GAOMON PD2200 pen display review – A 21.5-inch drawing tablet tested with Windows 11, Ubuntu 24.04, Krita software

Today, we’ll review the GAOMON PD2200 pen display, a 21.5-inch drawing tablet with 1920 x 1080 resolution, and an AP32 stylus with 8192 levels of pressure sensitivity. It allows you to draw and write in the same way as you would with a pen and paper. It can also be used as a standard HDMI monitor and is similar to the smaller, but higher resolution (2560 x 1440) HUION Kamvas Pro 16 (2.5K) we reviewed last April. HUION and GAOMON are different brands, but based on the shipping information, they may be made by the same company… Guangdong Gaomon Technology sent us a sample of the GAOMON PD2200 drawing tablet for review. We will test the device as an external display in Windows 11 and Ubuntu 22.04 and as a drawing tablet using the stylus with Krita open-source software that works fine in both Windows and Linux. GAOMON PD2200 Pen […]

Using RISC-V cores on the Raspberry Pi Pico 2 board and RP2350 MCU – From blinking an LED to building Linux

Raspberry Pi Pico 2 RP2350 RISC-V review

Raspberry Pi Pico 2 was released last month with a Raspberry Pi RP2350 microcontroller equipped with two Arm Cortex-M33 cores and two 32-bit RISC-V “Hazard3” cores with up to two cores usable at any time. So in this guide, we’ll show how to use the RISC-V cores on the RP2350 MCU, compare their performance against the Arm Cortex-M33 cores, and even build Linux for RISC-V for RP2350 boards that have PSRAM. Apart from the extra memory and more powerful cores, plus new features related to security and the HSTX interface, the Raspberry Pi Pico 2 and Pico will be very similar to the end user and the instructions in our article “Getting Started with Raspberry Pi Pico using MicroPython and C” remain valid. I don’t think there’s a MicroPython RISC-V image yet, so we’ll focus on running C programs on the RISC-V cores. A quick check with the Arm cores […]

Comparison of Raspberry Pi 5 with 2GB and 8GB RAM – Hardware, benchmarks, and power consumption

The Raspberry Pi 5 with 2GB RAM was launched last week, and since I got a sample for review, I decided to compare it to the Raspberry Pi 5 with 8GB RAM to see if I could find any noticeable differences between the two boards. I’ll start with a visual inspection to show differences on the PCBA, then check system information, run some benchmarks, check power consumption, and finally try to open as many tabs in Firefox until the 2GB RAM is filled and the system becomes unusable. Raspberry Pi 5 2GB vs Raspberry Pi 8GB – visual inspection We should first have a quick look at the boards and packages there’s no obvious difference apart from seeing 2GB RAM and 8GB RAM on the respective packages. But if we look closer, we can see the resistors for memory capacity detection are in different locations for “2G” and “8G”, and […]

Review of Napcat wireless NVR with solar-powered security cameras

Napcat solar-powered wireless NVR review

After I reviewed the NapCat smart video doorbell last June, the company asked me to review a wireless NVR with solar-powered security cameras and I understood I would receive a kit with four solar-powered cameras and an NVR with storage preinstalled. In this review, I’ll go through an unboxing, a quick teardown of the NVR, the installation process, and my experience with the Napcat NVR user interfaces (connected to HDMI) and the Napcat Life Android app which I also used with the video doorbell. Napcat wireless NVR N1S22 kit unboxing The package I’ve received reads “N1S22” model of a “Solar-powered Security Camera System” and is quite smaller than I expected. One reason for the small size is that my kit only comes with two cameras instead of four, and the company also did a good job of making everything take as little space as possible. On the net, you’ll see […]

Radxa X4 SBC kit review – Part 1: Unboxing, case assembly, Ubuntu 24.04 installation

The Radxa X4 is a single-board computer that uses an Intel N100 processor instead of an Arm-based SoC found in most SBCs and also embeds a Raspberry Pi RP2040 microcontroller for GPIO control. What’s interesting is that the Radxa X4 is a small computer board with a similar form factor as the Raspberry Pi 5 SBC, but benefits from the higher performance of Intel “Alder Lake-N” Processor N100 CPU and out-of-the-box compatibility with most operating systems, except for specific features such as GPIOs. The Intel N100 board also comes with a built-in M.2 M-key socket (so no need for an extra HAT) that supports higher speed storage thanks to a PCIe 3.0 x4 interfaces, as well as WiFi 6 connectivity, making the Radxa X4 an interesting option for those looking for a small, capable computer board for home, IoT, or industrial use. The company sent us a full kit with […]

Radxa ROCK 5 ITX RK3588 mini-ITX motherboard review – Building an Arm PC and NAS with Debian KDE

ROCK 5 ITX Review: Build Arm Computer NAS

In this review, I’ll show how I installed Debian on the ROCK 5 ITX mini-ITX motherboard powered by a Rockchip RK3588 octa-core Arm Cortex-A76/A55 processor, before building a computer/NAS with the Arm mini-ITX motherboard, testing various features and running benchmarks. In the first part of the review, we checked out the Radxa ROCK 5 ITX (Arm) and Jupiter (RISC-V) mini-ITX motherboards with specifications and unboxing, and the Auriga 6-Bay NAS mini-ITX chassis used in this review. I already built the computer with the Jupiter RISC-V mini-ITX motherboard, so here I simply switched the RISC-V motherboard with the Radxa ROCK 5 ITX Arm motherboard and installed a few SATA drives. Radxa ROCK 5 ITX first boot – A tricky start… Radxa provides getting started instructions on the documentation website which I mostly follow to hopefully boot within a few minutes. I had to prepare the hardware first. So I installed a […]

CrowView Note Review – A 14-inch laptop shell designed for Raspberry Pi 5 and Jetson Nano Developer kit

Elecrow CrowView Note is a laptop shell with a 14-inch Full HD display, an 84-key QWERTY keyboard with a touchpad, built-in speakers and microphone, and a 5,000 mAh battery that’s specially designed for the Raspberry Pi 5 and the Jetson Nano Developer Kit thanks to adapters. However, it can be used with any machine with either a full-featured USB-C port or spare USB and HDMI ports. So it works with any Raspberry Pi model, Windows, Mac OS, or Linux computers, Android smartphones, PS4/PS5 game consoles, and more. This type of laptop shell has been around for years with the first one being the Laptop shell for the Motorola Atrix 4G smartphone introduced in 2011, and more recently Nexdock launched a range of laptop shells such as the Neckdock XL 15.6-inch touchscreen display and wireless charging. The CrowView Note differentiates itself with its low price and direct compatibility with the Raspberry […]

Twotrees SK1 3D printer review – Part 2: Enclosure kit and AI camera

Twotrees SK1 Enclosure Kit AI camera review

We reviewed the Twotrees SK1 CoreXY 3D printer capable of delivering high printing speeds last March, but here’s a second part of the review as the company sent us additional accessories namely the enclosure kit For SK1 and the AI camera for SK1 which we will report on today. The main structure of the enclosure is made of metal sheets plus a door that opens from the front and a top plate made of tempered glass. The SK1 3D printer enclosure makes the 3D printer more beautiful, protects it from dust, is easy to install, and features a fan and air filter system. It’s also designed to mount the AI Camera for SK1 to help users monitor the SK1 while printing is in progress. TwoTrees Enclosure Case Kit For SK1 The interior of the Twotrees SK1 3D printer enclosure is mostly made of metal and includes a tempered glass door […]
