OpenWrt developers have started the process to develop the “OpenWrt One/AP-24.XY” router board based on MediaTek MT7981B (Filogic 820) SoC and MediaTek MT7976C dual-band WiFi 6 chipset, and designed in collaboration with Banana Pi that will also handle manufacturing and distribution of the router board. As of the OpenWrt 23.05 release, close to 1,800 routers and other devices are officially supported by the lightweight embedded Linux operating system, and many more claim to be running OpenWrt through a fork of the OS. But none of those are made by OpenWrt developers who have now decided to create their own router board in collaboration with Banana Pi since they’ve done such boards including the BPI-R4 WiFi 7 router SBC. OpenWrt One/AP-24.XY preliminary specifications: SoC – MediaTek MT7981B (Filogic 820) dual-core Cortex-A53 processor @ 1.3 GHz System Memory – 1GB DDR4 Storage 128 MB SPI NAND flash for U-boot and Linux 4 […]
Reolink Argus PT Ultra review – A solar powered 4K WiFi Pan-and-Tilt smart security camera
Nearly four years ago, I reviewed the solar-powered Reolink Argus PT pan-and-tilt security camera. The device worked (and still works) mostly fine, but it was at a time when security cameras did not implement AI features like people and vehicle detection just yet relying only on PIR motion sensors so I’d get plenty of false positives. The WiFi connection is not overly reliable either especially when I tried to access the camera from outside my house, something that does not happen with the PoE and 4G LTE models from the company. Reolink asked me whether I wanted to review the new Reolink Argus PT Ultra security camera with higher 4K resolution, dual-band WiFi support, as well as people, vehicle, and pet detection, and most of the same other features found on the older Argus PT. So I took up on the offer and I’ve used it for about one month […]
Arduino and Silicon Labs collaborate to bring Matter to Arduino boards and IDE
Arduino and Silicon Labs have joined hands to both bring Matter-compatible SiLabs wireless microcontrollers to the Arduino IDE and then design an upcoming Arduino Nano based on SiLabs MGM240 Arm Cortex-M33 microcontroller with Matter, Thread, Zigbee, and Bluetooth LE protocols. Available now: Arduino Core for Silicon Labs devices The first phase of the collaboration involves getting Arduino core for Silicon Labs development boards so that compatible devices can be programmed in the IDE. The good news is that it’s available now and works with four existing wireless boards: SparkFun Thing Plus Matter MGM240P based on MGM240PB32VNA Arm Cortex-M33 MCU with Matter, Thread, Zigbee 3.0, and Bluetooth 5.3 LE connectivity SiLabs xG27 Dev Kit based on EFR32BG27C140F768IM40 Arm Cortex-M33 MCU with Bluetooth LE 5.3, Bluetooth Mesh, Proprietary 2.4 GHz connectivity SiLabs xG24 Explorer Kit based on EFR32MG24B210F1536IM48 Arm Cortex-M33 MCU with Bluetooth 5.3 LE, Bluetooth Mesh, Matter, OpenThread, Zigbee, Proprietary 2.4 […]

SunFounder PiCar-X 2.0 review – A Raspberry Pi 4 AI robot car programmable with Blockly or Python
SunFounder PiCar-X 2.0 is an AI-powered self-driving robot car using the Raspberry Pi 3/4 as the main processing board. It is equipped with a camera module that can be moved by a 2-axis servo motor, allowing the camera to pan or tilt, an ultrasonic module for detecting distant objects, and a line detection module. The PiCar-X robot can also perform computer vision tasks such as color detection, face detection, traffic signs detection, automatic obstacle avoidance, and automatic line tracking. The PiCar-X can be programmed with two computer languages: Blockly-based Ezblock Studio drag-and-drop program and Python, and the robot works with OpenCV computer vision library and TensorFlow for AI workloads. Finally, you can also control the robot through the SunFounder controller application on your mobile phone. The company sent us a sample of the Picar-X 2.0 for review, so let’s get started. SunFounder PiCar-X 2.0 robot overview The PiCar-X robot kit […]
Lichee Console 4A portable RISC-V development terminal review – Part 1: Unboxing, teardown, and hands on
Sipeed has just sent me a “Lichee Console 4A portable RISC-V development terminal” for review. It’s a quad-core RISC-V mini laptop based on the Alibaba T-Head TH1520 processor with a 7-inch touchscreen display, and my model is equipped with a Lichee LM4A module fitted with 16GB RAM and 128GB eMMC flash. I’ll start the review of the RISC-V developer kit with an unboxing, a teardown, and a quick try with the preinstalled Debian 12 “Bookworm” image, before testing the latter in the second part of the review. The second part will take some time as we have about twenty reviews planned for now, four of which I’ll be taking care of myself… Lichee Console 4A unboxing I received the device in a package indicating I had been sent the 16GB+128GB model and reading “Lichee Console 4A portable RISC-V developer terminal” which makes it clear it’s based on RISC-V, is portable […]
Emporia Vue Gen 2 energy monitor ships with 16 CT clamps, supports single and three-phase power
We’ve just written about the “Smart Powermeter” measuring the power consumption of AC appliances through six CT clamps and running either ESPHome or Arduino firmware on ESP32-S3 WiFi and Bluetooth microcontroller. Some people asked about tri-phase and having more CT clamps. One of the commenters then recommended readers to look at the Emporia Vue energy monitor that ships with 16 CT clamps for individual devices/rooms, two 200A CT clamps for whole house monitoring, and supports single-phase up to 240VAC line-neutral, single, split-phase 120/240VAC, and three-phase up to 415Y/240VAC (no Delta). So let’s do that now. Emporia Vue Gen 2 specifications: Connectivity – 2.4 GHz WiFi 4 Probes 2x 200A current sensors for service mains; 3.5mm plug; dimensions: 65 x 44 x 41mm 16x 50A current sensors to individually monitor air conditioner, furnace, water heater, washer, dryer, range, etc; 2.5mm plug, dimensions: 41 x 23 x 26; accurate from ±2% […]
ASRock Industrial upgrades mini-ITX, micro-ATX, and ATX motherboards for Intel Core 14th Gen Raptor Lake-S Refresh processors
ASRock Industrial has just announced 25 (twenty-five!) industrial motherboards powered by 14th gen Intel Core Raptor Lake-S Refresh hybrid processors with up to 24 cores and 32 threads introduced last October, and supporting up to 96GB DDR5 4800/5600 memory. The thin and high-rise mini-ITX, micro-ATX, and ATX industrial motherboards support up to four 4K displays, PCIe Gen5 interfaces, up to three 2.5GbE ports (and 10GbE LAN for the IMB-X1316-10G model), and USB 3.2 Gen2x2 (20 Gbps) ports for factory automation, robotics, machine vision, smart retail, kiosks, digital signage, gaming, security, and more. I would usually list the specifications of the motherboards, but since we have 25 different models, I’ll skip that and provide a summary. One reason ASRock Industrial has so many models is that those are existing motherboards with socketed processors and the company offered 12th and 13th gen CPUs so far, and the company simply updated the BIOS […]
