Maker Uno RP2040 review with Arduino IDE using micro servo, soil moisture sensor, ultrasonic sensor, and I2C OLED modules

Today, We will review the Cytron Maker Uno RP2040 development board combining the Arduino UNO form factor with the Raspberry Pi RP2040 microcontroller that makes it programmable with the Arduino IDE (C/C++), Micropython, or CircuitPython. The board is suitable for both beginners and advanced users with a convenient port layout that includes a “Maker” connector plus six Grove connectors for sensor modules and a header for four servos besides the Arduino UNO headers. The board offers two power options: USB (5V) via the USB-C connector or a single-cell LiPo/Li-Ion battery via the LiPo connector. Cytron Maker Uno RP2040 specifications SoC – Raspberry Pi RP2040 dual-core Arm Cortex-M0+ processor @ up to 133 MHz with 264 KB SRAM Storage – 2MB flash USB – USB-C port for power and programming Expansion Arduino UNO headers for shields 6x Grove Ports (Digital I/O, PWM Output, UART, I2C, Analog Input) 1x Maker port compatible […]

ODROID-H4+ kit review – Part 1: Unboxing, H4 Type 3 case assembly, and first boot

I’ve just received a kit comprised of an ODROID-H4+ SBC along with a Type 3 enclosure taking up to four 2.5-inch SATA drives and related accessories for review. I’ll start with an unboxing, followed by an assembly guide, and a quick first boot in the first part of the review, before testing performance, features such as IBECC memory, power consumption, and more in the second part of the review. ODROID-H4+ kit unboxing The package I received included small packages for the “H4 Type 3” enclosure and the ODROID-H4 PLUS SBC, a 15V/4A (60W) power supply with US plug adapter, a large fan with screws, as well as four sets of SATA data and power cables. We’ve already provided the ODROID-H4, H4+, and H4 Ultra specifications in the announcement post, but let’s have another quick look at the Intel Processor N97 fanless SBC. The rear panel comes with a DC jack, […]

Review of CrowVi 15.6-inch portable USB-C and HDMI touchscreen display with Windows 11, Ubuntu 24.04, and Raspberry Pi 5

Elecrow CrowVi VF156T – or just CrowVi for shorts – is an ultra-thin 15.6-inch portable touchscreen display with mini HDMI and USB-C input ports making it suitable for a wide range of devices from Windows 11 and Linux mini PCs or laptops, SBCs such as the Raspberry Pi 5, and smartphones featuring a USB-C port with DisplayPort Allt. mode. The display supports 10-point multitouch, offers a 1920×1080 “Full HD” resolution, and includes stereo speakers and a 3.5mm audio jack. Besides the USB-C input, it also comes with an additional USB-C PD port for power in case the host does not provide enough power or only HDMI input is used without the touchscreen function. There’s also a “smart case” acting as a foldable stand on the back so you don’t need to bring your own stand. Elecrow sent us a sample of the CrowVi 15.6-inch portable monitor for review and we […]

GEEKOM XT12 Pro review – Part 3: Ubuntu 24.04 on an Intel Core i9-12900H mini PC

We’ve already looked at GEEKOM XT12 Pro specifications and hardware design in the first part of the review and followed up by reviewing the Intel Core i9-12900 mini PC with Windows 11 Pro in the second part. We’ve now had time to review the GEEKOM XT12 Pro mini PC with the just-released Ubuntu 24.04 operating system to evaluate the compatibility and performance in Linux. In this third and final part of the review, we’ll test features in detail, evaluate performance with benchmarks, test storage and network capabilities, check YouTube video playback at 4K and 8K resolution, perform a stress test to check the cooling solution and provide numbers for fan noise and power consumption of the GEEKOM XT12 Pro mini PC. Ubuntu 24.04 installation and system information We’ve resized the Windows 11 by half in order to install Ubuntu 24.04 in dual boot configuration. After that, we inserted a USB […]

Review of SONOFF SNZB-06P human presence and SNZB-04P door/window Zigbee sensors

SONOFF has been gradually refreshing its Zigbee product lineup since August 2023, and CNX has recently written about the Temperature/Humidity Sensor (SNZB-01P), Switch/Button (SNZB-02P) and Motion Sensor (SNZB-03P), and the SONOFF SNZB-06P human presence sensor. I’ve now had the opportunity to review both the SONOFF SNZB-06P and the new Door/Window Sensor (SNZB-04P). After we keep trying them out for a few weeks, we think reliability is much improved, especially with the Door/Window Sensor, the materials made as well as the appearance look better than the previous models. As for the Human Presence Sensor, it’s the first generation, which is quite impressive considering its price and features. Let’s take a closer look. Door/Window Sensor (SNZB-04P) review Unboxing Obviously, the rounded design differs from the previous rectangular version. It integrates better with the surroundings than the previous model. Additionally, the lithium battery capacity is larger (CR2450 @550mA vs. CR2477 @1000mA), resulting in […]

GEEKOM XT12 Pro review – Part 2: Windows 11 Pro tested on an Intel Core i9-12900H mini PC

GEEKOM XT12 Pro mini PC Review windows 11

We’ve already checked out the specifications, and gone through an unboxing and a teardown of the GEEKOM XT12 Pro mini PC in the first part of the review, so we’ll now report our experience with the 12th Gen Intel Core i9-12900H mini PC with Windows 11 Pro operating system. In this second part of GEEKOM XT12 Pro, we’ll test the features of the Alder Lake mini PC in Windows 11 Pro, run benchmarks, test networking and storage, evaluate cooling performance, and finally provide some numbers for fan noise and power consumption. Software overview and features testing The System->About menu confirms that we have an XT12 Pro mini PC with a 12th Gen Intel Core i9-12900H processor clocked at 2.50 GHz (base frequency) and 32GB RAM that runs Windows 11 Pro operating system version 23H2. The system was tested with Windows 11 OS build 22631.3447. HWiNFO64 program provides more details about […]

Testing ntttcp as an iperf3 alternative in Windows 11 (and Linux)

ntttcp (Windows NT Test TCP) is a network benchmarking utility similar to iperf3 that works in both Windows and Linux written and recommended by Microsoft over iperf3, so we’ll test the alternative in this mini review. iperf3 is a utility of choice for our reviews of single board computers and mini PCs running either Windows or Linux, but we’ve noticed that while Ethernet (up to 2.5GbE) usually performs just as well in Windows and Linux, WiFi is generally much faster in Ubuntu 22.04 than in Windows 11. So when XDA developers noticed a post by Microsoft saying iperf3 should not be used on Windows 11, it caught my attention. Microsoft explains iperf3 should not be used in Windows for three main reasons: The maintainer of iperf – ESnet (Energy Sciences Network) – says “iperf3 is not officially supported on Windows, but iperf2 is. We recommend you use iperf2. Some people […]

“MaUWB_DW3000 with STM32 AT Command” Review – Using Arduino to test UWB range, precision, indoor positioning

Hello, the device I am going to review is the MaUWB_DW3000 with STM32 AT Command. This is an Ultra-wideband (UWB) module from MakerFabs. The core UWB module on this board is the DW3000 UWB transceiver, and it is also equipped with an ESP32 microcontroller programmable with the Arduino IDE, as well as OLED display. The manufacturer claims that this UWB board resolves multiple anchors and tags mutual conflicts and supports up to 8 anchors and 64 tags. Additionally, the manufacturer has added an STM32 microcontroller to handle UWB multiplexing, allowing users to control the core UWB module by simply sending AT commands from an ESP32 microcontroller to the STM32 microcontroller. More information about this UWB board can be found on the manufacturer’s website. “MaUWB_DW3000 with STM32 AT Command” unboxing MakerFabs sent the package to me from China. Inside the package, there were 4 sets of the MaUWB_DW3000 with STM32 AT […]
