Smart Home News – ESPHome 2025.2.0 Firmware, Home Assistant gets Matter certified, and (some) ChromeCast devices hit troubles

Smart Home news ESPHome Firmware Home Assistant Matter ChromeCast

When I wrote about the Home Assistant 2025.3 release last week, it was pointed out to me that ESPHome firmware had its own release on February 19th, and in other Smart Home news, Home Assistant got Matter certified, and some ChromeCast devices temporarily stopped working which impacted video/audio streaming and integration with Google Home. Let’s have a quick look at all three pieces of news. ESPHome 2025.2.0 firmware ESPHome 2025.2.0 was released on February 19  implements audio components improvements with support for new components/hardware for better support of Espressif’s S3-Box products,  new speaker components for advanced functionality when using Voice Assistant, a new speaker media player component for announcements and music streams, and a mixer speaker component to combine the two streams. The new release also supports alpha-blending images when using LVGL, and the Online Image Component was updated to add support for both BMP and JPEG image formats. It […]

Sapphire Edge+ VPR-5050 “AMD Embedded+” mini-ITX motherboard combines AMD Ryzen V2748 CPU and Versal AI Edge VE2302 SoC FPGA

Sapphire EDGE+ VPR-5050-MB

Right in time for Embedded World 2025, Sapphire Technology has introduced the Edge+ VPR-5050 “AMD Embedded+” mini-ITX motherboard with AMD Ryzen V2748 octa-core CPU, and AMD Versal AI Edge VE2302 adaptive SoC that combines Cortex-A72 hard core with FPGA fabric. It’s an update to last year’s VPR-4616-MB mini-ITX motherboard with the same Versal VE2302 adaptive SoC, but a lower end AMD Ryzen R2314 quad-core processor. Two versions of the Edge+ VPR-5050 are available: the VPR-5050-MB and VPR-5050A-MB with the only obvious difference from the specifications being a 64GB eMMC flash on the “A” model, and the different RAM capacities (2x 4GB LPDDR4 vs 2x 8GB LPDDR4). Sapphire Edge+ VPR-5050 specifications: AMD Embedded+ Architecture Adaptive SoC Subsystem Main IC – AMD Versal AI Edge VE2302 with dual Arm Cortex-A72 core processor @ up to 1.6 GHz, dual-core Arm Cortex-R5F, 23 TOPS AI engine, FPGA fabric, etc… System Memory VPR-5050-MB – 2x […]

Review of SunFounder 10.1-inch touchscreen display for SBCs using Raspberry Pi 5 and Radxa ROCK 5B

SunFounder 10.1-inch RPI Touchscreen Display Review

SunFounder has just sent us one of their 10.1-inch touchscreen display designed for single board computers (SBCs) for review. It supports the Raspberry Pi family, but not only, thanks to a flexible design that allows mounting all sorts of boards with mounting holes that fit within an 85x70mm area. All you need is a board with HDMI output, a spare USB port for the touchscreen, and 5V USB-C input (up to 5A). So I’ll first test the SunFounder 10.1-inch touchscreen display with a Raspberry Pi 5 (85x56mm), then a larger Radxa ROCK 5 Model B Pico-ITX SBC (100 x 72mm). Since the display can also be used as an external touchscreen monitor, I’ll also try it with my laptop in Ubuntu 24.04 and Windows 11. SunFounder 10.1-inch touchscreen display specifications Key features and specifications: Display Type – IPS LCD Resolution – 1280×800 (16:10 aspect ratio) Touchscreen – 10-point capacitive Viewing […]

Hidden proprietary Bluetooth HCI commands in ESP32 microcontroller could pose a security risk

ESP32 HCI commands backdoor

Security is hard. Just as Espressif Systems announced PSA Level 2 for the ESP32-C6 microcontroller, Spain-based cybersecurity company Tarlogic published their findings about a hidden Bluetooth functionality that can be used as a backdoor in the previous generation ESP32, and gave a presentation in Spanish at Rootedcon 2025. Specifically, they found hidden proprietary Bluetooth HCI (Host Controller Interface) commands used to read & write controller memory, and typically used for debugging. However, they could also facilitate supply chain attacks, the concealment of backdoors in the chipset, or the execution of more sophisticated attacks. Tarlogic initially called it a “backdoor”, but some disputed the claim (more on that later), and the company eventually issued an update downgrading it to a “hidden” feature: We would like to clarify that it is more appropriate to refer to the presence of proprietary HCI commands—which allow operations such as reading and modifying memory in the […]

UP Squared 7100 Review – Part 2: An Intel N100 fanless SBC preloaded with Ubuntu Pro 24.04

UP Squared 7100 Ubuntu Pro 24.04 Review

I’ve already checked out the hardware of the UP Squared 7100 fanless SBC in the first part of the review with an unboxing and first boot to Ubuntu Pro 24.04. I’ve now had time to test the features of the Intel N100 SBC with Ubuntu Pro, so I’ll report my experience with the system in this second part of the review.

I’ll report my experience with Ubuntu Pro features, test hardware features of the board including GPIOs, check out BIOS options, run a few benchmarks, and measurement power consumption.

Orange Pi RV2 – A $30+ RISC-V SBC powered by Ky X1 octa-core SoC with a 2 TOPS AI accelerator

Orange Pi RV2

While the Orange Pi RV RISC-V SBC introduced at the Orange Pi Developer Conference 2024 last year is yet to be launched (should be up in a few days), the company has just launched the Orange Pi RV2 powered by the Ky X1 octa-core RISC-V SoC with a 2 TOPS AI accelerator, up to 8GB LPDD4X, optional eMMC flash moduyle, two M.2 sockets for storeage, dual gigabit Ethernet, WiFi 5, and more. While RISC-V has made a lot of progress over the years, Linux RISC-V SBCs were often synonymous with relatively expensive hardware for developers, since software is often unsuitable for production, at least for applications using graphics. The Orange Pi RV2 addresses the cost issue since the octa-core RISC-V SBC sells for just $30 to $49.90 depending on the configuration. Orange Pi RV2 specifications: SoC – Ky X1 CPU – 8-core 64-bit RISC-V processor GPU – Not mentioned VPU […]

Posted on by Jean-Luc Aufranc (CNXSoft) - No Comments on ESP32-C6 is the first RISC-V microcontroller to achieve PSA Level 2 security compliance

ESP32-C6 is the first RISC-V microcontroller to achieve PSA Level 2 security compliance

ESP32-C6 RISC-V MCU PSA Level 2 Certified

Arm introduced the Platform Security Architecture (PSA) back in 2017 to make Internet of Things (IoT) chips more secure. Since then we’ve seen many PSA certified products such as Silicon Labs’  EFR32FG23 (FG23) and EFR32ZG23 (ZG23) Cortex-M33 microcontrollers with PSA Level 3 certification. But as announced in 2017, PSA is architecture-agnostic, and the security architecture has gone beyond just certifying Arm microcontrollers, as shown by Espressif Systems who just announced that the ESP32-C6 RISC-V wireless microcontroller was now PSA Level 2 certified. The ESP32-C3 RISC-V MCU also achieved PSA certification earlier, but at the lower Level 1. The PSA-L2 certification was mostly made possible thanks to the ESP-TEE (Trusted Execution Environment) firmware that provides hardware-enforced isolation to enhance security for operations such as cryptographic key management, secure boot verification, and firmware updates. Espressif also reminded us of ESP32-C6’s hardware security features in the announcement: Physical Memory Protection (PMP) and Access […]
