Microchip launches LAN878x and LAN888x Single Pair Ethernet (SPE) transceivers with MACSec, TSN, and FuSA

Microchip’s LAN878x 100BASE-T1 and LAN888x 1000BASE-T1 Single Pair Ethernet (SPE) PHY transceivers are designed for secure, scalable, and deterministic Ethernet connectivity for automotive, avionics, robotics, and industrial systems. We first noticed Microchip SPE solutions in 2023 with the LAN8650/LAN8651 10BASE-T1S and LAN8770 100BASE-T1 transceivers, and they’ve launched other families since then, such as the LAN887x industrial Single Pair Gigabit Ethernet transceivers. The just-announced LAN878x/LAN88x parts introduce MACsec support, as well as Time Sensitive Networking (TSN) and FuSa (Functional Safety). Microchip LAN878x and LAN888x key features and specifications: Standard and port speed LAN878x – IEEE 802.3bw, 100BASE-T1 LAN888x – IEEE 802.3bp, 1000BASE-T1...

HomePod mini feels like magic, but it's just good timing

Apple introduced the HomePod mini six years ago, in 2020.

I'm not one into smart speakers, but the feature that made me take a closer look was their ability to form stereo pairs, without any direct wired connection.

I know there are other speaker manufacturers with wireless speakers, but to my knowledge, Apple was just using AirPlay over WiFi... so how does it work?

Through the magic of buying two HomePods mini (pictured above), I found out. A video detailing the process is embedded below:

6.67-inch flexible AMOLED display works with Raspberry Pi, LattePanda, and other SBCs with HDMI output

DFRobot has introduced a 6.67-inch flexible AMOLED display with a 2400×1080 resolution, designed for easy use with single-board computers such as Raspberry Pi and LattePanda. While flexible displays are common in smartphones, they are difficult to interface with SBCs, so DFRobot added a dedicated MIPI-to-HDMI driver board for plug-and-play compatibility with a wider range of platforms. The panel is just 1.2mm thick and bendable, enabling curved and space-constrained designs, while delivering 450 cd/m² brightness and 16.7 million colors. Like typical OLEDs, it offers deep blacks and high contrast without requiring a backlight, making it suitable for applications ranging from wearables...

ADSL. Откуда в телефонной линии берётся интернет?

Приветствую всех!

Застали ли вы интернет через ADSL? Когда-то давно для многих он был единственной возможностью получить сравнительно быстрый и стабильный доступ к сети. Сейчас же практически никто им не пользуется, а модемы отдаются за бесценок, потому что они уже никому не нужны.

И вот, спустя много лет, я решил попробовать сделать то, чего до меня практически никто не делал: раздобыть то самое оборудование, которое стояло у провайдера, запустить его и, наконец, поднять свою собственную домашнюю сеть и увидеть всё это в работе. Именно этим мы сейчас и займёмся. Заодно узнаем, как работает ADSL, а также вспомним, каким было посещение интернета в...

Khadas Mind Graphics 2 and Mind xPlay display + keyboard review – Part 1: Unboxing, teardown, and first try

Khadas has sent us the Mind Graphics 2 dock, Mind xPlay portable display and keyboard, as well as the Mind 2 mini PC for review. In the first part of the review, I’ll start by listing specifications, an unboxing of all three packages, a teardown of the graphics dock, and a first try of the xPlay and Mind Graphics 2 with the mini PC. While the Mind 2 will be used for testing, I won’t go into details here since it’s quite similar to the Mind 2 AI Maker Kit we reviewed last year. Instead, in the next parts, I’ll...

FalCAN Probe is an open-source, STM32-based USB to CAN/RS-485/RS-422 adapter

Most USB-to-bus adapters, including tools like CANTact Pro or MeatPi’s Ollie V1 and V2, typically support either CAN or RS-485/RS-422 as fixed-function serial devices. In contrast, the FalCAN Probe by Anders B. Nielsen is a multi-protocol USB adapter based on the STM32F042 microcontroller. The FalCAN Probe is a compact open-source USB Type-C board that connects a computer to CAN, RS-485, and full-duplex RS-422 networks. Instead of using a fixed USB bridge, it exposes the MCU’s native USB interface along with SWD and GPIOs, and can also be used as a small Arm Cortex-M0 development platform. FalCAN Probe specifications: MCU –...
