Regarding the relationship between capacitance and frequency, coupling capacitors, filter capacitors, bypass capacitors, etc. are often used in amplifier circuits. I want to know the relationship betw
1. Introduction
The Bluetooth connection has been introduced before, so we need to do something interesting. The board does not have its own audio interface, but it has Bluetooth, so I thought of usin
I recently made a switch with RS485 interface, using TI's SN75LBC184 chip. The schematic diagram is as followsMCU uses serial port to transfer to 485 through hardware circuit. The 485 circuit on the u
introductionAt present, the research on smart home mainly takes hardware devices equipped with STM32 chips[1] as the central controller. At the same time, most smart home cloud platforms are built on
SummaryNoisecan sometimes have unpredictable effects on the DUT. Therefore, if the DUT is sensitive to noise in the DC power supply input, it is necessary to reduce the input noise as much as possible
