Three things to know about LED

In the late 19th century, Thomas Edison invented the first commercially viable light bulb. The bulb works by passing a large amount of current through the filament, which is basically a wire. The filament gets hot, starts to glow, and lights up. This process is very inefficient, less than 5% of the energy goes into […]

Five points for attention in MCU design of low power consumption

The power consumption of MCU should be 176na, but it is 700mA! I can’t bear it. I want to die. Usually, when we use MCU with low power consumption, the actual power consumption often deviates greatly from the theoretical power consumption. For example, in some low to microampere power consumption modes, the low power consumption […]
