ST-LINKV2 minimalist version

Overview

The two STLINKs I bought before were all burned. The output IO ports were all broken.

I was heartbroken, so I drew this ST-LINKV2 with ESD protection.

Features:

A 100uf capacitor is added to the input to make the power supply more stable.

Simplified some unnecessary components and removed the 5V output (to avoid connecting the wrong voltage)

Current limiting resistor and ESD protection added to output

All original parts are concentrated on the front, making it convenient for teppanyaki

Proofing and verification passed

Note: The LDO pin is a bit special and different from the usual ones.

Summary of Common Protection Circuits for Power Supply Circuits
In view of the fact that there are some unstable factors in the power circuit, the circuit designed to prevent such unstable factors from affecting the circuit effect is called a protection circuit .

NIOSII system clock experiment 2
I want to try to enable three system clock services in NIOSII so that the three LEDs flash at 2Hz, 1Hz, and 0.5Hz respectively, but I have no idea. Which part should be modified for the program that u
I want to buy an oscilloscope. Can you help me choose one?
Dear friends, our company needs an oscilloscope that can measure microampere current and the corresponding probe. I would like to ask if you have a brand and model with a higher cost performance.
Dual-gate field effect transistor - the most economical choice for controllable gain amplifier
The dual-gate field effect transistor has a source, a drain and two gates. There is a silicon dioxide insulating layer between the metal gate and the channel, so it has a very high input resistance. T
