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

ntttcp vs iperf3 testbed

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

mauwb dw3000 st tag test

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 […]

Testing Cytron MAKERDISK M.2 NVMe SSDs on Raspberry Pi 5 with GEEKWORM X1001 and Waveshare M.2 PCIe HAT+

MAKERDISK M.2 NVMe SSD Raspberry Pi 5 review

Cytron has sent us a few of their MAKERDISK NVMe SSDs preloaded with Raspberry Pi OS so that we can test them on a Raspberry Pi 5 SBC, either with a GEEKWORM X1001 or Waveshare M.2 PCIe HAT+ add-on boards both of which were also provided by the company. Ever since the first M.2 PCIe HATs for the Raspberry Pi 5 were released, we knew Raspberry Pi Limited was working on its own model, and based on some Twitter/X “rumors” (with photos) the launch of the official M.2 HAT+ should be just around the corner. So it’s the perfect timing to test some SSDs on the Raspberry Pi 5 even though I’ve yet to get the official HAT+ Cytron “MAKERDISK” package unboxing The Malaysian company sent me a kit with everything I needed to get started, minus the Raspberry Pi 5 I already owned. This includes 128GB or 256GB NVMe […]

HUION Kamvas Pro 16 2.5K drawing tablet review

HUION Kamvas Pro 16 (2.5K) is a 15.8-inch drawing tablet with 2.5K resolution that comes with a stylus supporting 8192 levels of pressure. The company sent us a review sample, so I’ll test it as an external display in Windows 11 and Ubuntu 22.04, and check the drawing functions of the Kamvas Pro 16 with the stylus as well as other potential use cases. Kamvas Pro 16 (2.5K) specifications (model GT1602) But before that, let’s list the specifications of the display: Panel – 15.8-inch (diagonal) IPS display at 60 Hz Resolution – 2560 x 1440 (16:9) QHD PPI (Pixels Per Inch) – 186 Active Area – 349.6 x 196.7 mm Contrast Ratio – 1200:1 Brightness – 220nit (Max.)

Review of Purple Pi OH – A Rockchip RK3566 SBC tested in 2GB/16GB and 4GB/32GB configurations

Review of Purple Pi OH and Purple Pi OH Pro

Hello, I am going to review the Purple Pi OH boards from Wireless-Tag. The Purple Pi OH is a single-board computer (SBC) mechanically compatible with the Raspberry Pi. They are designed for personal mobile Internet devices and AIoT devices, which can be used in various applications, such as tablets, speakers with screens, and lightweight AI applications. The manufacturer sent me two models. The first model is the Purple Pi OH, which is equipped with 2GB of memory and 16GB of storage space and supports 2.4GHz Wi-Fi. The second model is the Purple Pi OH Pro, equipped with 4GB of memory and 32GB of storage space. This board supports both 2.4GHz and 5GHz Wi-Fi. The other components of both devices are almost the same. They are powered by the Rockchip RK3566 chip, which integrates a quad-core Cortex-A55 processor up to 1.8 GHz, a Mali-G52 GPU from Arm for 3D graphics acceleration, […]

SONOFF POW Ring Review – A WiFi CT Clamp power meter tested with eWelink and Home Assistant

SONOFF POW Ring review

The trend of measuring the energy usage of household electrical devices has become increasingly popular among Smart Home users in the past few years. We have received the new SONOFF POW Ring Smart Power Meter Switch device for review from ITEAD. Unlike SONOFF’s existing energy monitoring devices such as POW Elite, SPM, DualR3, POW3, and POW Origin, this new device, also called POWCT, utilizes a current transformer (CT) to measure the current flow, or total power being consumed. This method provides no physical contact with live wires and reduces the risk during installation. Additionally, it can measure currents of up to 100A, which is significantly higher than previous models. This makes it suitable for measuring electricity usage at the main circuit breaker, energy generated from solar panels, or even for Electric Vehicle (EV) home chargers. The SONOFF POW Ring, which we are testing today, is not only a Smart Power […]

MINIX Z100-0dB review – Part 3: A fanless Intel N100 mini PC tested with Ubuntu 22.04

MINIX Z100-0dB review Ubuntu 22.04 Linux

After the first part of the review with an unboxing and a teardown of the MINIX NEO Z100-0dB mini PC, we tested the fanless Intel N100 mini PC with Windows 11 Pro in the second part, and we are now ready to report our experience with Linux, and more specifically Ubuntu 22.04, on the MINIX Z100-0dB mini PC in the final and third part of the review. We will go through features testing, run some benchmarks to evaluate the performance in Linux, perform storage and network performance tests, check the cooling ability of the mini with a stress test, and also check its power consumption under different scenarios. We will also compare the MINIX Z100-0dB to the actively cooled GEEKOM Mini Air12 mini PC that uses the same Intel Processor N100 CPU. Ubuntu 22.04 installation We will install Ubuntu 22.04 alongside Windows 11 Pro in dual boot configuration, so we […]
