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 […]

A closer look at Raspberry Pi RP2350’s HSTX high-speed serial transmit interface

The Raspberry Pi RP2350 microcontroller adds an HSTX (High-Speed Serial Transmit) interface adding the PIOs (Programmable IOs) introduced on the Raspberry Pi RP2040 three years ago. The RP2350 MCU now has three PIOs and one HSTX interface going over 8x GPIOs. So let’s try to better understand what HSTX is exactly, what it is used for, and how it differs from PIOs. We’ll also check out some programming examples in C and MicroPython. The high-speed serial transmit (HSTX) interface is detailed in the RP2350 datasheet starting on page 1118 where it reads “The high-speed serial transmit (HSTX) interface streams data from the system clock domain to up to 8 GPIOs at a rate independent of the system clock”. Reading further, we also learn that it runs at 150 MHz enabling up to 300 Mbps per pin with DDR output operation, or a combined 2,400 Mbps over 8 pins if I […]

Building a workstation with Radxa ROCK 5 ITX (Arm) or Milk-V Jupiter (RISC-V) mini-ITX motherboard – Part 1: The hardware

Milk-V Jupiter ROCK 5 ITX mini ITX NAS enclosure

Radxa ROCK 5 ITX is a mini-ITX motherboard powered by a Rockchip RK3588 octa-core Cortex-A76/A55 processor, and the Shenzhen Milk-V Jupiter is another mini-ITX motherboard, but based on SpacemIT K1 octa-core 64-bit RISC-V processor instead. When Radxa contacted me about reviewing those, I thought it would be interesting to review a complete kit with a mini-ITX case since I had never built this type of system myself. Yesterday, I was surprised to receive two large packages and thought maybe a company sent me a 3D printer or laser engraver kit, but instead, I got one package with the two Arm and RISC-V mini-ITX motherboards and another with a mini-ITX NAS enclosure with 6x SATA bays. Radxa ROCK 5 ITX unboxing Let’s look at the ROCK 5 ITX motherboard and accessories first. The motherboard ships with a rear panel and two screws for the M.2 module. The motherboard features the Rorkchip […]

Review of AgroSense LoRaWAN Smart Agriculture sensors with the SenseCAP M2 LoRaWAN gateway

Today, I will be reviewing the AgroSense LoRaWAN sensors from Makerfabs designed for high-precision agriculture. This time, I received four sets of sensors designed for measuring environmental data and a Seeed Studio SenseCAP M2 LoRaWAN gateway. Below is the list of items I received. AgroSense LoRaWAN Barometric Pressure Sensor – Measures the barometric pressure in a 300 to 1100 hPa range with ±0.12 hPa accuracy and 0.01 hPa resolution. AgroSense LoRaWAN Light Intensity Sensor – Measures the light intensity in a 1 to 65535 lx range with ±1 lx accuracy and ±20% resolution. AgroSense LoRaWAN Temperature & Humidity Sensor – Measures temperature and humidity in the atmosphere in the ranges of -40°C to 85°C and 0 to 100 %RH with accuracy of ±0.2°C and ±0.2% RH respectively. AgroSense LoRaWAN Industrial Temperature Sensor – Measures temperature in the industrial high-temperature environments in the -60°C to 200°C range with ±0.1°C accuracy and […]

How to easily enable MediaTek MT7922 Bluetooth on Ubuntu 24.04

MediaTek MT7922 WiFi 6 and Bluetooth 5.3 modules have recently been found in several mini PCs, but Bluetooth would not work in Linux due to a lack of drivers. In this post, we’ll show how to easily enable Bluetooth in MediaTek MT7922 modules when running Ubuntu 24.04. We previously noted that Ian Morrisson submitted a patch adding the IDs for the MT7922 module (Azurewave AW-XB591NF) used in recent GEEKOM mini PCs last March. In theory, you could have rebuilt the Linux kernel, but now that Linux 6.10 has been released, it’s much easier since Canonical has made the Linux 6.10 kernel available for Ubuntu, so we only need to install it and problem solved! Ubuntu 24.04 ships with Linux 6.8, we can see a Bluetooth opcode error in the kernel log.

RT-Thread Vision board review – Part 1: OpenMV on Renesas RA8D1 Cortex-M85 microcontroller

RT-Thread VIsion board vs WeAct STM32H743

I am always interested in real-time operating systems (RTOS) for microcontrollers (MCUs) with my past backgrounds in µC/OS-II, mbed, and FreeRTOS. When the opportunity arose to get my hands on the RT-Thread Vision Board, thanks to the RT-Thread team and CNX Software, I was excited to check it out. This board, a collaboration between RT-Thread and Renesas, packs a powerful Renesas RA8D1 Cortex-M85 MCU and comes pre-loaded with OpenMV firmware. OpenMV’s MicroPython engine lets you jump right into embedded vision development, perfect for experimenting with computer vision tasks. But the real power lies in RT-Thread’s ability to handle tasks very quickly, which we’ll explore with C/C++ development in part two. This first part will focus on getting you familiar with the hardware using the OpenMV firmware, making it a smooth entry point for beginners. Plus, I have a collection of other Renesas evaluation boards, so you can bet I’ll be […]

How to repair/replace a WiFi antenna in a mini PC

In this short tutorial, we’ll show how to repair/replace a WiFi antenna in a mini PC. We’ll use GEEKOM A8 Mini PC as a test device because one of its WiFi antennas is attached to the top plastic cover, and it may potentially get damaged when the user opens the case to change or upgrade the SSD or memory sticks. This happened to us during the teardown of the GEEKOM A8 mini PC as shown in the image below. While WiFi still works with one antenna, the performance is quite better when two antennas are connected so we decided to repair the mini PC. We asked a few local shops, but they would only sell WiFi modules with antennas and none would just sell the antennas themselves. But luckily, such WiFi antennas can easily be purchased online in pairs. The first time, we purchased a WiFi antenna pair from Shopee […]
