The first Realtek RTL8157 5Gbps Ethernet to USB 3.2 adapters are now available for $35

WisdPi WP-UT5 is the first Realtek RTL8157 5Gbps Ethernet (5GbE) to USB 3.2 adapter to make it to market, following the launch of Realtek RTL8126 5Gbps Ethernet PCIe and M.2 adapters last June, and the announcement for both the RTL8126 and RTL8157 chips at Computer 2023 last year. While the RTL8126 dongles and cards are fairly cheap at around $16 on average and as low as $12, the WisdPi WP-UT5 is sold at a premium for about $35 on AliExpress, but we can expect the price to down come as more companies introduce 5GbE to USB 3.2 adapters. For reference, the 2.5GbE variants based on RTL8156(BG) can be had for about $20 on Amazon. WisdPi WP-UT5 specifications: Chip – Realtek RTL8157 USB USB 3.2 Type-C female port A-C and C-C cables to support hosts with USB Type-C or Type-A ports Ethernet 10/10/100/2500/5000 Mbps Ethernet Supports 5G Lite (2.5Gbps data rate) […]

Mixtile Edge 2 Kit review with Home Assistant, 2-in-1 Zigbee & Z-Wave mPCIe module

We received the Edge 2 Kit IoT gateway on the Rockchip RK3568-powered Edge2 single board computer (SBC) and a 2-in-1 Zigbee and Z-Wave mPCIe card from Mixtile which we will be reviewing from the perspective of smart home applications using Home Assistant open-source home automation framework. Let’s dive into the details. Unboxing Mixtile Edge 2 Kit CNX Software previously reported on the Mixtile Edge 2 Kit in 2022 and you can check the detailed specifications and block diagram in that earlier article. Since then, Mixtile has found a wider range of applications for the device and is also promoting it as an Edge AI Box that performs AI object detection using the Edge 2 Kit (or the more powerful Mixtile Blade 3) using the built-in NPU (Neural Processing Unit) with up to 1 TOPS of AI performance for tasks such as object detection. Let’s unbox it and take a closer […]

Google Pigweed SDK now supports Raspberry Pi RP2350 microcontroller

Raspberry Pi Pico 2 (RP2350) with Enviro+ pack hat.

Google Pigweed, a collection of open-source libraries for embedded software development, now supports the Raspberry Pi RP2350 MCU and comes as a software development kit (Google Pigweed SDK). These libraries, also called modules, are building blocks that make embedded software development faster and more reliable. It targets tiny 32-bit microcontrollers such as STMicro STM32L452, Nordic Semi nRF52832, and the Raspberry Pi Pico line of microcontrollers. The library components have shipped in Google Pixels, Nest thermostats, robots, satellites, and drones. On August 8, the Pigweed project was released as a software development kit (SDK) in developer preview with official support for Raspberry Pi RP2350 and the associated Pico 2 development board. The new release uses the Bazel build system – a feature upstreamed into the Pico SDK by the Google Pigweed team – and a complete, open-source Clang/LLVM toolchain. The Google Pigweed SDK includes sample code, modules, and a comprehensive tutorial […]

LILYGO T-TWR REV2.1 is an ESP32 walkie-talkie board with display, GNSS, and SA868 module

LILYGO has recently introduced an updated version of their T-TWR ESP32 walkie-talkie development board, the T-TWR REV2.1. This new board not only features Wi-Fi and Bluetooth but also has a GPS module for added functionality. Additionally, it has a new RF front-end matching circuit that can be configured to work with both VHF and UHF frequencies. The board is very versatile and can be programmed with Arduino IDE for various applications. The main difference between the older T-TWR and the newer T-TWR REV2.1 is that the new module has better power management with the AXP2102 single-cell Li-battery PWM charger, allowing it to use USB, a 21700 battery, or an 18650 battery, while the original T-TWR only supports USB and an 18650 battery. The new version also includes a GNSS module along with a microphone-switching matrix and a speaker-switching matrix for better sound quality. Additionally, the REV2.1 has the Push-To-Talk button […]
