PCB Network News Sharing an interesting piece of information: using wire to create a “circuit board”. I hope it inspires colleagues in the industry. What is Freeduino? It is an Arduino UNO board without any circuit board. It interconnects components using a technique called freeform, utilizing wires or copper instead of a circuit board. It … Read more
If you don’t want to miss my updates, remember to check the public account in the upper right corner and set it as a star, drop a star for me. Many MCU manufacturers can complete PWM control through internal registers, such as Arduino, STM32, etc. This integration greatly simplifies the development process, allowing you to … Read more
Do you want to play with circuits but don’t know how to design a PCB? You can! Before PCBs existed, components were connected directly (as imagined by Teacher Su). In fact, even when we have PCB design issues that require rework, we often use various jumper wires to make our circuits work. So, even if … Read more
