Professional open-source development platform hardware supplier — Hardkernel has previously released a 64-bit high-performance general development board for global developers, this board, codenamed ODROID-C2, is priced at 40 dollars and is currently being publicly sold on its official homepage.
(ODROID-C2)
ODROID-C2 has a body size of 85 x 56 mm, weighs 40g, and uses the Amlogic 64-bit application processor S905 (4-core ARM Cortex-A53 CPU, 5-core Mali-450@750MHz+ GPU), with a main frequency of up to 2.0GHz,
Time flies, and another year has passed in the blink of an eye. I wonder if everyone still remembers that last year around this time I open-sourced the first matrix WiFi clock. Subsequently, I released a shorter upgraded version as a product in my Taobao store, and many friends purchased it to support me, for which I am very grateful. However, later on, due to a busy work schedule, I had no time to produce it, so I took
This article introduces how to drive an ESP32 OLED display using .Net nanoFramework. We will start from the basics and gradually delve deeper, enabling you to understand and implement the entire process. Whether you are a beginner or an experienced developer, this article will be helpful to you.
The ESP32 development board we are using is the Weixue ESP32-S3-Zero, which is very compact but powerful. This development board uses the ESP32-FH4R2 system-on-chip (SoC), which integrates low-power
The Raspberry Pi 400 is essentially a Raspberry Pi 4 built into a keyboard. This great concept takes me back to my first personal computer. Of course, in the spirit of Raspberry, the complete kit is quite reasonably priced at around $100 (RMB: 660.8). Here are the details provided by Pi Hut:
The Pi 400 packs all the powerful
When you power on your computer and only the fans are running, with no response from the monitor, it certainly indicates a hardware issue. The best approach is to use a process of elimination to identify the problem. Here’s how:
1. Press the Caps Lock key on the keyboard. If the light turns on, it indicates a fault with the graphics card, monitor, or other hardware.
2. If the keyboard

Many large companies choose to keep their hardware closed-source, creating technological barriers and patent copyrights that hinder the development of small-scale innovators. Open source hardware allows entrepreneurs to more easily turn their ideas into reality.

Arduino Uno is very common in the Maker community. Arduino comes in many different sizes and features, but here we choose Arduino Uno as a representative.
In this article, we will learn how to use Arduino to drive the Nokia 5110 display. Previously, I learned how to drive the Nokia 5110 display with Raspberry Pi to show system information.
