MP1584 step-down module - 5V output (verified)

Overview

For circuit design, you can refer to this article
: 5V Output Circuit Design - CSDN Blog.
The output voltage is changed by altering the value of resistor R1; the specific formula is mentioned in the article. R1 is not shown in the picture because the wrong resistor was purchased. Soldering a 10k resistor resulted in a stable output of 0.99V, conforming to the formula

. Changing the resistor to 210kΩ resulted in a stable 5V output, which has been verified.

How to remove the serial port feedback information of the development board
How to remove the automatic feedback information of the serial port of the development board s3c2410? For example, connect the development board and the PC, open the serial port software on the PC, an
Finally learned how to solder bga chips
When I soldered before, I just glued a few pins of the chip, and the jtag couldn't connect. Later, I tried a few more times, and the chip blew up almost every time. I was so scared that I didn't dare
STM32 interrupt triggering problem
I used two external interrupts, but one of them was not triggered. Once the program was executed, it entered the interrupt. I don't understand why.Also, sometimes there is a fluctuation on the pin, wh
Problems in developing mapx mobile in evb3.0
After searching online for a few days, I have summarized a few questions. Please give me some advice: 1. Does MapX Mobile support EVB3.0+PPC2002? (According to some people online who have done this, i
【GD32L233C-START Review】+Unboxing【1】
I got the board almost after the holiday, but I kept delaying it, so I'll post an unboxing post now. First, let me introduce this development board. The GD32L233 series MCU has a maximum main frequenc
