Why Do Microcontrollers Have Multiple VDD Pins?

2026-01-09 by boardor

We know that typical IC components usually have only two power pins, one is Vcc or Vdd, and the other is Gnd or Vss. However, modern MCUs often have multiple power pins; what is the reason for this? Taking a 100-pin MCU as an example, we can see that it has 5 sets of VDD/VSS, … Read more

Stop Focusing on Chips When Buying DACs: Become an Expert in DAC Selection!

2026-01-07 by boardor

After attending many audio exhibitions, I found that the most common marketing tactic at some domestic DAC booths is to showcase the chip. Many audiophiles evaluate a DAC solely based on the statement: “This DAC uses the xx chip, and that chip sounds bad.” But have you ever thought, if the chip determines success or … Read more
