First Test of Java on Banana Pi (ARM and RISC-V), Plus a Blinking LED with Pi4J

Thu, 16 Jul 2026 00:00:00 +0000

As part of my 2026 learning goals around Java on RISC-V (see this post about x86 versus ARM versus RISC-V ), I’ve asked various suppliers to send me evaluation boards. I already published these:

Pi4J Joins the Commonhaus Foundation: Securing the Future of Java on Single-Board Computers

Fri, 27 Feb 2026 00:00:00 +0000

Open source software is built on passion, time, and dedication. But passion alone doesn’t guarantee the long-term survival of a project. Maintainers move on, life changes, priorities shift, and sometimes a beloved project simply fades away. Something we want to avoid for the Pi4J project . So I’m very happy that I can share that on February 26, Pi4J got accepted into the Commonhaus Foundation . This is a major step to make sure that this Java library, used by many developers in all kinds of projects, can continue to exist and grow.

I Benchmarked Java on Single-Board Computers: Orange Pi 5 Ultra and Raspberry Pi 5 Lead the Pack

Tue, 24 Feb 2026 00:00:00 +0000

In my “Java on Single Board Computers” series, I already published several posts and videos in which I unpack the board, connect it for the first time, and try to install and run some simple Java code. In this post, I want to share some benchmarks of Java on these boards to get a better idea of the performance we can expect from Java on these platforms.

I Got Java 25 Running on the RISC-V BeagleBoard BeagleV-Fire

After my initial struggles with the BeagleV-Fire in a previous video , I succeeded in getting Java 25 running on RISC-V-powered BeagleV-Fire! Let me walk you through the journey and the steps I took to make it work.

Keeping Single-Board Computers Organized with a 3D Printed Stack

Wed, 14 Jan 2026 00:00:00 +0000

As I shared in previous posts, I want to learn and experiment more with different types of single-board computers in 2026. But I also want to keep them organized and easily accessible. Following the Clean Desk Policy (CDP) in my little home-office also keeps my mind clean :-)

First Test of Java on the Orange Pi (ARM and RISC-V)

Mon, 12 Jan 2026 00:00:00 +0000

As part of my 2026 learning goals around Java on Single Board Computers and RISC-V (see this post about x86 versus ARM versus RISC-V ), I’ve been asking various suppliers to send me evaluation boards. After testing the LattePanda IOTA , I received two boards from OrangePi to evaluate: the OrangePi 5 Ultra (ARM) and the OrangePi RV2 (RISC-V).

Single Board Computers: x86 vs ARM vs RISC-V

Wed, 07 Jan 2026 00:00:00 +0000

Ever since I started my #JavaOnRaspberryPi journey in 2019, which resulted in my book “Getting Started with Java on the Raspberry Pi ”, I’ve been fascinated with these tiny, inexpensive computers. For 2026, I’ve set one of my goals to experiment with Java on various Single-Board Computers (SBC), going beyond my “Raspberry Pi comfort zone.” The market is flooded with SBCs ranging from budget boards (tens of euros) to powerhouses (hundreds of euros). One of the reasons of this price range is the difference between the processors they use. Raspberry Pi uses an ARM processor, but RISC-V is gaining momentum, while Intel maintains its presence. So before I start experimenting, now is the perfect time to compare these three processor families and understand their differences.

First Experiments with Java on the LattePanda IOTA: An Alternative to Raspberry Pi?

Tue, 25 Nov 2025 00:00:00 +0000

After years of experimenting with Raspberry Pi boards, Java, JavaFX, and Pi4J to control electronics, I wanted to explore whether my knowledge and experience could be applied to similar boards from other providers. There are many alternatives available these days, based on ARM, Intel processors, and RISC-V architectures.
