1. Hardware Preparation You’ll need an Arduino development board (such as Arduino Uno) and several LED lights. Connect the anode (long leg) of the LED lights through a current-limiting resistor (usually a few hundred ohms, such as 220Ω, to prevent excessive current from damaging the LEDs) to the digital pins of the Arduino board (for … Read more
The prices of automotive electronic products are generally quite high, one of the main reasons being the use of automotive-grade electronic components. But what kind of electronic components qualify as automotive-grade? Let’s first look at the application of electronic components in cars and how it differs from general consumer electronics. Environmental Requirements Temperature: Automotive electronics … Read more

1. STM32 and Selection 1.1 STM32 vs 51 Microcontroller Both STM32 and 51 are types of small computer chips that allow us to write code and store it within. For example, we can control a pin to switch between 5V and 0V, connecting an LED to this pin to achieve a blinking effect. This operation … Read more
Flying probe testing is currently the best solution for some major issues in electrical testing. It uses probes to replace the test bed, employing multiple motor-driven electrical probes that can move quickly to contact the pins of the device for electrical measurements. During the production process of PCB boards, it is inevitable that external factors … Read more
In the second half of 2020, the global chip shortage was caused by a supply-demand imbalance due to the outbreak of the pandemic and the rise of new energy. The most typical example is the automotive MCU. The outbreak of the global pandemic led to a reduction in the capacity of wafer fabs, with companies … Read more
