RT-Thread Vision board review – Part 1: OpenMV on Renesas RA8D1 Cortex-M85 microcontroller

RT-Thread VIsion board vs WeAct STM32H743

I am always interested in real-time operating systems (RTOS) for microcontrollers (MCUs) with my past backgrounds in µC/OS-II, mbed, and FreeRTOS. When the opportunity arose to get my hands on the RT-Thread Vision Board, thanks to the RT-Thread team and CNX Software, I was excited to check it out. This board, a collaboration between RT-Thread and Renesas, packs a powerful Renesas RA8D1 Cortex-M85 MCU and comes pre-loaded with OpenMV firmware. OpenMV’s MicroPython engine lets you jump right into embedded vision development, perfect for experimenting with computer vision tasks. But the real power lies in RT-Thread’s ability to handle tasks very quickly, which we’ll explore with C/C++ development in part two. This first part will focus on getting you familiar with the hardware using the OpenMV firmware, making it a smooth entry point for beginners. Plus, I have a collection of other Renesas evaluation boards, so you can bet I’ll be […]

SONOFF Zigbee Bridge Ultra Review – eWelink app, Matter Bridge, Turbo Mode for extended range, and Home Assistant

SONOFF Zigbee Bridge Ultra Review

We have received two more Zigbee smart home products from ITEAD to review. It appears that SONOFF has strategically introduced a variety of Zigbee devices in the first half of this year. The first one we will be reviewing is the SONOFF Zigbee Bridge Ultra, which we believe will eventually replace the Zigbee Bridge (2020) and Zigbee Bridge Pro (2022) and comes with additional features, such as being a Matter Bridge. The second device we’ve received is the SONOFF Micro Zigbee USB Adapter for which we’ll post a review in the next few days, But first, let’s dive into the SONOFF Zigbee Bridge Ultra review. Overview SONOFF Zigbee Bridge Ultra (Ultra for short and also called SONOFF ZBBridge-U) is a multi-functional device. Compared to its predecessor, the Zigbee Bridge Pro, the Ultra shows big improvements in features and hardware specs. It boasts a much more powerful chip (Rockship RV1109 vs. […]

LattePanda Mu review – Part 1: an Intel N100 Compute Module tested with Windows 11, carrier boards with PCIe slots

LattePanda Mu Full Carrier Windows 11 Review

Last April, DFRobot launched the LattePanda Mu x86 Compute Module powered by an Intel N100 Alder-Lake processor with 8GB RAM and a 64GB eMMC flash along with Lite and Full function carrier boards for evaluation. End customers will typically design their own carrier board without having to take of high-speed signals for the LPDDR5 memory and other complexities during the PCB layout. DFRobot has sent us the LattePanda Mu module for review along with the Lite and Full Function carrier boards, a heatsink for passive cooling, and an active cooler so we can compare both cooling solutions.  Let’s have a look at the LattePanda Mu module and accessories before testing the kit with the Windows 11 operating system, including the PCIe x4 slot. LattePanda Mu kit unboxing The parcel included three retail boxes. The smallest box housed the LattePanda Mu Compute Module, a heatsink, and an active cooler. The second […]
