Enable i2c with an sd card reader
- Add files to enable I2C
- In the root of the hassos-boot partition, add a new folder called CONFIG.
- In the CONFIG folder, add another new folder called modules.
- Inside the modules folder add a text file called rpi-i2c.conf with the following content:
Why You Might Need a Raspberry Pi Cluster
“What’s the point of a Raspberry Pi cluster?”
We’ve seen this question being asked so many times, we’ve also seen many vague answers like “because we can”, or “it’s fun”, or “it’s challenging”, or “you get to learn something”, etc.
Here’s the right answer, you build a Raspberry Pi Cluster not just because you can, but because it’s also a low-cost, versatile learning system over all kinds of clustered-computing related technologies.
What is an RPI Cluster
The Official Raspberry Pi Pico Guide
Upon Raspberry Pi‘s release of their first-ever microcontroller board, the foundation also put together a book featuring 139 pages of comprehensive instructions and beginner level tutorials, whether you are a skilled developer, or just playing Pico for the first time, it’s an absolute must-have.
It’s named “Get Started with MicroPython on Raspberry Pi Pico”, you can get it right here.

Rpi Cluster at its final form
Back in 2019, Oracle made a supercomputer with a superb Raspberry Pi 3B+ cluster featuring 1060 boards:
Source: thousand times the fun
Rpi cluster-building has really come a long way, getting multiple Pis together not only means combined performance, it also creates a budget-friendly cluster computing environment, and people love home labs because they get to have full control.
Oftentimes, there may not even be a cluster, you could be buying a 4B just to replace the old Pi 3, or you could merely have multiple Pis doing different works at once: Pi-hole, Kodi, etc. Either way, you get several Pis lying around. And whether you are an owner of a dedicated cluster

Final Upgrade to the Rasberry Pi Rack Mount series
When designing our first Rpi rack mount, all we can think about was compatibility. No matter what Pi models you have, we want to make it possible for you to install all of them with one single bracket. As for the second rack mount, we added additional Micro-to-full-size HDMI adapter boards, so you don’t have to buy extra HDMI cables and jacks.
As for the third one, we’ve decided to make it a Pi 4B exclusive, and this time, we are bringing everything to

The Arduino platform was perhaps the most popular for building a robot
The market has seen a whole bunch of robots based on Arduino, especially Arduino car kits. Over the past few years, UCTRONICS has also released our Arduino smart robot car product line. This leads to the first question we are having here: Why do we use Arduino as the platform for a Robot?
The answer is simple: Arduino is a popular and low-cost platform with excellent code and software support from the open-source community. The Arduino boards, such as the UNO R3, has already been used in a lot of maker projects that could be

Standalone IoT modules
When it comes to development modules for IoT (Internet of Things) applications, there is perhaps nothing more exciting than ESP8266 and its successor ESP32 by Espressif. These cheap yet powerful SoC (system-on-chip) have been used in a lot of IoT systems and also received a great amount of popularity among Electronic Engineers and enthusiasts.
The newer revision - ESP32 - supports both WIFI & Bluetooth wireless connection for a cable-free transmission, which allows itself to be better connected to the Internet for running internet-based and internet-driven services, as well as other embedded and IoT systems that require close and better machine to machine interaction to automate the workflow.
However, the ESP32 SoC is not easily integrated to other circuit boards and devices,

Pi 4b enclosure with air cooling
The market has seen various new accessories for RPi since the release of Pi 4. What’s new on Pi 4, and what are the extra things that we should care about?
The heat issue is a significant one among them. Admittedly, the newest Raspberry Pi is more powerful, but it also generates much more heat, so the Pi 4 temperature control is a bigger issue than ever before. To better cool you Pi 4 down, UCTRONICS recommend you get a Pi 4B enclosure with air cooling.
Fan + heat sinks
What are the current solutions for better cooling? Heatsinks and fans. The heatsinks give your Pi extra areas for the heat dissipation, and the fans bring more air in and out to take away the heat faster once it’s generated. Heatsinks stay on the board easily because they are

What do you need to get started with a Raspberry Pi? Well, you might claim that you’ll only need a power adapter and a micro SD card to unleash the potential of the Pi. However, if you are among the majority of the users who use this as a compact computer, you will always need a screen to monitor what your Pi is doing and interact with it instead of using SSH. So what kind of screens will match the credit-card-size Raspberry Pi? The answer from UCTRONICS is simple: you need a portable screen for a portable computer!

The Raspberry Pi 4 is out for quite a while, and we have got enough time to test our current product’s compatibility with the new Pi, and at the same time build new products around it. As a supplier of all kinds of Raspberry Pi accessories, the PoE support for Raspberry Pi is one of the disciplines which we’ve put a lot of effort into. UCTRONICS PoE splitters and HATs are among the best-selling products from us of all time. Now that we are heading into the Pi 4 era, UCTRONICS will continue to provide Raspberry Pi PoE solutions.
What’s PoE and why PoE support for Raspberry Pi?
PoE is short for Power over Ethernet, which is a solution to deliver both power supply and Ethernet connection with a single Ethernet cable so that
