How I “fixed” the display on Lichee Console 4A terminal

How to fix Lichee Console 4A display

When I wrote a hands-on post about Lichee Console 4A RISC-V development terminal I noted the display would sometimes have strange effects or simply go black. I’ve now fixed the issue, and I was just probably unlucky since the issue must be rare, but I’ll still document it in case somebody encounters a similar problem and for fun! First, the video below shows what I would see on my terminal after using it for a few minutes. Since then, the display has gone completely dark, and all I see is the backlight, but I can still access the device through an SSH terminal. It looks like a bad connection issue, but I still contacted Sipeed and they told me it must have been the display connector. So I turned off the device and reopened the enclosure to remove and reinsert the cable for the display as shown in the photo […]

Chatreey AM08 Pro review – Part 3: Ubuntu 22.04 and ESXi 7.0 on an AMD Ryzen 9 7940HS mini PC

Chatreey AM08 Pro Review Ubuntu VMWare ESXi

In the first article, I checked out the hardware of the Chatreey AM08 Pro mini PC powered by an AMD Ryzen 9 7940HS CPU and tested it with Windows 11 Pro in the second part of the review. Now it’s time for the third part where I’ll test Ubuntu 22.04.03 Desktop OS and ESXi 7.0 update 3C hypervisor on the AM8 Pro mini PC. The installation process was simple enough and both WiFi and Ethernet were detected correctly.

MINIX NEO Z100-0dB fanless N100 mini PC review – Part 1: Unboxing, teardown, and first boot

MINIX Z100-0dB mini PC review

MINIX Z100-0dB (or MINIX NEO Z100-0dB) is a fanless mini PC powered by the popular Intel Processor N100 quad-core Alder Lake-N CPU with up to 32GB RAM, up to 512GB M.2 SSD, various USB 3.2/2.0 ports, a microSD card slot, two HDMI 2.0 ports, and a 2.5GbE RJ45 jack, as well as WiFi 6 and Bluetooth 5.2 wireless module. MINIX sent us a sample of the NEO Z100-0dB mini PC for review with 16GB DDR4-3200 RAM and a 512GB M.2 SSD preloaded with Windows 11 Pro. Since we’ve already listed the specifications in the announcement, today, we’ll go through an unboxing and a teardown before giving it a quick try booting Windows 11 Pro. We will then test the performance and features of the mini PC in detail with  Windows 11 Pro and Ubuntu 22.04 (or 24.04) in the next parts of the review in several weeks.   MINIX NEO […]

OpenWrt One/AP-24.XY is an upcoming router board developed by OpenWrt and Banana Pi

OpenWrt One AP-24.XY

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

Reolink Argus PT Ultra Solar Panel Instllation

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 Nano Matter Silicon Labs

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 […]
