The PA or PB pins of the same group of STM32F030 IO ports are set to output a unified high level. Why is the voltage of some IO ports only around 0.9V, while some can reach 3.3V, and using an external...
ad9 In the same project, I copy a schematic file 1 to generate another schematic file 2, but every time I synchronize it to the PCB, the components in the copied schematic 2 have to be deleted and the...
For a resistor, 103KΩ is often used to express the resistance value. Some electronic circuit books say that 103K=10 x 10 3 Ω , that is, 10 4 Ω. Some books say that it is 1.0 x 10 3 Ω, that is, 10 3 Ω....
