Beelink SEI Review – A Core i3-10110U Mini PC Tested with Windows and Ubuntu

Beelink has launched a new range of mini PCs called the SEi Series. Similar in size and appearance to an Intel ‘NUC’ they are available in various configurations. Beelink sent a Core i3-10110U SEi model for review which is the version that has now replaced their i3-1005G1 model which they had to discontinue due to the lack of processor availability. There is also an i5-8259U model in the series. Beelink SEi Hardware Overview The SEi physically consists of a 124 x 113 x 41mm (4.88 x 4.48 x 1.61 inches) rectangular plastic case. It is an actively cooled mini PC and uses Intel’s 14 nm++ Core i3-10110U Comet Lake processor which is a dual-core 4-thread 2.10 GHz processor boosting to 4.10 GHz with Intel’s UHD Graphics for 10th Gen Intel Processors. The front panel has a power button, a headphone jack, a Type-C USB 3.0 port, and two USB 3.0 […]

A closer look at Raspberry Pi RP2040 Programmable IOs (PIO)

The popularity of Raspberry Pico board powered by RP2040 microcontroller has made every reader wanting to know more about the board and chip. So today we will be talking about RP2040’s Programmable IOs, a feature that makes it different from most other microcontroller boards. The two PIO blocks or let’s call it the hardware interfaces in the RP2040 have four state machines each. These two PIO blocks can simultaneously execute programs to manipulate GPIOs and transfer raw data. Now, what do these state machines do? Well, the PIO state machines execute the programs fetched from various sources. Sometimes the programs are taken from the PIO library (UART, SPI, or I2C) or user software. Why Programmable I/O? All the boards usually come with hardware support for digital communications protocols such as I2C, SPI, and UART. However, if you plan to use more of these interfaces than what is available on the […]

Getting Started with Raspberry Pi Pico using MicroPython and C

Raspberry Pi Pico board was just launched last Thursday, but thanks to Cytron I received a sample a few hours after the announcement, and I’ve now had time to play with the board using MicroPython and C programming language. I went to the official documentation to get started, but I had to look around to achieve what I wanted to do, namely blinking some LEDs, so I’ll document my experience with my own getting started guide for Raspberry Pi Pico using a computer running Ubuntu 20.04 operating system. The instructions will be similar for Windows and Mac OS. Preparing the hardware In theory, we could just get started with the board alone, but since I got some headers with my board, I also took the opportunity to try out Pine64 Pinecil soldering iron powered by MINIX NEO P2 USB-C power supply. The soldering iron worked great for about one minute, […]

Cybovac S31 Review – A smart robot vacuum cleaner with visual SLAM support

I’ve been asked to review robot vacuum cleaners in the past but refused because they were quite basic with a simple vacuum function, obstacle detection, maybe a mopping function, and not much else. But Kyvol Cybovac S31 is different as it integrates a laser distance sensor (LDS) enabling visual SLAM to create a map of your house, and can be controlled with a mobile app for Android or iOS which ended up even more useful than I initially expected. S31 Smart Robot Vacuum Cleaner Unboxing The package was much bigger than I expected, mostly because the charging station also includes a dust bag where dust from the main unit is automatically vacuumed each time cleaning is complete. Key features of the system as shown above: LDS robot vacuum cleaner (main unit) 4 levels of suction power Cleaning modes – Auto, area, spot, edge Anti-drop and anti-collision features 2.4 GHz WiFi […]

H2 Net Card adds four 2.5 GbE ports to ODROID-H2/H2+ SBC

ODROID-H2+ is already a cool single board computer with an Intel Gemini Lake Refresh processor, up to 32GB RAM, dual 2.5GbE networking, support for SATA and NVMe storage, dual 4K video output, and more. But in recent days, I’ve read people complaining recently announced WiFI 6 or WiFi 6E routers only had one 2.5 Gbps or 5 Gbps Ethernet jack and wanted all/more RJ45 connectors to be 2.5 GbE ports or greater. But if even the two 2.5GbE ports on ODROID-H2+ are not quite enough for your needs, Hardkernel H2 Net Card triples that amount by adding four extra 2.5 GbE to the x86 SBC. It also works on ODROID-H2, meaning you’d get the existing dual Gigabit Ethernet ports, plus the four 2.5GbE ports from the M.2 card. There’s no much in the way of specifications for H2 Net Card: 4x Ethernet ports up to 2.5 GbE via RTL8125 controller. […]

Pine64 mailbag – PinePhone postmarketOS Edition, PineCone BL602 board, and Pinecil soldering iron

Pine64 community was pretty busy last year with the launch of several products. Recently I’ve received a couple of packages with some of those products, namely PinePhone Community Edition: PostmarketOS, PineCone WiFi & BLE IoT board based on BL602 RISC-V SoC, and Pinecil soldering iron also based on a RISC-V chip for control, but this time GD32V generic-purpose MCU. I’ll most show what I have received without going into too many details, except for PinePhone which I have already set up and used for one hour or so. PineCone BL602 board I received PineCone at the end of last year in a separate envelope with the board only. There’s not much to it with the BL602 processor offering WiFI and Bluetooth, a USB-C port for programming and power, and a few I/Os. The board is interesting as it is the first RISC-V IoT board with wireless connectivity built into the […]

Sainsmart Genmitsu 4030 review – Unboxing, mods, and first cuts

Karl here. This will be a long one but I haven’t had this much fun with a product review in quite some time. I don’t consider myself a complete noob with CNC routers but I have only scratched the surface. Learning new things really drives me and being able to make more permanent things is very satisfying. I have some experience with the Sainsmart 3018 CNC router. I had a lot of fun with it but the build volume was on the smaller side so really limited on what can be done with it. I still recommend it as a starter CNC router and as a good stepping stone to get your feet wet and the Genmistu PROVerXL4030 as the next step. I was able to make some cool things with the 3018 and I hope now to take it to the next level with the Genmistu 4030. Before we […]

Rock Pi X Review – An Atom x5 SBC running Windows 10 or Ubuntu 20.04

The ROCK Pi X is the first x86 SBC (single board computer) from Radxa and resulted from repeated enquiries about running Windows on their earlier ROCK Pi 4. The ROCK Pi X comes in two models (Model A and Model B) with each model having either 1GB, 2GB, or 4GB of RAM and either 16GB, 32GB, 64GB, or 128GB of eMMC storage. Additionally, the Model B includes WiFi and Bluetooth together with supporting Power over Ethernet (PoE) although this requires an additional HAT. Both Seeed Studio and Radxa provided samples and in this review, I’ll cover some performance metrics from both Windows and Ubuntu and also discuss the thermals. Rock Pi X Hardware Overview The ROCK Pi X is similar in size to a Raspberry Pi board… but with slightly different ports and port locations even when compared to the Raspberry Pi 4. It is physically slightly larger than its […]
