet. Wisdpi WP-UT9 WisdPi WP-UT9 specifications: Chipset – Realtek RTL8159 Ethernet – Up to 10GbE RJ45 port; backward compatible with 5 Gpbs, 2.5 Gbps, 1Gbps, and 10/100Mbps Ethernet USB –...

SupTronics X1208 – A UPS + M.2 NVMe SSD HAT for the Raspberry Pi 5

The SupTronics X1208 is a UPS and M.2 NVMe SSD HAT for Raspberry Pi 5 designed to offer fast storage and protect the system against data loss during power outages for Edge Computing, NAS, data logging, and other always-on applications. The HAT draws up to 5V/5A from the USB-C port, which charges a 21700 lithium-ion battery (1.5A) and powers the Raspberry Pi 5 directly through the 40-pin GPIO header, eliminating the need for extra cables. It also features an M.2 M-key NVMe slot supporting 2230/2242/2280 SSDs up to 4TB with PCIe 2.0/3.0 speeds. The UPS supports power switching, auto power-on,...

Кто и как узнаёт, что ваш лифт застрял?

Приветствую всех!

Все мы наверняка видели кнопку вызова диспетчера в каждой кабине лифта. Думаю, каждому из нас нет-нет, да хотелось однажды её нажать. А кому-то, возможно, и доводилось это делать по какой-то весомой причине.

Сегодня же мы посмотрим, что стоит за возможностью сообщить о неисправности лифта в любой момент нажатием одной-единственной кнопки. Посмотрим на само оборудование и, конечно, попробуем его запустить. Как оказалось, всё это намного сложнее, чем я думал…

Nuvoton NuMicro M3331 Cortex-M33 MCU features built-in ARGB LED controller, optional USB 2.0 OTG interface

Nuvoton’s new NuMicro M3331 is a series of 32-bit Arm Cortex-M33 MCUs clocked at 180 MHz that integrate an ARGB LED controller, a DSP instruction set, a single-precision FPU, and TrustZone security for smart factories, renewable energy systems, and consumer devices. In the past, we have written about other Cortex-M33 MCUs like the STM32U3B5/C5, Texas Instruments MSPM33C321A,  Nordic Semi’s nRF54LM20A, and various others, but the Nuvoton M3331 series specifically features a built-in Enhanced LED Light Strip Interface (ELLSI) and up to 10 standard LLSI channels. This allows the MCU to natively support gaming ARGB Gen1 and Gen2 LED control protocols,...
